Wherein, rim(ming) light be comparable in face of video camera direction carry out light irradiation so that game object The position at its edge shows backlight effect in the state of video camera, so that the profile to the game object being taken carries out It delineates, so that game object is mutually separated with game background, keeps picture level abundant, increase visual format aesthetic feeling.

Currently, in the prior art, what the direction of video camera and the direction of light source were always bound, i.e., it is deposited between both direction In fixed angular relationship, no matter camera rotation to where, light source always comes from the same side so that game object Show rim(ming) light.

However in full view game, since it is desired that the function from each view game state is provided a user, because Light source (as sunlight is exactly fixed) that this light source is usually a fixed position, not bound with video camera, below with reference to Fig. 2 is illustrated the performance of rim(ming) light, and Fig. 2 is the interface schematic diagram of the method for profile photocontrol provided in an embodiment of the present invention One.

As shown in Fig. 2, being illustrated in Fig. 2 under 4 different angles of camera direction and light source direction, the same trip The corresponding different 4 kind state showed of play object, in the figure 2 example, wherein the direction of light source does not change, in Fig. 2 4 kinds of states be angle between light source direction and camera direction (not consecutive variations are intended merely to show being changed Different states), alternatively, for the ease of being understood referring to fig. 2, opposite it can be construed to, when game object is from the right side of light source When side gradually goes to left side (angle of video camera remains at the front of game object), it is equivalent to, the direction of light source is opposite Right side is gradually gone to from left side in game object.

However, the light-receiving surface of game object can be made to show greatly when camera rotation is extremely consistent with the direction of light source The exposure of range, such as the state that game object 201 (in Fig. 2 from left to right count third images) is showed, so as to cause trip Object play in the unreasonable of present condition, based on the above issues, the present invention provides a kind of method of profile photocontrol, so that from light The angle in source is not in large-scale exposure when observing game object, to increase the reasonability of game object.

It is illustrated below with reference to specific embodiment, is introduced first in conjunction with Fig. 3, Fig. 3 mentions for the embodiment of the present invention The flow chart one of the method for the profile photocontrol of confession.

As shown in figure 3, this method comprises:

S301, according to the first angle between light source direction and the normal direction on each vertex of game object, obtain light source Distributed intelligence.

In the present embodiment, light source is corresponding with light source direction, which angle is light source direction be used to indicate light source to game Object is irradiated, such as may refer to direction indicated by the dotted arrow of light source 103 in Fig. 1.

Wherein, game object include multiple vertex, the respective normal direction of each vertex correspondence, wherein normal direction be Refer to the direction perpendicular to the plane where the vertex, such as may refer to Fig. 1, game object 101 includes six planes, Mei Geping Bread contains multiple vertex, and wherein the normal direction on multiple vertex is direction indicated by arrow 104 in plane 1, more in plane 2 The normal direction on a vertex is direction indicated by arrow 105, and the normal direction on multiple vertex is arrow 106 in plane 3 Indicated direction.

It will be understood by those skilled in the art that Fig. 1 is only the schematical introduction carried out with a cube, in reality In scene of game, specific game object can correspond to many planes, therefore each vertex corresponds to respective normal direction.

Secondly, normal direction can reflect the direction on each vertex of game object, wherein light source direction and each vertex There are the first angles between normal direction can obtain according to the first angle between light source direction and the normal direction on each vertex To for reflecting the distribution of light sources information of the distribution of the Lighting information of light source on the surface of game object.

Such as the normal direction on light source direction and certain vertex shows that the vertex is faced directly on the contrary, then the first angle is 180 ° Light source (as light-receiving surface), alternatively, such as light source direction is identical as the normal direction on certain vertex, then the first angle is 0 °, table The bright vertex is back to light source (as shady face), alternatively, such as light source direction is vertical with the normal direction on certain vertex, then first presss from both sides Angle is 90 °, shows that the vertex is located exactly at the intersection of shady face and light-receiving surface, wherein it is understood that working as light source side To when being greater than 90 ° with the normal direction angle on vertex, then the position where the vertex is to be in backlight (light source irradiation less than) State.

Being above take the first angle as 180 ° (direction is consistent), the first angle is 0 ° (contrary) and the first angle is It is illustrated for 90 ° (direction is vertical), it will be understood by those skilled in the art that each except above-mentioned three kinds of first angles A angle corresponds to respective distribution of light sources information, for indicating distribution of the illumination on each vertex of game object, In optional embodiment, distribution of light sources information can be for example indicated with angle, or can also be indicated with numerical value, this Embodiment is not particularly limited this.

In an alternate embodiment of the invention, may exist multiple light sources in scene of game, it can be simultaneously in a such as scene of game There are sunlights and light, and in the present embodiment, light source can be understood as individual main light source, i.e., are showed to game object Effect of shadow influence maximum light source, alternatively, light source is also understood that the synthesis light source obtained for multiple light sources collective effect, The present embodiment does not limit this.

S302, according to the second angle between the normal direction on each vertex of direction of visual lines and game object, obtain profile Light distribution information.

It is appreciated that the direction that video camera is placed is that preset user checks direction, root during making game According to the difference for the position that video camera is placed, game object can be shot from different directions.It should be noted that the present invention is implemented The direction of camera is carried out reversely, as direction of visual lines in example.In the present embodiment, profile light distribution information is used to indicate wheel Wide light the surface of game object distribution, for example, see Fig. 1, video camera from the angle shot game object of plane 6, therefore When showing scene of game, it should show rim(ming) light in the surrounding of plane 6.

It will be understood by those skilled in the art that the game object that user observes in graphical user interfaces is actually two Dimension, there is always marginal positions for a two-dimensional object, and wherein the distributing position of rim(ming) light is actually to shoot from video camera The marginal position for the game object that angle looks over.

In the present embodiment, there are the second angles between direction of visual lines and the normal direction on each vertex, according to the second angle It is available for the profile light distribution information of the marginal position of instruction game object.

Such as direction of visual lines is consistent with the normal direction on certain vertex, then the second angle is 0 °, shows that the vertex is faced directly and takes the photograph Camera (position that the direction of observation of as user is faced directly), alternatively, such as direction of visual lines is vertical with the normal direction on certain vertex, Then the second angle is 90 °, show the vertex perpendicular to video camera (as most marginal position), wherein it is understood that When direction of visual lines and the normal direction angle on vertex are less than 90 °, then the position where the vertex is the position that user does not observe It sets, it, can only be to game object of second angle between 90 ° to 180 ° because screen is shown with two-dimensional state Part is shown.

S303, according to rim(ming) light thickness coefficient adjustment profile light distribution information, to control the rim(ming) light of game object, In, rim(ming) light thickness coefficient is according to distribution of light sources information acquisition, and rim(ming) light thickness coefficient is used to indicate the thickness of rim(ming) light.

Specifically, profile light distribution information indicates the marginal position of the game object from the angle of video camera, it is false If light source is located at the left side of video camera, that is, show that light source irradiates game object from left side, then the marginal portion on the left of game object For light-receiving surface, the marginal position that should be showed on the right side of large range of rim(ming) light and game object is shady face, should not be in Existing rim(ming) light (performance black), and from the left side of game object to right side (light-receiving surface to shady face), the profile of game object Light should show the smaller and smaller state of range, so that the presentation of rim(ming) light can accurately reflect the direction of main light source.

In the present embodiment, the rim(ming) light thickness system for the thickness for being used to indicate rim(ming) light is obtained according to distribution of light sources information Secondly number is adjusted profile light distribution information according to rim(ming) light thickness coefficient, because rim(ming) light thickness coefficient is according to light Source distribution information obtains, therefore when according to rim(ming) light thickness coefficient adjustment profile light distribution information, corresponding game object is in The rim(ming) light revealed also shows corresponding distribution of light sources information, the i.e. direction of main light source.

In an optional implementation manner, for example, can be set rim(ming) light thickness coefficient and distribution of light sources information present it is negative Correlativity, this, which sentences distribution of light sources information and is expressed as example with numerical value, is illustrated, when distribution of light sources information uses other forms When (such as the first angle) indicates, implementation is similar, specifically, the numerical value of distribution of light sources information is bigger, (vertex is located Light-receiving surface), corresponding rim(ming) light thickness coefficient is smaller (rim(ming) light showed is thicker), so that game object showed Rim(ming) light range in light-receiving surface is larger, corresponding, is more proximate to the part of shady face, and the range of rim(ming) light is smaller.

Alternatively, positive correlation can also be presented with distribution of light sources information in rim(ming) light thickness coefficient, then it at this time for example can be with Setting rim(ming) light thickness coefficient is smaller, and the rim(ming) light showed is thinner, it will be understood by those skilled in the art that according to distribution of light sources The specific implementation that information obtains rim(ming) light thickness coefficient can be set according to actual needs, as long as guaranteeing according to profile After light thickness coefficient adjustment profile light distribution information, the profile optical range of the light-receiving surface of game object is larger, light-receiving surface extremely Shady face profile optical range is gradually reduced, so as to reflect the direction of main light source.

The method of profile photocontrol provided in an embodiment of the present invention, comprising: according to each top of light source direction and game object The first angle between the normal direction of point, obtains distribution of light sources information.According to each vertex of direction of visual lines and game object The second angle between normal direction, obtains profile light distribution information.Believed according to rim(ming) light thickness coefficient adjustment profile light distribution Breath, to control the rim(ming) light of game object, wherein rim(ming) light thickness coefficient is according to distribution of light sources information acquisition, rim(ming) light Thickness coefficient is used to indicate the thickness of rim(ming) light.By determining rim(ming) light thickness coefficient according to distribution of light sources information, and according to Rim(ming) light thickness coefficient adjustment profile light distribution information, so that light source can be accurately reflected by controlling when rim(ming) light is presented in game object Direction, to increase the reasonability of the rim(ming) light of game object.

The difference is that indicating that the plane where the vertex when the angle of direction of visual lines and normal direction is 90 ° It is parallel with direction of visual lines, thus angle be 90 ° vertex i.e. sight it is observed that game object marginal portion, i.e., The vertex at edge is illustrated in Fig. 6.

Alternatively, also indicating that the plane and sight where the vertex when the angle of direction of visual lines and normal direction is 0 ° Direction is vertical, therefore the part that the second angle is faced directly by 0 ° of corresponding vertex i.e. sight, is not also just marginal position, It can be found in the part of White vertex in Fig. 6.

In an alternate embodiment of the invention, the range of the second angle is 0 ° to 180 °, wherein although the range of the second angle is 0 ° To 180 °, but we are when determining profile light distribution information according to the second angle, it is only necessary to portion of the range between 0 ° to 90 ° Point, wherein 90 ° to 180 ° of part be observed by sight less than part, therefore do not need to handle this part (available but It is not necessary to processing), can by determining profile light distribution information according only to the part between 0 ° to 90 ° Effectively reduce calculation amount.

S405, according to the corresponding relationship between preset angle and Distribution Value, obtain the second angle pair of each vertex correspondence The Distribution Value answered, wherein Distribution Value is used to indicate whether vertex is located at outline position.

In the present embodiment, the second angle is corresponding with Distribution Value, and wherein Distribution Value is used to indicate whether vertex is located at profile Position, Distribution Value is similar with the brightness value of above-mentioned introduction, and only indicated content is different, specifically, angle and Distribution Value it Between there are preset corresponding relationship, the corresponding relationship of angle and Distribution Value is referred to the corresponding relationship of angle and brightness value, this Place repeats no more.

In an optional implementation manner, such as Distribution Value can be obtained using formula four:

NoV=saturate (dot (N, V)) formula four

Wherein, N indicates that normal line vector, V indicate sight line vector, and dot is dot product function, and for obtaining the second angle, NoVNoV is Distribution Value, wherein the effect of function saturate (x) is the return value 0 if x value is less than 0.If x value is greater than 1, Then return value is 1, if x between 0 to 1, directly returns to the value of x, to determining Distribution Value between 0 to 1.

It will be understood by those skilled in the art that the black and white in Fig. 6 is not lighting effect, it is intended merely to show model surface The positional relationship on each vertex and direction of visual lines, to indicate whether vertex is located at outline position.

S406, the corresponding Distribution Value of the second angle according to each vertex correspondence, obtain profile light distribution information.

Specifically, Distribution Value can be used to indicate that profile light distribution information, wherein Distribution Value is corresponding with the second angle 0 Numerical value between to 1, when the second angle is 0 °, corresponding Distribution Value is 1, shows that the vertex is the part for facing video camera directly (not in outline position)；When the second angle is 90 °, corresponding Distribution Value is 0, shows that the normal direction on the vertex is vertical In the direction (being located at outline position) of video camera, when the second angle is 180 °, corresponding Distribution Value is -1, shows that the vertex is Back to the part of video camera, wherein the second angle and Distribution Value are in inversely prroportional relationship.

In an optional implementation manner, in the corresponding relationship between preset angle and Distribution Value, angle and distribution It is worth negative correlation, i.e. the second angle is bigger, and corresponding Distribution Value is smaller, is not located at the position of profile, this field skill Art personnel are appreciated that the range that the outline position in the present embodiment can be not absolute, can be the range of referring to property.

In an alternate embodiment of the invention, for the ease of handling rim(ming) light, reverse phase processing is carried out according to Distribution Value, thus Profile light distribution information is obtained, wherein reverse phase processing can be understood as black and white reverse phase, i.e. script Distribution Value is 1 (facing video camera directly) Vertex after reverse phase is handled, obtain reverse phase Distribution Value be 0, script Distribution Value be 0 (marginal position) vertex pass through reverse phase After processing, obtaining reverse phase Distribution Value is 1, to obtain rim(ming) light breadth coefficient, the position that wherein rim(ming) light breadth coefficient is 1 is For the marginal position of game object, that is, the position of rim(ming) light should be shown.

In an optional implementation manner, such as reverse phase processing can be carried out according to formula five:

RimFactor=1.0-Nov formula five

Wherein, Nov is Distribution Value, and RimFactor is profile light distribution information because in the present embodiment NoV be 0 to 1 it Between numerical value, therefore using formula five may be implemented reverse phase processing, to determine profile light distribution information.

Illustratively, treated that profile light distribution information can be as shown in fig. 7, its marginal position be schematically in for reverse phase Reveal white, its corresponding profile light distribution information is 1.

S407, according to distribution of light sources information and default negative correlation model, obtain rim(ming) light thickness coefficient, wherein preset negative Correlation model is used to indicate the negative correlativing relation between distribution of light sources information and profile thickness coefficient.

In the present embodiment, it can control the rim(ming) light of game object, by adjusting profile light distribution information to guarantee When light source direction is identical with direction of visual lines, the light-receiving surface of game object is not in large-scale exposure, therefore also needs basis Distribution of light sources information is adjusted profile light distribution information, shows reasonability to promote the rim(ming) light of game object.

Specifically, rim(ming) light thickness coefficient is the coefficient for being used to indicate the thickness of rim(ming) light, wherein rim(ming) light thickness coefficient Specific effect can be found in Fig. 8, the corresponding rim(ming) light (wheel shown of thickness coefficient of 6 different rim(ming) lights is given in Fig. 8 The soft degree of wide light is fixed), wherein being from left to right respectively obtained when rim(ming) light thickness coefficient is arranged from 0 to 1 The expression effect of rim(ming) light.

As can be seen from Figure 8, rim(ming) light thickness coefficient is smaller, and the profile optical range showed is bigger, therefore in fig. 8 With the increase of from left to right rim(ming) light thickness coefficient, gradually thinning state is presented in the rim(ming) light of game object, and finally disappears It loses on the surface of game object.

It is understood that when user observes game object, it is assumed that light source direction is in the left side of game object, in order to protect The reasonability that shows of card rim(ming) light, it is therefore desirable to the profile optical range that light-receiving surface (left side of game object) is arranged is larger, from by The profile optical range of smooth surface to penumbra is gradually reduced, and rim(ming) light is not presented in shady face, corresponding, needs that game pair is arranged When as light-receiving surface (the corresponding brightness value of the first angle is bigger), rim(ming) light thickness coefficient is a lesser value (profile optical range Greatly), when game object is not light-receiving surface (the corresponding brightness value of the first angle is smaller), rim(ming) light thickness coefficient is one biggish Value (profile optical range reduces until rim(ming) light is not presented), i.e., should be corresponding between distribution of light sources information and rim(ming) light thickness coefficient Negative correlativing relation is presented.

Therefore, the preset negative relevant mode being provided in the present embodiment between distribution of light sources information and rim(ming) light thickness coefficient Type, wherein default negative correlation model is used to indicate the negative correlativing relation between distribution of light sources information and profile thickness coefficient, below A kind of possible implementation of default negative correlation model is introduced by taking formula six as an example:

RimWide=1.2-NoL_org × 0.5 × cRimWide formula six

Wherein, RimWide is rim(ming) light thickness coefficient, and NoL_org indicates the corresponding brightness value of the first angle, cRimWide It is the rim(ming) light thickness factor, is used for adjustment profile light thickness coefficients R imWide, wherein with the increase of cRimWide, RimWide can accordingly reduce, and can voluntarily be configured according to actual needs, referring to formula six, distribution of light sources information i.e. and Rim(ming) light thickness coefficient is inversely prroportional relationship.

Specifically, the range of NoL_org is -1 to 1 in the present embodiment, the default negative correlation introduced referring to above-mentioned formula six Model, it is assumed that cRimWide 1, when vertex is located at light-receiving surface, NoL_org 1, corresponding RimWide are 0.7；Work as vertex When positioned at penumbra, NoL_org 0, corresponding RimWide are 1.2；When vertex is located at shady face, NoL_org be- 1, corresponding RimWide are 1.7, therefore the reduction with brightness value NoL_org from 1 to -1, corresponding rim(ming) light thickness coefficient RimWide is increased with it, and the profile optical range shown is also smaller and smaller, so that the profile luminous energy that game object shows The direction of enough accurately reflection main light sources.

And in conjunction with Fig. 8 it is clear that, when RimWide is 1, the rim(ming) light on game object surface is just substantially It disappears, referring to above-mentioned introduction, before NoL_org is decreased to 0, corresponding RimWide has just had exceeded 1 range, right The effect that should be presented be game object each vertex since light-receiving surface to the place for having not arrived shadow line, game object The rim(ming) light that shows of edge just faded away, to ensure that the shady face of game object is not in profile Light, i.e. rim(ming) light only appear in the light-receiving surface side of game object, to increase the reasonability that game object shows rim(ming) light.

In an alternate embodiment of the invention, referring to Fig. 8 A, when rim(ming) light thickness coefficient is 0, the profile optical range showed is most Greatly, be similar to the state that rim(ming) light is presented in all vertex, the present invention when camera direction is consistent with main light source direction, Need to guarantee that game object will not show the exposure of large area, it is therefore desirable to which rim(ming) light thickness coefficient is set so that game Object will not show the state of the leftmost side Fig. 8 game object.

(i.e. the first angle corresponding brightness value) is closed in inverse proportion specifically, rim(ming) light thickness coefficient and distribution of light sources information System, therefore in rim(ming) light thickness coefficient minimum, there should be the corresponding brightness value of the first angle maximum (for 1), accordingly to keep away Exempt from the state for leftmost side game object in Fig. 8 occur, it is therefore desirable to which setting is maximum (for 1) in the corresponding brightness value of the first angle When, corresponding rim(ming) light thickness coefficient is minimum but is not 0, and referring to formula six, when vertex is located at light-receiving surface, NoL_org is 1, corresponding RimWide are 0.7, although so that the state comparison for the rim(ming) light that the light-receiving surface of game object shows is thick, But also it is unlikely to the state for large area exposure occur.

Above-mentioned formula six is a kind of schematical introduction, it will be understood by those skilled in the art that numerical value therein, ginseng Number can also be replaced, as long as default negative correlation model can indicate the negative between the second angle and rim(ming) light thickness coefficient Pass relationship, and guarantee that corresponding rim(ming) light thickness coefficient is not 0 in the corresponding brightness value maximum of the second angle, this Embodiment to this with no restriction.

S408, according to rim(ming) light thickness coefficient adjustment profile light distribution information, to control the rim(ming) light of game object, In, rim(ming) light thickness coefficient is according to distribution of light sources information acquisition, and rim(ming) light thickness coefficient is used to indicate the thickness of rim(ming) light.

Specifically, the implementation of S408 is similar with S303.

It is worth noting that on the vertex of marginal position, rim(ming) light, therefore the present embodiment should not do not showed In be only " profile light distribution information " is adjusted according to rim(ming) light thickness coefficient, and wherein profile light distribution information indicate Be rim(ming) light position, that is to say, that the present embodiment is only adjusted the rim(ming) light of the marginal position of game object, with The reasonability that rim(ming) light is presented in enhancing game object will not show rim(ming) light, simultaneously for not being the vertex of marginal position The lighting effect that the present embodiment shows it not will do it processing.

When light source direction is consistent with the direction of video camera, the position of rim(ming) light indicated by profile light distribution information is The position of the two sides of game object, therefore the center (non-edge position) of game object will not show rim(ming) light.

Meanwhile the corresponding brightness value of the first angle (NoL_org) and the corresponding Distribution Value of the second angle (NoV) are one at this time Sample, when Distribution Value is 0, indicate that the vertex is located at the marginal position of game object, and when brightness value is 0, indicate the vertex Positioned at the intersection of light-receiving surface and shady face, therefore marginal position will not show rim(ming) light, so as to avoid the prior art In when light source direction is consistent with the direction of video camera caused game object a wide range of exposure, enhance game object presentation The reasonability of state.

In one possible implementation, the present embodiment can also be according to the soft coefficient in rim(ming) light edge or/and default Interpolation model is adjusted profile light distribution information, wherein default interpolation model is for the distribution to profile light distribution information Range is adjusted, and the soft coefficient in rim(ming) light edge is used to indicate the soft degree of rim(ming) light.

Soft degree indicated by the soft coefficient of rim(ming) light is illustrated below with reference to Fig. 8 B, gives difference in Fig. 8 B The corresponding rim(ming) light shown of the soft coefficient of 6 rim(ming) lights effect (wherein rim(ming) light thickness is fixed), wherein from a left side The expression effect of obtained rim(ming) light when to right respectively setting rim(ming) light thickness coefficient from 0 to 1.

It can be seen from fig. 8b that the soft coefficient of rim(ming) light is bigger, the rim(ming) light showed is softer, therefore in the fig. 8b With the increase of from left to right rim(ming) light thickness coefficient, gradually soft state is presented in the rim(ming) light of game object, can be observed The state of the rim(ming) light showed to game object is more lively.

In one possible implementation, presetting interpolation model is smooth interpolation model, wherein the smooth interpolation mould Type is used to generating the profile light distribution information of script into the smooth excessiveness between the range after interpolation, to realize to rim(ming) light point The smooth increase or reduction of the range of cloth coefficient, so that the rim(ming) light that game object shows is more lively.

A kind of possible implementation is introduced by taking formula seven as an example below:

Rim=smoothstep (RimWide-RimSoftness, RimWide+RimSoftness, RimFactor) formula seven

Wherein, RimWide is rim(ming) light thickness coefficient, and RimSoftness is the soft coefficient in rim(ming) light edge, RimFactor is profile light distribution information, and rim is the range of rim(ming) light, is used to indicate the state that final rim(ming) light shows, Smoothstep function therein is smooth interpolation function, and the function is introduced first below.

Smooth interpolation function is introduced first, such as has smoothstep (a, b, x), wherein a, b are interpolation parameter, X is interpolation variable, then the effect of smooth interpolation function is the smooth transition generated between 0 to the 1 of interpolation variable x, specifically , it can refer to the following table 1:

Table 1

Below with reference to formula seven citing be illustrated, it is assumed that RimWide 0.5, RimSoftness 0.3, then correspond to a, B is respectively 0.3 and 0.8, and RimFactor (profile light distribution information) range of script is 0 to 1 in embodiment, by smooth Interpolation, can be right by the Ratage Coutpressioit of profile light distribution information in 0.3-0.8, so that the comparison of rim(ming) light is stronger The rim(ming) light answered is also just sharper keen.

Referring to Fig. 7 and Fig. 9, state in Fig. 9 is the rim(ming) light when RimWide be 0.5, RimSoftness is 0.3 The state shown, it can be seen that rim(ming) light presents sharper keen state.

Or, it is assumed that interpolation parameter a, b is respectively -0.3 and 1.7, then the range of corresponding profile light distribution information will It is extended between -0.3 to 1.7, thus the comparison of weakened outline light, so that rim(ming) light shows softer state.

The above is only combine smoothstep function carry out illustrative introduction, not unique implementation, wherein Default interpolation model can be set according to actual needs, the present embodiment to default interpolation model with no restriction, if its It can be realized the change of the range to profile light distribution information.

It will be understood by those skilled in the art that combined according to the soft coefficient in rim(ming) light edge, default interpolation model above And rim(ming) light thickness coefficient is adjusted the introduction of progress to profile light distribution information, however the soft coefficient of above-mentioned rim(ming) light It is for default interpolation model so that the effect of rim(ming) light performance is more lively and setting, therefore the present embodiment can root Profile light distribution information is adjusted according to the soft coefficient of rim(ming) light thickness coefficient and rim(ming) light edge or/and default interpolation model It is whole, profile light distribution information can also be adjusted according only to rim(ming) light thickness coefficient, can be corresponded to so that game pair As the rim(ming) light showed accurately reflects light source direction, implementation is similar with above-mentioned introduction, and details are not described herein again.

Wherein, profile light distribution information refers specifically to the specific range of the display position for having shown rim(ming) light and display, thus According to profile light distribution information adjusted, controls game object and show corresponding rim(ming) light, in conjunction with Fig. 9 B to game object The rim(ming) light showed is illustrated, and has been put on display in Fig. 9 B in the case where light source direction is constant, and video camera is seen from all angles The rim(ming) light that game object is shown when examining game object, wherein from left to right, as light source direction and camera direction are more next Closer, the range of exposures of the corresponding illumination shown is increasing, rim(ming) light (the game object performance of corresponding game object Brighter region) be always able to reflect the direction of light source, while when light source direction is consistent with camera direction (rightmost State), game object would not show rim(ming) light, and correspondence will not show the exposure of large area.
