It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0025] This method embodiment can be executed on a mobile terminal, computer terminal, or similar computing device. Taking running on a mobile terminal as an example, the mobile terminal can be a smartphone (such as an Android phone, iOS phone, etc.), tablet computer, PDA, mobile Internet Device (MID), PAD, game console, and other terminal devices. Figure 1 This is a hardware structure block diagram of a mobile terminal for a method of generating a shattering animation according to an embodiment of the present invention. For example... Figure 1 As shown, a mobile terminal may include one or more ( Figure 1Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a central processing unit (CPU), graphics processing unit (GPU), digital signal processing (DSP) chip, microprocessor (MCU), programmable logic device (FPGA), neural network processor (NPU), tensor processor (TPU), artificial intelligence (AI) type processor, etc.) and a memory 104 for storing data are also shown. Optionally, the mobile terminal may further include a transmission device 106 for communication functions, an input / output device 108, and a display device 110.

For example, the mobile terminal may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0026] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the method for generating the shattering animation in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby realizing the aforementioned method for generating the shattering animation. The memory 104 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

[0030] In one embodiment of this disclosure, the method for generating a shattering animation can run on a local terminal device or a server. When the method for generating a shattering animation runs on a server, the method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system includes a server and client devices.

[0031] In one possible implementation, embodiments of the present invention provide a method for generating a shattering animation. Figure 2 This is a flowchart of the generation of a three-dimensional fragmentation animation according to one embodiment of the present invention, such as... Figure 2 As shown, the method includes the following steps:

[0032] Step S202: Obtain the crack texture and target model.

[0033] Specifically, the crack texture mentioned above can be a crack pattern of fragile items, such as the crack pattern of broken glass or broken crystal. The target model corresponds to the 3D model of the crack texture. For example, if the crack texture is a glass crack texture, the target model can be a glass model. It should be noted that this glass model can be a model of a single piece of glass, or a model of a glass object, such as a wine glass or a tabletop.

[0034] As an alternative implementation, if the target model is a glass model of a piece of glass, the target model can be as follows: Figure 3 As shown.

[0035] Optionally, generating the crack texture map corresponding to the 3D shattering animation includes: constructing cracks in different directions to generate an initial texture map; and applying lighting processing to the initial texture map to obtain the crack texture map. For example, after determining the desired 3D shattering animation, firstly, crack textures in different directions are constructed according to the desired 3D shattering animation, resulting in... Figure 4A The initial texture shown is as follows: Figure 4A As shown, Figure 4A The white lines are used to represent the cracks that have been drawn.

[0036] Optionally, the initial texture is subjected to lighting processing to obtain a crack texture, including: determining a target fragment of a preset shape in the initial texture; and applying lighting processing to a portion of the area where the target fragment is located to obtain the crack texture. Here, the fragment in the initial texture refers to an area composed of cracks in different directions. The preset shape can be a shape preset by the artists.

[0037] As an optional implementation, after obtaining the initial texture, lighting processing is applied to the initial texture to add lighting effects and enhance the three-dimensionality of the crack texture, such as... Figure 4B As shown, Figure 4B The lower half is the section where lighting effects have been added. Figure 4B The upper part is the initial texture without lighting effects. Figure 4A After adding lighting effects to all the initial textures shown, the result is as follows: Figure 4C The crack texture shown.

[0038] Step S204: Cut the target model based on the crack map to obtain the fragment model.

[0039] In one alternative embodiment, the target model can be cut according to the direction of the crack in the crack map to obtain multiple fragment models.

[0040] Step S206: Perform texture sampling on the target model and the fragment model respectively to obtain the first texture coordinates corresponding to the target model and the second texture coordinates corresponding to the fragment model.

[0041] In an optional embodiment, the first texture coordinates corresponding to the target model are used to characterize the UV coordinates corresponding to the target model, and the second texture coordinates corresponding to the fragment model are used to characterize the UV coordinates of the fragment model.

[0042] As an optional implementation, after obtaining the target model and the fragment model, glass texture sampling can be performed on the fragment model to obtain, as shown below. Figure 5 The texture map of the glass fragments shown. Figure 5 Irregular small fragments are used to represent the texture of the fragment model. Furthermore, texture sampling can also be performed on the target model to obtain, for example... Figure 6 The texture map of the target model shown.

[0043] Step S208: Generate a 3D shattering animation based on the crack map, the first texture coordinates, and the second texture coordinates.

[0044] As an optional implementation, the crack map can be texture-sampled using the first texture coordinates to obtain the color of the R channel of the crack map, i.e., the first preset channel color. This R channel color can be used as the self-illumination color of the fragment model. Alternatively, a preset ablation map can be texture-sampled using the second texture coordinates to obtain the color of the R channel of the preset ablation map, i.e., the second preset channel color. Furthermore, a preset refraction map (Noise) can be texture-sampled based on the first texture coordinates to obtain the color of the R channel of the preset refraction map, i.e., the third channel color. After obtaining the R channel color of the preset ablation map, the second channel color can be processed using the ablation function MF_Dissolve to obtain the ablation result MF_DissolveResult. Subsequently, the first channel color is multiplied by the ablation result MF_DissolveResult to obtain the product of the first channel color and the ablation result MF_DissolveResult, which is used as the opacity of the fragment model, i.e., the first target color.

[0045] Then, the product of the ablation result MF_DissolveResult and the third channel color is obtained to get the second target color, which can be used as the refraction of the fragment model.

[0046] Finally, vertex animation processing is performed on the fragment model based on the texture color, the first target color, the second target color, the second texture coordinates, and the offset degree to obtain a 3D fragmentation animation.

[0047] As an optional implementation, the three-dimensional fragmentation animation generated using the method provided by this invention can, as... Figure 7 As shown, it achieves a good three-dimensional art effect.

[0048] In the above embodiments of the present invention, after obtaining the crack map and the target model, the target model is cut based on the crack map to obtain a three-dimensional fragment model, which can make the subsequently generated three-dimensional fragmentation animation more realistic. Subsequently, the target model and the fragment model are sampled to obtain the first texture coordinates and the second texture coordinates. Finally, the crack map, the first texture coordinates and the second texture coordinates are rendered to obtain a more three-dimensional fragmentation animation, which achieves the technical effect of improving the user experience and solves the technical problem of poor fragmentation effect display in the prior art, resulting in a poor user experience.

[0049] Optionally, a 3D fragmentation animation is generated based on the crack map, the first texture coordinates, and the second texture coordinates, including: performing texture sampling on the crack map using the first texture coordinates to obtain the texture color of the crack map; and performing vertex animation processing on the fragment model based on the texture color and the second texture coordinates to obtain the 3D fragmentation animation.

[0050] As an optional implementation, the texture color can be the color of the R channel obtained by sampling the crack texture using the first texture coordinates, and the texture color can be used as the self-illuminating color of the fragment model.

[0051] In the above optional embodiments, texture sampling is performed based on the first texture coordinates and the crack map to obtain the texture color, which facilitates subsequent vertex animation processing based on the texture color and the second texture coordinates, thereby improving the generation efficiency of the 3D shattering animation.

[0052] Optionally, vertex animation processing is performed on the fragment model based on texture color and second texture coordinates to obtain a 3D fragmentation animation, including: obtaining the degree of control offset, wherein the degree of control offset is used to control the degree of offset of the fragment model; and vertex animation processing is performed on the fragment model based on texture color, second texture coordinates and control offset to obtain a 3D fragmentation animation.

[0053] As an optional implementation, the aforementioned control offset can be a WPO (World Position Offset) parameter, and can be used as the global position offset of the fragment model.

[0054] Optionally, vertex animation processing is performed on the fragment model based on texture color, second texture coordinates, and offset degree to obtain a 3D fragmentation animation, including: texture sampling of the crack map using the first texture coordinates to obtain a first channel color, wherein the first channel color is the color of the first preset channel of the crack map; texture sampling of a preset ablation map using the second texture coordinates to obtain a second channel color, wherein the second channel color is the color of the second preset channel of the preset ablation map; processing the second channel color using an ablation function to generate an ablation result; obtaining the product of the ablation result and the first channel color to obtain a first target color; and vertex animation processing is performed on the fragment model based on texture color, first target color, second texture coordinates, and offset degree to obtain a 3D fragmentation animation.

[0055] As an optional implementation, the first and second preset channels can be R channels. The ablation map can be a map used to control the ablation effect. The first target color can be used as the opacity of the fragment model.

[0056] Optionally, vertex animation processing is performed on the fragment model based on the texture color, the first target color, the second texture coordinates, and the offset degree to obtain a 3D fragmentation animation, including: performing texture sampling on a preset refraction map based on the first texture coordinates to obtain a third channel color, wherein the third channel color is the color of the third preset channel of the preset refraction map; obtaining the product of the ablation result and the third channel color to obtain the second target color; and performing vertex animation processing on the fragment model based on the texture color, the first target color, the second target color, the second texture coordinates, and the offset degree to obtain a 3D fragmentation animation.

[0057] As an optional implementation, the third preset channel is the R channel. The preset refraction map is used to preserve the grayscale information of the model and to calculate the refraction of the fragment model. The second target color can be used as the refraction of the fragment model.

[0058] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.
