[0052] The principles and spirit of this application will be elaborated in detail below with reference to several representative embodiments of this application. Summary of the Invention

[0054] In the prior art, generally, a particle emitter or a ribbon model emitter is bound and hung on the skeleton of the model to simulate the fluid residue trace or sliding trace during the movement of the character. When the action amplitude of the model in the model animation is large or the displacement speed is fast, the particles or ribbons attached to the model animation will break, and it is impossible to show the smoke fluid effect similar to that generated by natural settlement. At the same time, in terms of consumption, due to the size limitation of the particles, in order to make the particles have viscosity, a large number of particle simulations are required, which will cause the performance of the playback engine to decline, and there are significant differences in the contour and implementation method of the model ribbon and the texture of the fluid smoke.

[0056] Obtain the loop animation of the dynamic model to be processed; determine the frames in the loop animation where the amplitude of the dynamic model is greater than the amplitude threshold as key frames, and extract the target dynamic model from the key frames; generate the special effect animation of the target dynamic model based on the loop animation; apply the special effect animation to the playback process of the dynamic model, so that the dynamic model generates the model animation special effect during playback, thereby realizing directly adding the special effect animation to the target dynamic model, avoiding the breakage of the special effect when the action amplitude of the dynamic model is large or the displacement speed is fast, and avoiding using a large number of particles to participate in the simulation, thereby improving the operating performance of the playback hardware.

[0057] After introducing the basic principles of this application, the various non-limiting embodiments of this application will be specifically introduced below.

[0058] Overview of Application Scenarios

[0059] In some specific application scenarios, the method for generating model animation special effects of this application can be applied to model production and systems related to model production, such as Unity, 3dmax, etc.

[0060] In some specific application scenarios, the method for generating model animation special effects of the present application can be directly run locally or on a cloud server. When running on a cloud server, the obtained data to be processed is sent to the cloud server through the network. The server processes the data to be processed by the method for generating model animation special effects of the present application, and sends the processing result to the local through the network.

[0061] The following describes the method for generating model animation special effects according to an exemplary embodiment of the present application in combination with specific application scenarios. It should be noted that the above application scenarios are only shown for the convenience of understanding the spirit and principle of the present application, and the embodiments of the present application are not limited in this regard. On the contrary, the embodiments of the present application can be applied to any applicable scenario.

[0062] Exemplary Method

[0063] Refer to Figure 1 , the embodiment of the present application provides a method for generating model animation special effects, including the following steps:

[0064] S101, obtain the loop animation of the dynamic model to be processed.

[0065] In specific implementation, a dynamic model generally has a loop animation. For example, if a dynamic model is a pair of waving wings, then the loop animation of the wings is the animation of the wings waving repeatedly. When adding special effects to the model animation, first obtain the loop animation of the dynamic model to be processed.

[0066] S102, determine the frames in the loop animation where the spread of the dynamic model is greater than the spread threshold as key frames, and extract the target dynamic model from the key frames.

[0067] In specific implementation, first determine the key frames in the loop animation of the dynamic model where the spread of the dynamic model is greater than the spread threshold. The spread threshold can be set as needed and is not limited here. Optionally, the spread threshold can be as close as possible to the maximum spread of the dynamic model, so that the determined key frames with a spread greater than the spread threshold can include all details of the dynamic model and cover the dynamic models corresponding to other spreads. After determining the key frames in the loop animation where the spread of the dynamic model is greater than the spread threshold, extract the target dynamic model to which the animation special effects will be added from these key frames. Refer to Figure 2 , which is a schematic diagram of the key frames in the loop animation of the dynamic model where the spread of the dynamic model is greater than the spread threshold in the embodiment of the present application. Among them, 100 is the target dynamic model. Optionally, other parts can be eliminated through the collapse function of the model production system, and then the target dynamic model can be extracted. Refer to Figure 3 , which is a schematic structural diagram of a target dynamic model in the embodiment of the present application. Among them, Figure 3The target dynamic model 100 in Figure 2 is the extracted target dynamic model 100.

[0068] S103. Generate a special effect animation of the target dynamic model based on the loop animation.

[0069] In specific implementation, after the target dynamic model is extracted, a special effect animation of the target dynamic model is generated according to the original loop animation of the dynamic model. This special effect animation is an animation including special effect features and can display the fluid special effects during the movement of the model. The fluid can be liquid or smoke.

[0070] In some embodiments, generating a special effect animation of the target dynamic model based on the loop animation specifically includes:

[0071] Add special effect features to the target dynamic model to obtain a target special effect model;

[0072] Add an animation to the target dynamic model based on the loop animation to obtain a trajectory animation of the target dynamic model;

[0073] Obtain the special effect animation of the target dynamic model based on the target special effect model and the trajectory animation.

[0074] In specific implementation, after the target dynamic model is extracted, special effect features can be added to the target dynamic model first to obtain a target special effect model, and then an animation is added to the target special effect model with added special effect features according to the loop animation of the dynamic model, so that the target special effect model with added special effect features has a special effect animation consistent with the loop animation of the dynamic model. In some embodiments, an animation can also be added to the target dynamic model according to the loop animation first to obtain a trajectory animation of the target dynamic model, and then special effect features are added to the target dynamic model with added animation, so as to obtain the special effect animation of the target dynamic model. It should be noted that in this embodiment, the process of obtaining the special effect animation of the target dynamic model includes two steps: adding special effect features and adding an animation. The order of these two steps is not limited here, and those skilled in the art can choose arbitrarily according to needs.

[0075] In some embodiments, adding an animation to the target dynamic model based on the loop animation specifically includes:

[0076] Add a preliminary animation corresponding to the loop animation to the target dynamic model;

[0077] Determine the start playing time and playing duration of the preliminary animation based on the start playing time and playing duration of the loop animation.

[0078] In specific implementation, an animation can be directly added to the target dynamic model according to the loop animation, and the animation added to the target dynamic model is used as the trajectory animation of the target dynamic model. Optionally, a preliminary animation consistent with the loop animation can be added to the target dynamic model through dynamic calculation, and then the start playback time and playback duration of the preliminary animation are set to the start playback time and playback duration of the loop animation. Of course, those skilled in the art can also add an animation consistent with the loop animation to the target dynamic model through other existing technical means, which is not limited herein.

[0079] It should be noted that since the preliminary animation added to the target dynamic model is a newly generated animation, in some embodiments, in order to display some ghosting or other special animation effects, the start playback time of the preliminary animation can be reset as needed to be different from the start playback time of the loop animation.

[0080] Since the original loop animation of the dynamic model is generally driven by the bone points on the dynamic model, but the animation directly added to the target dynamic model does not control the movement of the entire model through the bone points on the dynamic model, this results in poor compatibility between the added animation and the original loop animation of the dynamic model, and is prone to causing system jitter. To avoid this drawback, in some embodiments, an animation is added to the target dynamic model based on the loop animation to obtain the trajectory animation of the target dynamic model, specifically including:

[0081] Determine a plurality of bone points from the target dynamic model after adding the animation, and save the first movement trajectory of each bone point in the trajectory animation;

[0082] Delete the trajectory animation of the target dynamic model, and determine the second movement trajectory of each point in the target dynamic model in the trajectory animation based on all the first movement trajectories;

[0083] Obtain the trajectory animation of the target dynamic model based on the second movement trajectory of each point in the target dynamic model in the trajectory animation.

[0084] In a specific embodiment, after adding an animation corresponding to the loop animation to the target dynamic model, a plurality of bone points are first determined from the target dynamic model after adding the animation. These bone points are some important points on the target model. Optionally, these bone points can be determined randomly. Since each point in the target dynamic model after adding the animation already has a trajectory animation, that is, the movement trajectory of each point in the trajectory animation is determined. After determining the bone points, the first movement trajectory of each bone point in the trajectory animation can be saved, and then the determined bone points can be separated from the trajectory animation of the target dynamic model to save their respective first movement trajectories separately. After saving the first movement trajectory, the trajectory animation of the target dynamic model can be deleted, and then the second movement trajectory of each point in the target dynamic model in the trajectory animation can be determined according to the first movement trajectories of all the bone points. Finally, the trajectory animation of the target dynamic model can be obtained according to the second movement trajectories of each point in the target dynamic model in the trajectory animation.

[0085] In some embodiments, determining the second movement trajectory of each point in the target dynamic model in the special effect animation based on all the first movement trajectories specifically includes:

[0086] Determine the target point in the target dynamic model;

[0087] Determine the influence weight of each bone point on the target point based on the distance between the target point and each bone point;

[0088] Determine the second movement trajectory of the target point in the special effect animation based on all the first movement trajectories and the influence weight of each bone point on the target point.

[0089] During specific implementation, a target point is first determined from all the points in the target dynamic model. Optionally, this target point can be each point in the dynamic model. After determining the target point, the influence weight of each bone point on the target point can be determined according to the distance between the target point and each bone point. Generally, the greater the distance between the target point and the bone point, the greater the influence weight of this bone point on the target point. Optionally, when the distance between the target point and a certain bone point is 0, the influence weight of this bone point on the target point is the largest. Optionally, this maximum influence weight can be set to 1, and the influence weights of other bone points on the target point are set to 0, that is, when the target point coincides with a certain bone point, the second movement trajectory of this target point is the first movement trajectory of the corresponding bone point. Optionally, in order to further accurately control the movement trajectory of the target point, when the distance between the movement trajectory of the target point and a certain bone point is greater than a preset threshold, the influence weight of this bone point on the target point is set to 0.

[0090] In some embodiments, the second motion trajectory of the target point in the special effect animation is determined by the following formula:

[0091] A = A1 * P1 + A2 * P2 + A3 * P3 + … + An * Pn;

[0092] Wherein, A represents the second motion trajectory of the target point in the special effect animation, A1, A2, A3 … An respectively represent the first motion trajectories of each bone point, P1, P2, P3 … Pn respectively represent the influence weights of each bone point on the target point, and n is a positive integer. It should be noted that the specific quantity of n is not limited herein, and those skilled in the art can set it as needed.

[0093] In some embodiments, determining multiple bone points from the target dynamic model after adding the animation specifically includes:

[0094] Determining the positions and quantities of the multiple bone points based on the shape of the target dynamic model.

[0095] Specifically in implementation, the positions and quantities of the bone points determined by the target dynamic model are mainly related to the shape of the target dynamic model. Generally, the more complex the shape of the target dynamic model, the more bone points are required. In order to effectively control various-shaped target dynamic models to make different animation actions through a limited number of bone points, for target dynamic models of different shapes, the positions of the bone points to be determined are all different. Optionally, the positions of the bone points on target dynamic models of multiple shapes can be determined in advance through experiments and a position comparison table can be generated. When determining the positions of the bone points on the target dynamic model, first obtain the shape of the target dynamic model, and then determine the positions of each bone point from the position comparison table according to the shape of the target dynamic model.

[0096] S104, applying the special effect animation to the playback process of the dynamic model so that the dynamic model generates the model animation special effect during playback.

[0097] Specifically in implementation, after obtaining the special effect animation of the target dynamic model, apply the special effect animation to the playback process of the dynamic model so that the dynamic model generates the model animation special effect during playback.

[0098] In some embodiments, applying the special effect animation to the playback process of the dynamic model specifically includes:

[0099] Obtaining the playback engine of the dynamic model:

[0100] Adding the special effect animation to the playback engine.

[0101] It should be noted that the playback engine is used to play and store the dynamic model. Optionally, the playback engine can be Unity, 3dmax, NeoX, etc.

[0102] In some embodiments, during the process of applying the special effect animation to the playback of the dynamic model, before the dynamic model generates the model animation special effect during playback, the method further includes:

[0103] Adjusting the color parameters of the target dynamic model in the special effect animation.

[0104] In specific implementation, by adjusting the color parameters of the target dynamic model in the special effect animation, some additional visual effects can be added to the generated model animation special effect. For example, by changing the transparency of the color of the target dynamic model, the finally obtained model animation special effect can be made more hazy.

[0105] The method for generating the model animation special effect provided by this application includes: obtaining the loop animation of the dynamic model to be processed; determining the frames in the loop animation where the spread of the dynamic model is greater than the spread threshold as key frames, and extracting the target dynamic model from the key frames; generating the special effect animation of the target dynamic model based on the loop animation; applying the special effect animation to the playback process of the dynamic model, so that the dynamic model generates the model animation special effect during playback, thereby directly adding the special effect animation to the target dynamic model, avoiding the breakage of the special effect when the dynamic model has a large action amplitude or a fast displacement speed, and avoiding using a large number of particles to participate in the simulation, thereby improving the running performance of the playback hardware.
