The following are detailed below. In this embodiment, a detailed description will be given of a three-dimensional model display method, which may be integrated on a computer device, as shown in fig. 3, where fig. 3 is a flowchart of the three-dimensional model display method provided in this embodiment of the present application. The three-dimensional model display method may include:

101. and displaying a model page of the client, wherein the model page comprises a track drawing area.

The client can comprise an application program which is used for providing service for a user on computer equipment, and the client in the application can comprise an application program which can provide track drawing and three-dimensional model display functions, so that the application can be suitable for most of user-oriented clients, such as an instant messaging client, a browser client, a drawing client, an album client, an image processing client, an image shooting client, an audio and video playing client and the like.

In an actual application scene, the model page may be a single page, or a plurality of sub-pages under the model page may be set according to different application requirements, for example, the model page may include a first display sub-page and a second display sub-page of the drawn sub-pages, and different sub-pages may be switched by triggering a control (e.g., clicking a page switching button), operating a specific page (e.g., sliding a page), automatically, and the like.

The mode of displaying the model page may be various, and specifically, the mode may be specifically set according to factors such as the type of the client, for example, when the user clicks the main page displayed after entering the drawing client, the main page may be the model page, and for example, after the screenshot control of the audio/video playing client is triggered, the audio/video playing client may display the model page for the screenshot image, and the like.

The model page may include a track drawing area, where a user may draw a track in the track drawing area through a mouse, a stylus, or other devices, or through a finger, and the like, where the track drawing area may be a blank background board, and may also include basic display contents such as an image, an existing two-dimensional track, an existing three-dimensional model, and the like.

In order to adapt to the personalized requirements of users, the number of the trajectory rendering regions in the model page can be flexibly adjusted, for example, in order to match scenes commonly rendered by multiple persons, one trajectory rendering region can be allocated to each participant in the model page according to the number of participants participating in the common rendering in the model page.

The shape of the trajectory drawing area may include a plurality of shapes, for example, when the client is a graffiti drawing client facing children, in order to increase interest, the trajectory drawing area whose outline is a specific animal may be displayed, for example, a user wants to achieve an object of improving basic display content by displaying a target three-dimensional model on the basic display content, the shape and position of the trajectory drawing area may be set to match the shape and position of the target three-dimensional model that the user wants to display, specifically, the user may draw the trajectory drawing area on a model page, or may preset a plurality of selectable trajectory drawing areas in specific positions and shapes, so that one of the selectable trajectory drawing areas may be directly selected during use.

For example, referring to FIG. 4, a client-displayed model page 10 may include a trajectory-drawing region 101.

102. And responding to the drawing operation in the track drawing area, determining a target two-dimensional track coordinate set corresponding to the drawing operation, and displaying the target two-dimensional track on the model page based on the target two-dimensional track coordinate set.

The drawing operation may include an operation of a user in a trajectory drawing area of the client, the drawing operation may be a process, the process may last for a period of time, and the client may identify and record the process of the drawing operation at a set time interval, so as to obtain a target two-dimensional trajectory coordinate set corresponding to the drawing operation.

In the present application, in response to a condition or state that may be used to indicate that the executed operation depends on, when the dependent condition or state is satisfied, one or more of the executed operations may be in real time or may have a set delay; there is no restriction on the order of execution of the operations performed unless otherwise specified.

Specifically, with the difference of the computer devices to which the clients belong, in response to the drawing operation in the trajectory drawing area, it is determined that the target two-dimensional trajectory coordinate set corresponding to the drawing operation may change accordingly, for example, the drawing operation of dragging a mouse and the drawing operation of sliding a finger on a screen, the modes of responding to the drawing operation and determining the target two-dimensional trajectory coordinate set are not the same, and specifically, the modes may be flexibly adjusted in the actual application process, and are not described herein again.

Then, displaying the target two-dimensional track on the model page based on the target two-dimensional track coordinate set, determining the display position information of each two-dimensional track coordinate in the target two-dimensional track coordinate set on the model page, connecting the display position information according to the sequence information of the two-dimensional track coordinates to obtain the target two-dimensional track, and displaying the target two-dimensional track on the model page.

The model page may further include a trajectory display area, the target two-dimensional trajectory may be displayed in the trajectory display area, a display position, a display duty and the like of the trajectory display area on the model page may be flexibly set according to an actual situation, for example, the trajectory display area and the trajectory drawing area may be overlapped areas, or for example, the trajectory display area may be multiple areas, and the trajectory display area may be above and below the trajectory drawing area, and the like.

In order to increase the display effect, when the target two-dimensional track is displayed on the model page, the target two-dimensional track can be displayed by combining the dynamic effect, the sound effect, the dynamic image and the like, for example, the target two-dimensional track is displayed and the animation effect of putting fireworks is matched; when the target two-dimensional trajectory itself is displayed, the target two-dimensional trajectory may also be displayed in a dynamic and effective manner, for example, a drawing process of the target two-dimensional trajectory may be "reproduced" during displaying, that is, the whole target two-dimensional trajectory is gradually and completely displayed from a starting point of displaying the target two-dimensional trajectory.

For example, referring to fig. 4, in response to a drawing operation by a user in the trajectory drawing area 101 of the model page 10, the client determines a target two-dimensional trajectory coordinate set corresponding to the drawing operation, and displays a target two-dimensional trajectory x1 on the model page 20 based on the target two-dimensional trajectory coordinate set.

In some embodiments, the step "in response to a drawing operation within the trajectory drawing region, determining a target two-dimensional trajectory coordinate set corresponding to the drawing operation, and displaying the target two-dimensional trajectory on the model page based on the target two-dimensional trajectory coordinate set" may include:

responding to the operation aiming at the track drawing area, determining an initial two-dimensional track coordinate set, displaying an initial two-dimensional track on a model page based on the initial two-dimensional track coordinate set, wherein the model page further comprises a track conversion selection control of the initial two-dimensional track; responding to the trigger operation of selecting a control for track conversion, and converting the initial two-dimensional track based on the initial two-dimensional track coordinate set to obtain a target two-dimensional track coordinate set; and displaying the target two-dimensional track on the model page based on the target two-dimensional track coordinate set.

In an application scenario, due to the difficulty of drawing operation, or the user himself or herself, a two-dimensional trajectory obtained by the user through drawing may not be effective, for example, the user wants to obtain a standard circle, and the circle obtained by the user drawing is usually poor in smoothness of lines and not very standard.

Therefore, in order to enhance the display effect, the display interest is improved, and the personalized requirements of the user are met, the track drawn by the user can be optimized, the target two-dimensional track which is more attractive or meets the use requirements of the user is obtained, and then the target three-dimensional model corresponding to the target two-dimensional track is obtained.

The initial two-dimensional track coordinate set may include a set of two-dimensional track coordinates acquired in a drawing operation process, the initial two-dimensional track may include a track actually drawn by a user, and the target two-dimensional track may include a track obtained by converting the initial two-dimensional track.

The track conversion selection control can comprise a plurality of buttons, controls, text boxes and the like, the conversion direction of the initial two-dimensional track can be determined through the track conversion selection control, and the client is triggered to convert the initial two-dimensional track coordinate set of the initial two-dimensional track to obtain the target two-dimensional track coordinate set of the target two-dimensional track. The conversion direction of the track conversion can be various, and the smooth operation is performed on the curve, such as converting a circle drawn by a user into a standard circle; a straightening operation for a curve or a straight line, such as converting a straight line drawn by a user into a horizontal standard straight line; rich operations for curves or lines, such as converting a user-drawn semicircle into a meniscus shape, converting a user-drawn curve into a flower shape, etc., wherein a standard figure (e.g., a standard circle or a standard line) may be understood as a more accurate figure that can only be obtained by drawing software or a specialized drawing tool.

When displaying, the initial two-dimensional track and the target two-dimensional track may be sequentially displayed on the model page, and in addition, only the target two-dimensional track may be displayed on the model page, and specifically, the processing may be flexibly performed according to the actual application scenario.

For example, referring to fig. 5, in response to a user operating on the trajectory drawing area, an initial two-dimensional trajectory coordinate set 1 is determined, and an initial two-dimensional trajectory c1 is displayed on the model page 40 based on the initial two-dimensional trajectory coordinate set 1, where the model page 40 further includes a trajectory conversion selection control 401 of the initial two-dimensional trajectory; in response to the click operation of the user on the track conversion selection control 401, the initial two-dimensional track is converted based on the initial two-dimensional track coordinate set 1 to obtain a target two-dimensional track coordinate set 1, and the target two-dimensional track c2 obtained through the target two-dimensional track coordinate set 1 is displayed on the model page 40.

In some embodiments, the step "in response to a trigger operation for selecting a control for trajectory conversion, converting the initial two-dimensional trajectory based on the initial two-dimensional trajectory coordinate set to obtain the target two-dimensional trajectory coordinate set" may include:

determining a track conversion strategy of the initial two-dimensional track in response to a trigger operation for selecting a control for track conversion; and converting the initial two-dimensional track based on a track conversion strategy and the initial two-dimensional track coordinate set to obtain a target two-dimensional track coordinate set.

Specifically, the trajectory transformation strategy may correspond to a transformation direction of the initial two-dimensional trajectory, and the transformation direction corresponds to a specific transformation strategy, for example, a curve is transformed into a standard circular trajectory transformation strategy 1, and the curve is transformed into a standard straight line trajectory transformation strategy 2.

One track conversion selection control may correspond to one conversion direction and, in turn, one track conversion strategy. When displayed, the track conversion selection control can select a sub-button, a conversion selection frame and the like for a plurality of conversions.

For example, the trajectory transformation selection control of the model page may include 3 sub-controls, which are a smooth button, a straightening button, and a rich button, respectively, and for example, the trajectory transformation control of the model page may be a selection box and a determination button, and the selection box may include a smooth option, a straightening option, and a rich option.

In some embodiments, the step of "converting the initial two-dimensional trajectory based on the trajectory conversion policy and the initial two-dimensional trajectory coordinate set to obtain the target two-dimensional trajectory coordinate set" may include:

determining Bessel control coordinate points of the initial two-dimensional track based on the track conversion strategy and the initial two-dimensional track coordinate set; and generating a Bezier curve coordinate set of the Bezier curve through the Bezier control coordinate points of the initial two-dimensional track to obtain a target two-dimensional track coordinate set.

In the process of conversion through the trajectory conversion strategy, the curve can be developed based on the bezier curve, for example, when the curve is subjected to smoothing processing, the curve can be divided into multiple sections, bezier control coordinate points on each section are determined, then multiple sections of bezier curves are generated according to two end points and the bezier control coordinate points of each section of the curve, a target two-dimensional trajectory can be obtained based on the multiple sections of bezier curves, and a target two-dimensional trajectory coordinate set of the target two-dimensional trajectory is determined.

103. And displaying a target three-dimensional model corresponding to the target two-dimensional track on a model page through a three-dimensional engine based on the target two-dimensional track coordinate set.

The three-dimensional engine may include a library in which a plurality of interfaces are encapsulated, a three-dimensional model may be generated and rendered by the three-dimensional engine, and the functions of the three-dimensional engine may also be adjusted according to differences in usage requirements, which is not described herein again. A common three-dimensional engine, such as babylon (js), processes a target two-dimensional trajectory coordinate set of a target two-dimensional trajectory through the three-dimensional engine, generates a target three-dimensional model corresponding to the target two-dimensional trajectory, and renders the target three-dimensional model on a model page to display the target three-dimensional model.

For example, referring to FIG. 4, the generated target three-dimensional model x2 is displayed on the model page 30 by the three-dimensional engine based on the target two-dimensional trajectory coordinate set.

In some embodiments, the model page further includes a model template selection control, and the step of displaying, by the three-dimensional engine, the target three-dimensional model corresponding to the target two-dimensional trajectory on the model page based on the target two-dimensional trajectory coordinate set may include:

responding to the trigger operation of selecting a control for the model template, and determining a target model template corresponding to the target two-dimensional track; and displaying a target three-dimensional model corresponding to the target two-dimensional track on a model page through a three-dimensional engine based on the target two-dimensional track coordinate set and the target model template.

For example, when the target two-dimensional track is a straight line, the corresponding three-dimensional model may include any three-dimensional object containing straight line elements, such as a three-dimensional cylindrical object (e.g., a pipe, a trunk, a bottle), a three-dimensional cubic object (e.g., a wall, a partition, a mobile phone, a shutter, a notebook), and the like.

In the application, a target model template of a target two-dimensional track can be determined through a model template selection control, and then a target three-dimensional model is generated through a three-dimensional engine, the model template selection control can comprise buttons, text boxes and the like, and the number of the model template selection controls can comprise a plurality of template selection sub-controls or template selection boxes and the like.

After the target model template is determined based on the operation of the user for selecting the control for the model template, a target three-dimensional model corresponding to the target two-dimensional track can be generated and rendered on a model page to display according to the three-dimensional engine based on the target two-dimensional track coordinate set and the target model template.

For example, referring to fig. 6, the model page 50 further includes a model template selection control 501, and in response to a user's trigger operation on the model template selection control 501, a target model template selected by the user is determined, a target three-dimensional model matching the target model template is generated by the three-dimensional engine, and the target three-dimensional model x2 is displayed on the model page 30.

In some embodiments, the model page further includes a model material selection control, and the step of displaying, by the three-dimensional engine, the target three-dimensional model corresponding to the target two-dimensional trajectory on the model page based on the target two-dimensional trajectory coordinate set and the target model template may include:

determining a target model material corresponding to the target two-dimensional track in response to a trigger operation for selecting a control according to the model material; and displaying a target three-dimensional model corresponding to the target two-dimensional track on a model page through a three-dimensional engine based on the target two-dimensional track coordinate set, the target model template and the target model material.

After the model template of the target three-dimensional model is determined, the model material of the target three-dimensional model can be selected, wherein the model material can comprise pattern patterns, patterns and the like on the surface of the target three-dimensional model, the target model template can determine the three-dimensional shape of the target three-dimensional model, and the target model material can have three-dimensional effects such as surface patterns and the like of the target three-dimensional model.

The target model material may be associated with the target model template, and then the target model material may be selected after the target model template is determined, for example, after the target model template is determined to be a trunk, the model material selection control may provide different trunk textures, so that the user may determine the target model material therefrom.

The target model material can be independent from the target model template, in this case, the selection sequence of the model template and the model material is not limited, the model material selection control and the model template selection control can be displayed in sequence, the model material selection control and the model template selection control can also be displayed simultaneously, and particularly, the model material selection control and the model template selection control can be flexibly selected in an actual application scene.

After the target model material selected by the user is determined, a target three-dimensional model can be generated and rendered on a model page according to a three-dimensional engine based on a target two-dimensional trajectory coordinate set, a target model template and the target model material to display the target three-dimensional model.

For example, referring to fig. 7, the model page 60 further includes a model material selection control 601, and in response to a user's trigger operation on the model material selection control 601, a target model material selected by the user is determined, a target three-dimensional model matching the target model template and the target model material is generated by the three-dimensional engine, and the target three-dimensional model x2 is displayed on the model page 30.

In some embodiments, the step of displaying, by the three-dimensional engine, the target three-dimensional model corresponding to the target two-dimensional trajectory on the model page based on the target two-dimensional trajectory coordinate set may include:

In some embodiments, the step of displaying, by the three-dimensional engine, the target three-dimensional model corresponding to the target two-dimensional trajectory on the model page based on the target two-dimensional trajectory coordinate set, the target model template, and the target model material may include:

converting a target two-dimensional coordinate in the target two-dimensional track coordinate set according to the target model template to obtain a target three-dimensional coordinate set; and displaying a target three-dimensional model corresponding to the target two-dimensional track on a model page through a three-dimensional engine based on the target three-dimensional coordinate set, the target model template and the target model material.

Determining a coordinate point on a plane needs to use a two-dimensional coordinate system, and determining a coordinate point in a three-dimensional space needs to use a three-dimensional coordinate system, so that a target two-dimensional track coordinate set for describing a target two-dimensional track needs to be converted at first when a target three-dimensional model is displayed, the target two-dimensional track coordinate set comprises a plurality of target two-dimensional coordinates, each target two-dimensional coordinate is converted into a three-dimensional coordinate, and the target three-dimensional coordinate set is obtained based on all three-dimensional coordinates. Then, the target three-dimensional model can be displayed on the model page according to the target three-dimensional coordinate set, the target model template and the target model material.

determining a coordinate transformation strategy corresponding to the target model template; and respectively converting the target two-dimensional coordinates in the target two-dimensional track coordinate set into corresponding target three-dimensional coordinates based on a coordinate transformation strategy so as to obtain a target three-dimensional coordinate set.

Specifically, the target model template indicates a shape of the target three-dimensional model, and the target three-dimensional coordinate set describes the shape of the target three-dimensional model, so that the process of obtaining the target three-dimensional coordinate set through transformation may be performed based on the target model template, for example, when the target model template of the target two-dimensional trajectory is a wall, the coordinate transformation policy of the target two-dimensional trajectory may be: and generating two target three-dimensional coordinates by using one target two-dimensional coordinate, wherein the number of the target three-dimensional coordinates in the target three-dimensional coordinate set finally obtained by the change strategy is twice of the target two-dimensional coordinates in the target two-dimensional track coordinate set.

In addition, when an application scene without a model template exists, the coordinate transformation strategy can also be set by a user, which is equivalent to that the user determines the shape of the target three-dimensional model by setting the coordinate transformation strategy, specifically, a control can be set on a model page, and prompt information and the like can be set around the control.

For example, a coordinate transformation strategy a corresponding to the target model template 1 may be determined, and based on the coordinate transformation strategy a, the target two-dimensional coordinates in the target two-dimensional trajectory coordinate set are transformed to obtain at least one target three-dimensional coordinate corresponding thereto, so as to obtain the target three-dimensional coordinate set 1.

calling a target model creating interface in a three-dimensional engine based on a target three-dimensional coordinate set, a target model template and a target model material to generate a target three-dimensional model corresponding to a target two-dimensional track; and displaying the target three-dimensional model on the model page.

Specifically, the process of generating the target three-dimensional model by the three-dimensional engine includes calling a specific interface from the target three-dimensional engine, and implementing the processes of shape molding, material addition and the like of the target three-dimensional model by the interface, and the processes may have differences in different three-dimensional engines, for example, in babylon.
