[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0062] Embodiments of the present application provide a model special effects production method, device, storage medium and electronic device.

[0063] See also Figure 1 , Figure 1 A scene diagram of a model special effects production system provided in an embodiment of the present application. The model special effects production system may include any one of the model special effects production devices provided in the embodiments of the present application. The model special effects production device may be specifically integrated in an electronic device such as a terminal or a server, wherein the terminal may be a smart phone, a tablet computer, a smart Bluetooth device, a laptop computer, or a personal computer (PC) and the server may be a single server or a server cluster composed of multiple servers.

[0064] The electronic device can obtain model special effects material, which includes a three-dimensional model and a first rendering of the three-dimensional model at a first perspective; determine particle special effects parameters to be used for the three-dimensional model; determine a first material map of the three-dimensional model based on the first rendering; and generate particle special effects of the three-dimensional model based on the particle special effects parameters and the first material map.

[0065] Among them, the above-mentioned three-dimensional model can be produced by a preset three-dimensional software (for example, 3D Max, Maya and other existing mature three-dimensional animation rendering and production software). The above-mentioned first rendering image can be obtained by rendering the three-dimensional model produced by the three-dimensional software, and the corresponding first perspective is the rendering angle of the three-dimensional model, and the selection of the rendering angle of the three-dimensional model can be achieved by adjusting the camera perspective or the camera angle in the three-dimensional software. The above-mentioned particle special effect parameters are used to characterize the properties and movement mode of the particles generated based on the above-mentioned three-dimensional model, and can include particle size, particle shape, particle density, particle life and other particle attribute parameters related to particle attributes, as well as motion force type, motion force size, force field range and other particle motion parameters related to the particle operation mode. The above-mentioned particle special effects can be motion animations of multiple or single particles, and can be used to simulate the effects of convergence and dissipation of objects.

[0066] Specifically, Figure 1 As shown, the electronic device may be configured with a preset particle effect plug-in (for example, a form particle plug-in, a Particular particle plug-in, or other existing mature particle effect production plug-ins), and the particle effect plug-in is used to produce the particle effect of the three-dimensional model, and the three-dimensional software may be installed in the electronic device. When a user wants to produce a particle effect of a three-dimensional model, the electronic device may be triggered to obtain the three-dimensional model and the first rendering of the three-dimensional model from a local or cloud device, so that the electronic device obtains the model effect material of the three-dimensional model, and after obtaining the model effect material, the electronic device may start the particle effect plug-in in response to the user's start-up operation of the particle effect plug-in, and then determine the particle effect parameters of the three-dimensional model based on the particle effect plug-in, and use the first rendering as the first material map of the three-dimensional model based on the particle effect plug-in, and then the electronic device may generate the particle effect of the three-dimensional model according to the particle effect parameters of the three-dimensional model and the first material map, and export the corresponding particle effect file.

[0067] like Figure 2 As shown, Figure 2 : is a flow chart of a model special effect production method provided in an embodiment of the present application. The specific flow of the model special effect production method can be as follows:

[0068] S101. Acquire model special effects materials, where the model special effects materials include a three-dimensional model and a first rendering of the three-dimensional model at a first viewing angle.

[0069] In this embodiment, the above-mentioned model special effect production method can be applied to an electronic device installed with a preset special effect production software (for example, After Effects and other existing mature graphics and video processing software), and the special effect production software is used to produce special effects of a three-dimensional model, wherein the special effects are not limited to particle effects, and can also include luminous effects, shadow effects, halo effects or sharpening effects, etc. The above-mentioned model special effect material can be produced by material production software (for example, 3D Max, Maya and other existing mature three-dimensional animation rendering and production software), and the above-mentioned material production software and the above-mentioned special effect production software can be installed in the same electronic device, or in different electronic devices.

[0070] Specifically, the above-mentioned first rendering image can be obtained by rendering the three-dimensional model produced by the above-mentioned material production software, and the corresponding first perspective can be the rendering angle of the three-dimensional model, and in the above-mentioned material production software, the rendering angle of the three-dimensional model can be selected by adjusting the camera perspective or the camera angle.

[0071] For the convenience of description and understanding, the embodiment of the present application is described by taking the material production software and the special effect production software installed in the same electronic device as an example. Specifically, the user can make a three-dimensional model in the above-mentioned material production software in advance, and by rendering the three-dimensional model, obtain multiple two-dimensional renderings of the three-dimensional model at different perspectives (for example, the first rendering of the three-dimensional model at the first perspective, the second rendering of the three-dimensional model at the second perspective, etc.), and then the three-dimensional model and its two-dimensional renderings can be stored in the local storage or cloud storage in common model formats such as FBX or OBJ, and common image formats such as JPG or PNG. Afterwards, when the user wants to make particle special effects for the three-dimensional model, the above-mentioned electronic device can be triggered to obtain the three-dimensional model and at least one two-dimensional rendering from the local or cloud, so that the electronic device obtains the model special effect material of the three-dimensional model. Moreover, in specific implementation, the user can trigger the electronic device to display the special effect production interface by starting the special effect production software installed in the above-mentioned electronic device. For example, taking the special effect production software as After Effects as an example, the corresponding special effect production interface can be as follows Figure 3As shown, the electronic device can then respond to the user's model special effect material import operation on the special effect production interface, obtain the 3D model selected by the user and at least one 2D rendering of the 3D model from the local or cloud, and obtain the model special effect material. The specific implementation of the import operation can refer to the operation of importing models, images and other files in After Effects, so it will not be repeated here.

[0072] S102. Determine particle special effect parameters of the three-dimensional model.

[0073] Specifically, the above-mentioned particle special effects parameters can be used to characterize the properties and movement modes of particles generated based on the above-mentioned three-dimensional model in subsequent steps, which may specifically include particle attribute parameters related to particle attributes such as particle size, particle shape, particle density, and particle lifespan, as well as particle motion parameters related to particle movement such as motion force type, motion force magnitude, and force field range.

[0074] In one embodiment, Figure 4 As shown, the above S102 may specifically include:

[0075] S1021. In response to a start-up operation on a preset particle special effect plug-in, the particle special effect plug-in is started to display a special effect parameter setting interface.

[0076] Specifically, the electronic device may be configured with a preset particle effect plug-in (e.g., a form particle plug-in, a Particular particle plug-in, or other existing mature particle effect production plug-ins), and the particle effect plug-in may be called by the special effect production software to produce the particle effect of the three-dimensional model. Furthermore, during specific implementation, the electronic device may respond to the user's start-up operation of the preset particle effect plug-in on the special effect production interface, and call and start the particle effect plug-in through the special effect production interface to display the corresponding special effect parameter setting interface. For example, taking the particle effect plug-in as a form particle plug-in as an example, the corresponding special effect parameter setting interface may be as follows: Figure 5 As shown, the specific implementation method of the user's startup operation of the particle special effect plug-in can refer to the operation of starting the particle special effect plug-in in After Effects, so it will not be repeated here.

[0077] S1022. In response to the identification operation of the three-dimensional model on the special effect parameter setting interface, determine the particle special effect parameters to be used for the three-dimensional model based on the special effect parameter setting interface.

[0078] Specifically, Figure 5As shown, the above special effect parameter setting interface may include multiple particle special effect parameter groups 51 (for example, "basic form (Master)", "particle (Master)", "shadow (Master)", "layer map (Master)", etc.), and each particle special effect parameter group 51 may include multiple particle special effect parameters, for example, Figure 6 As shown in FIG. 1 , the particle effect parameter group “Master” may include a plurality of particle effect parameters for characterizing the basic form, size, position, rotation and other properties of the particle system. Figure 6 As shown, the user can change the value of the particle special effect parameter 61 "Basic form" to the OBJ model on the special effect parameter setting interface, and select the file of the above-mentioned three-dimensional model (for example, the model file with the file name "hua2") when setting the value of the particle special effect parameter 63 "3D model" to complete the identification operation of the three-dimensional model on the above-mentioned special effect parameter setting interface, so that the above-mentioned electronic device can respond to the identification operation, obtain the particle special effect parameters contained in the current special effect parameter setting interface, and obtain the particle special effect parameters to be used for the above-mentioned three-dimensional model.

[0079] In a specific embodiment, after the above S1022, the above S102 may further include:

[0080] S1023. Generate a particle special effect preview animation based on the three-dimensional model and the particle special effect parameters, and display the particle special effect preview animation in a preset window.

[0081] Specifically, after obtaining the above-mentioned particle special effect parameters, the above-mentioned electronic device can perform particle processing on the above-mentioned identified three-dimensional model based on the particle special effect parameters. For example, the nodes, edges, faces or volumes of the above-mentioned three-dimensional model can be converted into particles according to the particle special effect parameters to obtain a number of particles, and generate a particle special effect preview animation corresponding to the particle special effect parameters. Afterwards, the above-mentioned electronic device can also display the particle special effect preview animation in a preset window. For example, the complete particle special effect preview animation, or the first frame of the particle special effect preview animation can be displayed in the preset window, or any frame of the particle special effect preview animation selected by the user can be displayed in the preview window. In this way, the user can view and confirm the particle special effects corresponding to the particle special effect parameters in a timely manner, which greatly improves the visualization of the special effect production process.

[0082] And, in specific implementation, Figure 6As shown, the user can modify the value of the particle special effect parameter "Particles from" 64 on the special effect parameter setting interface to select which attribute (node, edge, surface or volume, etc.) of the three-dimensional model to generate particles. In this way, compared with the solution of generating a particle system based on a two-dimensional image in the prior art, a particle system with a three-dimensional form can be obtained, which is conducive to improving the realism of the object particle effect.

[0083] S1024. In response to the modification operation of the particle special effect parameters on the special effect parameter setting interface, determine the modified particle special effect parameters, and use the modified particle special effect parameters to update the particle special effect preview animation and the particle special effect parameters to be used in the three-dimensional model.

[0084] Specifically, when the user modifies the particle special effect parameters included in the above special effect parameter setting interface, the above electronic device can respond to the user's modification operation, re-acquire the particle special effect parameters included in the above special effect parameter setting interface to obtain the modified particle special effect parameters, and based on the modified particle special effect parameters, perform particle processing on the identified three-dimensional model to obtain a number of particles, and generate and display the particle special effect preview animation corresponding to the modified particle special effect parameters in the above preset window to update the screen displayed in the above preset window. In this way, the user can timely view and confirm the particle special effect corresponding to the modified particle special effect parameters, which is conducive to improving the visualization of the special effect production process.

[0085] In a specific embodiment, the above S1024 may specifically include:

[0086] S1-1. In response to a selection operation on an animation frame in a particle special effect preview animation, the particle special effect parameters corresponding to the selected animation frame are displayed on a special effect parameter setting interface.

[0087] Among them, the above-mentioned animation frame can be a custom frame in the above-mentioned special effects production software (for example, the first frame of the particle special effects preview animation), or it can be any frame of the particle special effects preview animation selected by the user in the above-mentioned special effects production software.

[0088] S1-2. In response to a modification operation on the particle special effects parameters corresponding to the selected animation frame, determine the modified particle special effects parameters corresponding to the selected animation frame, and use the modified particle special effects parameters corresponding to the selected animation frame to update the selected animation frame in the particle special effects preview animation and the particle special effects parameters to be used in the three-dimensional model.

[0089] Specifically, after the user sets or modifies the particle special effect parameters corresponding to the selected animation frame on the special effect parameter setting interface, the electronic device can obtain the particle special effect parameters corresponding to the selected animation frame set or modified by the user, and can calculate the particle special effect parameters of other frames in the particle special effect preview animation based on the particle special effect parameters corresponding to the selected animation frame according to preset rules or user-selected rules. In addition, after the electronic device generates and displays the corresponding particle special effect preview animation based on the particle special effect parameters of each frame, the user can modify the particle special effect parameters corresponding to a frame that he is not satisfied with or wants to modify in the particle special effect preview animation to achieve more delicate and realistic special effects.

[0090] It is understandable that the above special effect parameter setting interface and preset window can be displayed independently from the above special effect production interface, or can be displayed superimposed on the special effect production interface. In addition, in addition to the above particle special effect plug-in, the above electronic device can also be configured with other special effect plug-ins, and different special effect plug-ins can be used to produce different special effects.

[0091] S103. Determine a first material map of the three-dimensional model according to the first rendering map.

[0092] Among them, Figure 4 As shown, the above S103 may specifically include:

[0093] S1033. In response to the operation of specifying the first rendering image as the model material on the special effect parameter setting interface, the first rendering image is used as the first material image of the three-dimensional model.

[0094] Specifically, the user can directly identify the first rendering as the first material map of the three-dimensional model on the special effect parameter setting interface, so that the electronic device can respond to the user's identification operation of the first rendering as the model material on the special effect parameter setting interface and use the first rendering as the first material map of the three-dimensional model. The specific implementation of the identification operation of the first rendering as the model material can refer to the identification operation of the image as a layer map in the form particle plug-in, for example, Figure 7 As shown, when the user sets the value of the particle special effect parameter "Layer" 71 in the particle special effect parameter group "Layer Map (Master)" on the above-mentioned special effect parameter setting interface, the user can select the file of the above-mentioned first rendering image (for example, an image file with the file name "00000") to complete the identification operation of the first rendering image as the model material on the above-mentioned special effect parameter setting interface.

[0095] In some specific embodiments, before the above S1033, the following may also be included:

[0096] S1031. Display the first rendering in the preset window.

[0097] Specifically, after obtaining the above-mentioned model special effects material, the above-mentioned electronic device can generate different layers based on the three-dimensional model and the first rendering image in the model special effects material, and display the layer for displaying the three-dimensional model and the layer for displaying the first rendering image separately or in superposition in the above-mentioned preset window.

[0098] S1032. In response to the adaptation operation on the three-dimensional model and the first rendering, adapt the first rendering to the three-dimensional model.

[0099] The purpose of adapting the first rendering image to the three-dimensional model is to ensure the rendering effect when the particles are rendered based on the first rendering image in the subsequent steps. In addition, in specific implementation, the step of adapting the first rendering image to the three-dimensional model may specifically include: adjusting the angle at which the three-dimensional model is displayed in the preset window so that the angle is consistent with the first viewing angle; and / or adjusting the size of the first rendering image displayed in the preset window so that the edge of the first rendering image in the preset window coincides with the edge of the layer where the first rendering image is located.

[0100] In a specific embodiment, the electronic device can automatically adjust the camera angle in the special effects production software to adjust the display angle of the three-dimensional model in the preset window to the same rendering angle (i.e., the first viewing angle) corresponding to the first rendering. In some alternative embodiments, the electronic device can also adjust the display angle of the three-dimensional model in the preset window in response to the user's adjustment operation of the camera angle on the special effects production interface, or in response to the user's adjustment operation of the angle of the three-dimensional model displayed in the preset window, and the user can repeatedly adjust and view the angle until the user believes that the display angle of the three-dimensional model in the preset window is the same as the first viewing angle.

[0101] In a specific embodiment, the electronic device may adjust the edge of the first rendering in the preset window to overlap with the edge of the layer where the first rendering is located by automatically adjusting the size of the first rendering displayed in the preset window. In some alternative embodiments, the electronic device may also adjust the size of the first rendering displayed in the preset window in response to a user's resizing operation (e.g., zooming, edge stretching, etc.) on the first rendering displayed in the preset window, and the user may repeatedly adjust and view the size until the user believes that the edge of the first rendering in the preset window has overlapped with the edge of the layer where the first rendering is located.

[0102] Accordingly, the above S1033 may specifically include:

[0103] In response to an identification operation of using the first rendering image as a model material on the special effect parameter setting interface, the adapted first rendering image is used as a first material image of the three-dimensional model.

[0104] In some alternative embodiments, the above S1032 can also be executed after the above S1033, that is, the above electronic device can first use the first rendering as the first material map, and then adapt the identified first rendering to the above three-dimensional model in the above preset window, and the specific implementation method of adapting the identified first rendering to the above three-dimensional model can refer to the above-mentioned specific implementation method of adapting the first rendering to the three-dimensional model, so it will not be repeated here.

[0105] S104. Generate particle effects of the three-dimensional model according to the particle effects parameters and the first material map.

[0106] In this embodiment, the particle special effects can be motion animations of multiple or single particles, and can be used to simulate the convergence, dissipation, and other effects of objects. The particle special effects parameters are used to characterize the properties and motion modes of particles generated based on the three-dimensional model, and can include particle attribute parameters related to particle attributes such as particle size, particle shape, particle density, and particle lifespan, as well as particle motion parameters related to the particle motion mode such as motion force type, motion force magnitude, and force field range. The first material map is used to provide color information of each particle generated based on the three-dimensional model.

[0107] Among them, Figure 4 As shown, the above S104 may specifically include:

[0108] S1041. Particleize the three-dimensional model according to the particle attribute parameters to obtain a plurality of particles.

[0109] Specifically, the electronic device may perform particle processing on the identified three-dimensional model according to the particle attribute parameters, wherein: Figure 6 As shown, the above-mentioned particle attribute parameters may include the particle attribute parameter "particle comes from" 64, and when the value of the particle attribute parameter "particle comes from" 64 is "edge", the corresponding electronic device can convert the edge of the above-mentioned three-dimensional model into particles to obtain a plurality of particles.

[0110] In one embodiment, Figure 8 As shown, the three-dimensional model 80 may have a plurality of nodes P, edges L and faces M, and when the above particles are generated based on the edges L of the three-dimensional model 80, as shown in FIG. Fig. 9 As shown, corresponding to the above particles ( Fig. 9The basic form of the particles (shown as white particles in the figure) as a whole (that is, the form without any special effects added) can be the same as the form of all edges L in the three-dimensional model 80. By analogy, when the particles are generated based on the nodes P of the three-dimensional model 80, the basic form of the particles as a whole can be the same as the form of all nodes P in the three-dimensional model 80; when the particles are generated based on the surfaces M of the three-dimensional model 80, the basic form of the particles as a whole can be the same as the form of all surfaces M in the three-dimensional model 80; when the particles are generated based on the volume of the three-dimensional model 80, the basic form of the particles as a whole can be the same as the volume form of the three-dimensional model 80.

[0111] In this way, compared with the solution of generating a particle system based on a two-dimensional image in the prior art, a particle system with a three-dimensional form can be obtained, which is conducive to improving the realism of the particle effect of the object.

[0112] S1042. Render the particles according to the first material map to obtain rendered particles.

[0113] In this embodiment, after rendering the above-mentioned plurality of particles, a plurality of rendered particles can be obtained, and the display effect diagram of the plurality of rendered particles as a whole at the current viewing angle can be as follows: Fig.11 As shown, the display effect diagram can be combined with the electronic device according to the particle attribute parameters to the first material diagram (such as Fig.10 It is understandable that the purpose of adapting the first rendering image to the three-dimensional model is to make the current viewing angle equal to or approximately the first viewing angle corresponding to the first rendering image when rendering the particles, so that each particle can be rendered, and then the display effect image of the rendered particles at the current viewing angle can be similar to the first material image to the greatest extent, so as to ensure the particle rendering effect.

[0114] In specific implementation, the electronic device can read the color information of the layer where the first material map is located (for example, attributes such as RGB, Alpha or Lightness), and use the read color information (for example, the values ​​of attributes such as RGB, Alpha or Lightness) as the color information of the layer where the particles are located, so as to realize rendering of the particles.

[0115] S1043. Control the movement of the rendered particles according to the particle movement parameters to obtain particle special effects of the three-dimensional model.

[0116] Among them, Fig.12As shown, taking the particle special effect plug-in as the form particle plug-in as an example, the corresponding particle motion parameters may include "fluid force", "force life", "force relative position" and other particle special effect parameters that affect the flow effect of particles, among which, Fig.12 The particle special effect parameters contained in the special effect parameter setting interface correspond to a frame of particle motion after rendering. Fig.13 Furthermore, when making a dissipation effect of a three-dimensional model, the particle motion parameters may also include particle effect parameters related to the particle visibility of the key frame (such as Fig.14 shown).

[0117] In some embodiments, after completing the particle special effects of the above-mentioned three-dimensional model, the above-mentioned electronic device can also respond to user needs and use the particle special effects of the three-dimensional model as a basis in the above-mentioned special effects production software to add other special effects (for example, glowing special effects, shadow special effects, halo special effects or sharpening special effects, etc.) on the basis of the particle special effects of the three-dimensional model, so as to make the final displayed particle special effects more delicate and rich.

[0118] It is understandable that the particle special effects produced by the above S101 to S104 can be used as a model particle special effects template, and can be applied to other models that need to produce particle special effects. When applied to other models, it is only necessary to re-identify other models and a rendering of the model on the above special effect parameter setting interface. In this way, the model production cycle is greatly shortened and work efficiency is improved.

[0119] In the above embodiment, the above model special effect material may also include a second rendering of the three-dimensional model at a second viewing angle. Figure 4 As shown, after the above S104, it also includes:

[0120] S105. Determine a second material map of the three-dimensional model according to the second rendering map.

[0121] Among them, the specific implementation of the above S105 can refer to the specific implementation of determining the first material map of the three-dimensional model according to the first rendering map in the above S103. It is only necessary to replace the first rendering map with the second rendering map, and replace the first material map with the second material map in the description, so it will not be repeated here.

[0122] S106. Update the particle special effect using the second material and particle special effect parameters.

[0123] Specifically, the electronic device can generate a particle effect after modifying the material map according to the particle effect parameters and the second material map. Moreover, the specific implementation method of generating the particle effect after modifying the material map according to the particle effect parameters and the second material map can refer to the specific implementation method of generating the particle effect of the three-dimensional model according to the particle effect parameters and the first material map in S104 above, and it is only necessary to replace the first material map with the second material map in the description. In this way, after the particle effect of the three-dimensional model is completed, the color information of the particles in the particle effect can also be modified to facilitate the realization of different rendering effects.

[0124] From the above, it can be seen that the model special effects production method provided in this embodiment obtains model special effects materials, which include a three-dimensional model and a first rendering of the three-dimensional model at a first perspective, and then determines the particle special effects parameters to be used for the three-dimensional model, and determines the first material map of the three-dimensional model based on the first rendering map, and then generates the particle special effects of the three-dimensional model based on the particle special effects parameters and the first material map. Therefore, in the process of making model special effects, only one rendering of the model at the required perspective is required to complete the rendering of the model at one time, without the need for repeated rendering. This simplifies the production steps of the model special effects and saves rendering time while ensuring that the model special effects are delicate and realistic, thereby greatly shortening the production time of the model special effects.

Specifically, the above-mentioned first rendering image can be obtained by rendering the three-dimensional model produced by the above-mentioned material production software, and the corresponding first viewing angle can be the rendering angle of the three-dimensional model, and the selection of the rendering angle of the three-dimensional model can be achieved by adjusting the camera viewing angle or the camera angle in the above-mentioned material production software.
