In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as presented in the figures, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. Every other embodiment that can be obtained by a person skilled in the art without making creative efforts based on the embodiments of the present application falls within the protection scope of the present application.

Research shows that in a game, in order to simulate a picture with a dynamic effect, the mode of producing special effect animation is usually selected to realize the simulation. The simulation of the dynamic effect is realized by the special effect animation mode, a large number of particles are needed to be used by calling a relevant model, and a multi-frame special effect picture needs to be made to realize the conversion of the change style along with the continuous change of the dynamic effect. In the process of rendering, along with the increase of the number of the special effect pictures, the calculation examples consumed by the terminal equipment are increased, when the rendering is performed in the way, the requirement on the performance of the terminal equipment is extremely high, and due to the fact that the number of the special effect pictures is large, the time consumed by the terminal equipment for rendering is long, and the rendering rate is low.

Based on this, the embodiment of the application provides a model rendering method with a dynamic effect, which can render a target model with a dynamic effect through the change of a transparency parameter carried by a target material ball with time, so that on the premise of ensuring the authenticity of a rendered object to be simulated, the number of calculations consumed in the rendering process of a terminal device can be reduced, and the rendering efficiency of a game picture is improved.

Referring to fig. 1, fig. 1 is a flowchart illustrating a model rendering method for dynamic effects according to an embodiment of the present disclosure. As shown in fig. 1, a method for rendering a dynamic effect model provided in an embodiment of the present application includes:

s101, obtaining an initial transparency parameter of the initial material ball according to the material information of the target model.

S102, adjusting an initial transparency parameter of the initial material ball based on the pixel parameter of the texture map to obtain a target material ball with the transparency parameter changing along with time.

S103, rendering the target model by using the target material ball to obtain a dynamic effect of the target model.

The embodiment of the application provides a model rendering method of a dynamic effect, when a target model displayed in a game scene has the dynamic effect, acquiring an initial transparency parameter of a material ball for rendering the target model according to material information when the target model is displayed; in order to render a target model with a dynamic effect, the initial transparency parameter in the initial material ball is adjusted through a dynamic texture mapping for rendering the dynamic effect on the surface texture of the target model, and because the transparency parameter of the dynamic texture mapping changes along with time, the transparency parameter carried by the adjusted target material ball can also change along with time, and further, the dynamic effect of the target model is simulated. Therefore, the target model with the dynamic effect can be simulated without additionally manufacturing the animation special effect, so that the consumption of terminal equipment for rendering special effect pictures can be reduced, and the rendering efficiency of the terminal equipment is improved.

If a target model with a real effect is simulated in a game, the material of the target model needs to be simulated; here, the material means real attributes of the target object, for example, color information, reflection effect, transparency information, and the like of the target object.

The texture ball is a VR parameter file, which includes the color parameters, the light reflection effect, the transparency parameters, and other physical property parameters of the target model, and also includes various static maps, such as texture maps, Material Capture maps, and normal maps, so that what effect the texture ball can actually render depends on the physical property parameters and various map information included in the texture map.

In step S101, an initial transparency parameter of an initial material ball used for rendering the target model may be obtained in advance according to material information exhibited by the target model in the game scene.

Here, while obtaining the initial transparency parameter, the method may further set other initial parameters in the initial material ball by referring to the material information of the target model, and specifically may include parameters such as an initial color parameter, a reflection effect parameter, and an initial transparency parameter.

For example, here, taking the target model as "moon" as an example, in order to make the displayed "moon" more beautiful and fit to the display effect of the real "moon" in the game, the "moon" is usually made to present a semi-transparent state, that is, the outer contour of the "moon" is an opaque boundary, and the inside of the "moon" is a completely transparent state.

Since the object model with the dynamic effect is obtained by rendering in a manner that the transparency parameter changes with time in the application, other parameters (for example, color parameters) are not changed in the process of adjusting the transparency, and the other parameters can be directly added to the material ball under the condition that the parameters are not changed in the process of adjusting the transparency, so that only the adjusting process of the transparency is explained in the subsequent process, and the adding process of the other parameters is not repeated.

The above process can only render a statically displayed target model, and in some game scenes, in order to improve the reality of the game picture, some dynamic effects are usually present on the target model, for example, "smoke" floats on the surface of the "moon" and the like.

In step S102, in order to obtain an object model with a dynamic effect, an initial transparency parameter of an initial material ball is adjusted by using a pixel parameter of a texture map, so that the transparency parameter in the adjusted material ball changes with time; therefore, the dynamic effect can be simulated by changing the transparency parameter along with the time, and special effect animation does not need to be additionally made to realize the dynamic effect.

The texture mapping comprises a dynamic texture mapping, and pixel parameters in the dynamic texture mapping change along with time; the dynamic texture map is used for rendering dynamic effects on the surface texture of the target model.

Further, for an object model, the surface texture of the object model not only includes dynamic effects, but also includes some predetermined patterns (e.g., foreground patterns and background patterns) displayed fixedly; however, if the object model is in a completely transparent state, no pattern can be displayed on the surface texture of the object model, and only in a non-transparent state, such as an opaque or partially opaque state, the non-transparent region can display the corresponding pattern.

Therefore, in order to enable the surface texture of the rendered target model to display a corresponding pattern, the initial transparency of the initial material ball used for rendering the target model may be adjusted according to the first pixel parameter of the static texture map, so as to ensure that the static texture map presents a non-transparent state at the corresponding display area in the target model.

In one embodiment, the texture map further comprises a static texture map; referring to fig. 2, fig. 2 is a schematic diagram illustrating a transparency adjustment process according to an embodiment of the present disclosure. As shown in fig. 2, step S102 includes:

and S1021, adjusting the initial transparency parameter of the initial material ball by using the first pixel parameter of the static texture mapping to obtain the first material ball with the first transparency parameter.

In the step, the adjustment of the initial transparency parameter of the initial material ball is gradually completed by utilizing the static texture mapping and the dynamic texture mapping respectively; specifically, adjusting an initial transparency parameter of an initial material ball by using a first pixel parameter carried by a static texture mapping; here, for a static texture map, it is composed of a plurality of polygon meshes, each polygon mesh is equivalent to a pixel position (point) of the static texture map, each pixel position has a first pixel value, when adjusting the initial transparency parameter, the first pixel value of each pixel position can be used to adjust the transparency value at the corresponding pixel position in the initial texture sphere; and then obtaining the first material ball with the first transparency parameter after adjustment.

Since the transparency is actually a value between 0 and 1, changing the value to be within the range of 0 to 1 and not 0 can change the transparency of each pixel position, so that the pixel position which is originally completely transparent can be changed into an opaque or semitransparent state;

the first pixel parameters of the static texture map, for example, the pixel value of any color channel, or the transparency parameter carried by itself, or the gray level pixel value, etc., are all a "numerical value" within a range of 0 to 1, and thus, the first pixel parameters herein may include a color parameter and a transparency parameter (Alpha, a); the color parameters may include color parameters of three color channels of Red (Red, R), Green (Green, G), and Blue (Blue, B), and grayscale pixel parameters, etc.

In one embodiment, the static texture map comprises a foreground pattern map; step S1021 includes: determining a transparent area and a non-transparent area in the initial material ball according to the surface texture of the target model; and adjusting the initial transparency parameter of the non-transparent area by using the first pixel parameter of the foreground pattern map to obtain a first material ball with a first transparency parameter.

The foreground pattern map is used for rendering foreground patterns in the surface texture of the target model, and the foreground pattern map can be displayed on the surface of the target model obtained through rendering of the material ball by adding the foreground pattern map into the material ball.

In the step, for the target model, a transparent area and a non-transparent area exist in the surface texture of the target model, namely, no pattern needs to be displayed in the transparent area of the surface texture of the target model; as long as it is ensured that the non-transparent region can display the foreground pattern map, therefore, in order to reduce a part of data processing amount, only the foreground pattern map is needed to be used to adjust the initial transparency parameter in the non-transparent region in the initial material ball; specifically, a transparent area and a non-transparent area in the initial material ball are determined according to the surface texture when the target model is displayed; for the determined non-transparent area, adjusting the initial transparency parameter of the non-transparent area in the initial material ball by using a first pixel parameter (for example, a pixel value of any color channel, or a carried transparency parameter, or a gray pixel value, etc.) of the foreground pattern map through corresponding operation, so as to obtain the first material ball with the first transparency parameter. Here, the corresponding operation includes addition, subtraction, or, xor, inversion, and the like.

Aiming at the determined transparent area, in order to further reduce the calculated amount in the rendering process, for the transparent area, the initial transparency parameter of each pixel point in the transparent area can be adjusted by directly utilizing the preset transparency parameter and in a value assignment mode.

Corresponding to the above embodiment, it is assumed that the pattern displayed on the "moon" is "leaf", the initial material sphere for rendering the "moon" is a semi-transparent material sphere "solid outside and virtual inside" (the rendered "moon" gradually changes from the outer contour to the center from the completely opaque state to the completely transparent state), the center area of the "moon" is in the completely transparent state, and the "leaf" in the center area cannot be displayed in the completely transparent state, so the initial transparency parameter of each pixel position at the position of the "leaf" in the initial material sphere needs to be adjusted by using the first pixel parameter of the foreground pattern map corresponding to the "leaf" at this time, so that the transparency of the pixel position at the position of the "leaf" is not 0, that is, the pixel position is in the non-transparent state.

In order to enable the target model to have a more real effect, the outer ring boundary contour of the surface texture of the target model can be processed into a model with a multi-level gradient effect through multiple times of synthesis processing.

In one embodiment, the adjusting the initial transparency parameter of the initial material ball by using the first pixel parameter of the foreground pattern map to obtain the first material ball with the first transparency parameter includes:

step a, adjusting the initial transparency parameter in the nontransparent area by using the first pixel parameter of the foreground pattern map to obtain a second material ball with a second transparency parameter.

In the step, the foreground pattern map is used for adjusting the initial transparency parameter in the non-transparent area in the initial material ball to obtain a second material ball with a second transparency parameter; at this time, the target model is rendered by using the second material balls, so that the target model with the surface displaying the foreground pattern map can be obtained.

And b, synthesizing the initial material ball and the second material ball by using the first transparency difference value of each pixel position between the initial transparency parameter and the second transparency parameter to obtain a third material ball with a third transparency parameter.

After the second material ball is obtained, calculating a first transparency difference value between an initial transparency value of each pixel position in the initial transparency parameter and a second transparency value of each pixel position in the second transparency parameter, and synthesizing the initial material ball and the second material ball by using the first transparency difference value of each pixel position to obtain a third material ball with a third transparency parameter; at this time, the target model is rendered by using the third material ball, so that the target model with the boundary having the first gradual change effect and without displaying the foreground pattern map can be obtained.

Here, the first fade effect refers to an outer circle boundary contour of the object model, which gradually changes from a non-transparent state to a transparent state.

And c, performing negation treatment on the initial transparency parameter of the initial material ball to obtain a reverse material ball with a reverse transparency parameter.

In the step, the initial transparency parameter carried by the initial material ball can be subjected to negation treatment; specifically, the inverse material sphere with the inverse transparency parameter is obtained by calculating the difference between the initial transparency value at each pixel position and "1".

And d, synthesizing the second material ball and the reverse material ball by using the second transparency difference value of each pixel position between the second transparency parameter and the reverse transparency parameter to obtain a fourth material ball with a fourth transparency parameter.

In the step, after the reverse material ball is obtained, a second transparency difference value between a second transparency value of each pixel position in the second transparency parameter and a reverse transparency value of each pixel position in the reverse transparency parameter is calculated, and the second material ball and the reverse material ball are subjected to synthesis processing by using the second transparency difference value of each pixel position to obtain a fourth material ball with a fourth transparency parameter; at this time, the target model is rendered by using the fourth material ball, so that the target model with the boundary having the second gradual change effect and without displaying the foreground pattern map can be obtained.

Here, the second gradient effect refers to an outer circle boundary contour of the target model, which gradually changes from a transparent state to a non-transparent state.

And e, synthesizing the third material ball and the fourth material ball by using the first maximum transparency value of each pixel position between the third transparency parameter and the fourth transparency parameter to obtain a fifth material ball with a fifth transparency parameter.

In the step, a first transparency maximum value between a third transparency value of each pixel position in a third transparency parameter and a fourth transparency value of each pixel position in a fourth transparency parameter is calculated, and a third material ball and a fourth material ball are subjected to synthesis processing by using the first transparency maximum value of each pixel position to obtain a fifth material ball with a fifth transparency parameter; at this time, the target model is rendered by using the fifth material ball, so that the target model with the outer ring boundary contour having a multi-layer gradient effect and without displaying the foreground pattern map can be obtained.

And f, synthesizing the second material ball and the fifth material ball by using the second transparency maximum value of each pixel position between the second transparency parameter and the fifth transparency parameter to obtain the first material ball with the first transparency parameter.

In the step, a second transparency maximum value between a second transparency value of each pixel position in the second transparency parameter and a fifth transparency value of each pixel position in the fifth transparency parameter is calculated, and the second transparency maximum value of each pixel position is utilized to carry out synthesis processing on the second material ball and the fifth material ball to obtain a first material ball with the first transparency parameter; at the moment, the target model is rendered by utilizing the first material ball, so that the target model with the outer ring boundary contour having a multi-layer gradient effect and displaying the foreground pattern chartlet can be obtained.

For the target model, the environment to which the target model belongs may also have a certain influence on the display effect of the target model, for example, the lighting effect existing in the environment; in order to further increase the reality of the rendering effect, the rendered target object may be influenced by the false ambient light through the environment map, so that false illumination information may be created for the rendered target model.

For some static texture maps, they may not themselves have a transparency parameter (e.g., ambient Matcap map), i.e., there are no portions of such static texture maps (e.g., ambient Matcap map) that have different transparency values, and are completely opaque at each pixel location; at this time, the transparency parameter in the material ball cannot be adjusted according to the transparency parameter carried by the material ball, and in this case, the transparency parameter in the material ball can be adjusted by using the gray pixel value carried by the material ball or the pixel parameter of any color channel.

In another embodiment, the static texture map comprises an environment map, and the first pixel parameter comprises a gray pixel parameter and/or a pixel parameter of any color channel; step S1021 includes: and adjusting the initial transparency parameter of the initial material ball by utilizing the gray pixel parameter of the environment map or the pixel parameter of any color channel to obtain the first material ball with the first transparency parameter.

Wherein the environment map is used for rendering an environment pattern in the surface texture of the target model.

In the step, on the premise that the environment map does not have the transparency parameter, the gray pixel value of each pixel position in the environment map or the pixel parameter of any color channel or the gray pixel value of each pixel position in the environment map is selected and used, and the initial transparency parameter of the initial material ball is adjusted through corresponding operation.
