[0077] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0078] Embodiments of the present invention provide an animation generation method, device, terminal and storage medium.

[0079] The animation generating device can be integrated into an electronic device, which can be a terminal, a server, etc. The terminal can be a mobile phone, a tablet computer, a smart Bluetooth device, a laptop, or a personal computer (PC), etc. The server can be a single server or a server cluster composed of multiple servers.

[0080] In some embodiments, the animation generating device may also be integrated into multiple electronic devices. For example, the animation generating device may be integrated into multiple servers, and the animation generating method of the present invention may be implemented by multiple servers.

[0081] In some embodiments, the server may also be implemented in the form of a terminal.

[0082] For example, refer to Figure 1a The electronic device can obtain the character skeleton of the game character model and the character animation corresponding to the character skeleton, wherein the character skeleton includes a connecting sub-skeleton, and the connecting sub-skeleton corresponds to the connecting sub-skeleton animation in the character animation; construct an object skeleton chain of the game object model on the character skeleton of the game character model, wherein the object skeleton chain includes a chain head segment located at the front end of the object skeleton chain, and the chain head segment is mounted on the connecting sub-skeleton; based on the connecting sub-skeleton animation, construct a chain head segment animation corresponding to the chain head segment; based on the chain head segment animation, generate an object animation corresponding to the object skeleton chain; while the game character model executes the character animation, the game object model executes the object animation.

[0083] It should be noted that the serial numbers of the following embodiments are not intended to limit the preferred order of the embodiments.

[0084] In this embodiment, an animation generation method is provided, such as Figure 1b As shown, the specific process of the animation generation method can be as follows:

[0085] 101. Obtain a character skeleton of a game character model and a character animation corresponding to the character skeleton. The character skeleton includes a link sub-bone, and the link sub-bone corresponds to the link sub-bone animation in the character animation.

[0086] There are many ways to obtain the character skeleton of the game character model and the character animation corresponding to the character skeleton.

[0087] For example, the character skeleton of the game character model and the character animation corresponding to the character skeleton can be obtained by reading the character skeleton of the game character model stored in the local memory; for another example, the character skeleton of the game character model and the character animation corresponding to the character skeleton can be obtained by communicating with the animation database through the network; for another example, the character skeleton of the game character model and the character animation corresponding to the character skeleton can be manually made by an animator in the animation production software, and so on.

[0088] Among them, the character skeleton, namely the Bip skeleton, can be used to execute the physical motion information of the game character model, and the physical motion information is the character animation corresponding to the character skeleton.

[0089] The game role model may be a game character model, a game animal model, and so on.

[0090] 102. Construct an object skeleton chain of a game object model on the character skeleton of the game character model, wherein the object skeleton chain includes a chain head segment located at the front end of the object skeleton chain, and the chain head segment is mounted on a connecting sub-bone.

[0091] Corresponding to the character skeleton is the object skeleton chain, namely the Bone skeleton. The object skeleton chain is the skeleton of the game object model mounted on the character skeleton, among which the link sub-bone in the Bip skeleton is connected to the chain head segment in the Bone skeleton.

[0092] Among them, the game object model can be equipment, an object model mounted on a game character model, for example, the game object model can be a floating accessory, such as a skirt, long hair, sleeves, ribbons, etc.

[0093] For example, refer to Figure 1c , the gray part of the figure is the character skeleton, and the white part is the object skeleton chain. Figure 1c In the figure, 7 object bone chains are mounted on the character skeleton, and the first segment of each object bone chain can be connected to the connecting child bone on the character skeleton.

[0094] Each object bone chain can be connected to different linked child bones on the character skeleton.

[0095] In this solution, each sub-bone in the character skeleton (including connecting sub-bones) can have its corresponding sub-bone animation, that is, the connecting sub-bone can have its corresponding connecting sub-bone animation, and all sub-bone animations constitute the character animation of the character skeleton.

[0096] For example, Figure 1c The character animation of the character skeleton shown is head turning. In this head turning animation, only the head sub-bone in the character skeleton rotates, and other sub-bones do not need to perform physical movements.

[0097] There are many ways to construct the object skeleton chain of the game object model on the character skeleton of the game character model.

[0098] For example, an animator may manually construct an object skeleton chain of a game object model on the character skeleton of a game character model; for another example, the object skeleton chain of a game object model may be automatically obtained and mounted on the character skeleton of a game character model, and so on.

[0099] In some embodiments, in order to improve the realistic physical performance of the game object model when performing physical motion, especially when the game object model is a soft streamer, the object skeleton chain may be composed of multiple segments, and step 102 may include the following steps:

[0100] (1) Mount the chain head segment on the link sub-bone of the game character model;

[0101] (2) Mounting the middle segment on the chain head segment;

[0102] (3) Mounting the tail segment on the middle segment;

[0103] The object skeleton chain may include a tail segment located at the last end of the object skeleton chain and an intermediate segment located between the head segment and the tail segment.

[0104] For example, refer to Figure 1c , Figure 1c Each object skeleton chain in has a chain head segment, two middle segments and a chain tail segment.

[0105] It should be noted that, in some embodiments, the object skeleton chain may have only one chain head segment and one chain tail segment, without any intermediate segment; in some embodiments, the object skeleton chain may have only one chain head segment, without any intermediate segment or chain tail segment; in some embodiments, the object skeleton chain may have one chain head segment, N intermediate segments and one chain tail segment, where N is a positive integer.

[0106] In some embodiments, in order to facilitate operation and overview of all object skeleton chains, a skeleton chain page is provided, so the following steps may be included after step 102:

[0107] Display the bone chain page;

[0108] The bone chain page displays the identifiers corresponding to the connected sub-bones, the identifier corresponding to the first segment of the chain, the identifier of the middle segment and the identifier of the last segment of the chain. The identifier corresponding to the first segment of the chain is connected to the identifier corresponding to the connected sub-bones, the identifier corresponding to the first segment of the chain is connected to the identifier of the middle segment, and the identifier of the middle segment is connected to the identifier of the last segment of the chain.

[0109] Among them, the logo can be expressed in the form of text, numbers, symbols, etc.

[0110] The label can be a name. The bone chain page can display the name of the connected child bone and all the object bone chains mounted on the connected child bone. Each object bone chain is represented by the name of the chain head segment, the name of the middle segment and the name of the chain tail segment.

[0111] For example, refer to Figure 1d , the bone chain page can display the connected child bone Bip_001 and the 7 object bone chains mounted on Bip_001. Taking the sixth object bone chain as an example, the sixth object bone chain includes the chain head segment [Bone_6_1], the middle segment [Bone_6_2], the middle segment [Bone_6_3] and the chain tail segment [Bone_6_4].

[0112] In some embodiments, when it is detected that the user has selected any mark in the skeleton chain page, the animation of the segment corresponding to the mark can be displayed to the user, and the animation can include x frames of animation pictures, where x is any positive integer.

[0113] For example, reference Figure 1d When the user clicks [Bone_6_2], the x-frame animation of the second positive segment in the sixth object's bone chain will be displayed.

[0114] For example, to display x frames of animation for each segment, you can use Figure 1e The frame track shown is displayed, which uses time as the horizontal axis (that is, its scale is frames) and contains tracks of multiple frame identifiers.

[0115] The frame identifier is used to represent a frame of animation. Figure 1e In the example, the frame mark is a white strip, which represents a frame of animation. When it is detected that the user clicks on a white strip in the frame track, the frame of animation corresponding to the white strip can be displayed on the page.

[0116] 103. Based on the link sub-bone animation, construct the chain head segment animation corresponding to the chain head segment.

[0117] In steps 101-102, a character skeleton is established, and a plurality of object skeleton chains are added to the character skeleton. In some embodiments, since the animator needs to animate the object skeleton chains in addition to the character skeleton, the animator also needs to animate the object skeleton chains.

[0118] In order to reduce the time consumed by animators in making object animations corresponding to all object skeleton chains frame by frame and in accordance with the real-time physical laws, thereby improving the efficiency of animation generation, this embodiment proposes a method in which a user only needs to make a chain head segment animation corresponding to the chain head segment in any object skeleton chain, and based on the chain head segment animation, the object animations corresponding to all object skeleton chains can be generated in step 104.

[0119] The animation may include multiple frames of animation pictures, therefore, the link sub-bone animation may include multiple frames of link sub-bone animation pictures, and the chain head segment animation may include multiple frames of chain head segment animation pictures.

[0120] Through step 103, the problems of complicated operation and time-consuming caused by manually constructing the chain head segment animation corresponding to the chain head segment of each object skeleton chain one by one based on the linked sub-skeleton animation can be effectively solved, thereby greatly improving the animation generation efficiency.

[0121] In addition, first frame inconsistency refers to the problem that the appearance time of the first frame in two animations is inconsistent, and / or the appearance time of the last frame is inconsistent. For example, if the first frame of the character animation and the ribbon animation are inconsistent, the physical movement of the character and the ribbon in the animation will be out of sync, resulting in a strong sense of incongruity.

[0122] In some embodiments, in order to solve the problem that the first frame between the link sub-skeletal animation and the chain head segment animation corresponding to each chain head segment is inconsistent, step 103 may include the following steps:

[0123] (1) Display frame alignment controls in the interface;

[0124] (2) When a trigger operation for the frame alignment control is detected, the generation time of each frame of the linked sub-skeleton animation picture is determined;

[0125] (3) Generate a blank frame of the chain head segment according to the generation time of each frame of the linked sub-skeleton animation picture;

[0126] (4) Based on the animation creation operation for a blank frame, a frame of chain head segment animation corresponding to the chain head segment is obtained.

[0127] The frame alignment control may be presented in the form of a button, a check box, etc.

[0128] The blank frame refers to a blank frame, that is, a preset blank frame is generated, but the preset blank frame does not contain any model object.

[0129] The animator can create animation for the blank frame by placing a game model in the blank frame, designing actions for the game model, etc., and finally obtain a frame of animation for which the animation is created, that is, a frame of chain head segment animation corresponding to the chain head segment.

[0130] The generation time of the animation picture refers to the time in which second the animation picture is displayed;

[0131] In the present application, a blank frame of the chain head segment can be generated according to the generation time of each frame of the connected sub-skeleton animation picture; and then based on the animation creation operation for the blank frame, a chain head segment animation frame corresponding to the chain head segment is obtained.

[0132] That is to say, the generation time of the animation picture of the link sub-bone corresponds to the generation time of the animation picture of the chain head segment.

[0133] For example, if the generation time of the animation picture of the i-th frame connected to the sub-skeleton is 00:12:01, then the generation time of the animation picture of the i-th frame chain head segment is also 00:12:01, where i is a positive integer.

[0134] In some embodiments, the step "(3) generating a blank frame of the chain head segment according to the generation time of each frame of the linked sub-skeleton animation frame" may also include the following steps:

[0135] Display the frame track on the page. The frame track is a track with time as the horizontal axis and contains frame labels;

[0136] According to the generation time, a frame identifier corresponding to the blank frame image is generated in the frame track.

[0137] For example, refer to Figure 1e , Figure 1e A frame track is displayed, which includes multiple frames. Assuming that the duration of each frame is 0.1 seconds, the generation time of the 0th frame of animation is 0, the generation time of the 1st frame of animation is 00:00:00.1 seconds, the generation time of the 2nd frame of animation is 00:00:00.2 seconds, the generation time of the 3rd frame of animation is 00:00:00.3 seconds…, and the generation time of the 100th frame of animation is 00:00:10 seconds.

[0138] 104. Based on the chain head segment animation, generate the object animation corresponding to the object skeleton chain.

[0139] Among them, the object animation can include the chain head segment animation, the middle segment animation and the chain tail segment animation, and the animation can include multiple frames of animation pictures. Therefore, the object animation can include multiple frames of chain head segment animation pictures, multiple frames of middle segment animation pictures, and multiple frames of chain tail segment animation pictures.

[0140] In the embodiment of the present application, the object animation corresponding to all object skeleton chains can be automatically generated based on only the chain head segment animation of any object skeleton chain, thereby reducing the user's operation complexity and improving the animation generation efficiency. Therefore, in some embodiments, step 104 may include the following steps:

[0141] (1) determining the physical motion parameters of the chain head segment in the previous frame of the chain head segment animation picture;

[0142] (2) Based on the physical motion parameters of the chain head segment, the middle segment animation of the middle segment and the chain tail segment animation of the chain tail segment are generated.

[0143] The previous frame refers to the animation frame before the current frame, and the next frame refers to the animation frame after the current frame. Figure 1e , assuming the current frame is the 7th frame, the previous frame is the 6th frame, and the next frame is the 8th frame.

[0144] In this embodiment, whenever the physical motion parameters of the middle segment and the physical motion parameters of the chain tail segment are to be determined, they can be determined based on the physical motion parameters of the chain head segment in the previous frame of the chain head segment animation picture.

[0145] For example, in some embodiments, whenever the physical motion parameters of the middle segment in the middle segment animation picture of the current frame and the physical motion parameters of the end segment in the end segment animation picture of the current frame need to be determined, they can be determined based on the physical motion parameters of the head segment in the head segment animation picture of the previous frame.

[0146] Among them, according to Ph i-1 Ask for Ph i , and according to Ph i Then determine Pm i and Pt i There are many ways to calculate Ph. i 、Pm i , Pt i The visual effects reflected on the object skeleton chain are also different, which will not be expanded here. Among them, the current frame is the i-th frame, Ph i-1 Refers to the physical motion parameter of the first segment h of the i-1th frame, Ph i Refers to the physical motion parameters of the first segment h of the i-th frame chain, Pm iRefers to the physical motion parameter of the middle segment m of the i-th frame, Pt i Refers to the physical motion parameters of the tail segment t of the i-th frame.

[0147] In some embodiments, the physical motion parameters may include the softness of the skeletal chain, and the step “(2) generating the middle segment animation of the middle segment and the chain tail segment animation of the chain tail segment based on the physical motion parameters of the chain head segment” may include the following steps:

[0148] Display softness controls in the page;

[0149] When a softness modification operation for a softness control is detected, the softness of the bone chain corresponding to the softness modification operation is obtained;

[0150] Based on the physical motion parameters of the chain head segment and the softness of the bone chain, the middle segment animation of the middle segment and the chain tail segment animation of the chain tail segment are generated.

[0151] The softness control may be presented in the form of a button, a check box, an input box, a drag bar, etc.

[0152] When the user modifies the softness of the object's bone chain through the softness control, the above Ph i 、Pm i , Pt i The weighted processing is performed so that the final intermediate segment animation and the chain tail segment animation can be controlled by the user to show the degree of softness or hardness.

[0153] In some embodiments, the step “(2) generating the middle segment animation of the middle segment and the tail segment animation of the tail segment based on the physical motion parameters of the head segment” may include the following steps:

[0154] Based on the physical motion parameters of the chain head segment, the middle segment animation of the middle segment is generated;

[0155] Determine the physical motion parameters of the middle segment in the previous frame of the middle segment animation;

[0156] The chain tail segment animation of the chain tail segment is generated based on the physical motion parameters of the middle segment in the middle segment animation of the previous frame.

[0157] For example, the current frame is the i-th frame, when the physical motion parameter Ph of the chain head segment h in the i-1-th frame chain head segment animation picture is known i-1 When , the physical motion parameter Pm of the middle segment m in the middle segment animation picture of the i-th frame can be obtained i , and the physical motion parameter Pt of the chain tail segment t in the i-th frame chain tail segment animation picture i .

[0158] Specifically, in some embodiments, whenever the physical motion parameters of the middle segment in the middle segment animation picture of the current frame and the physical motion parameters of the tail segment in the tail segment animation picture of the current frame need to be determined, they can be determined based on the physical motion parameters of the first segment in the first segment animation picture of the current frame; and the physical motion parameters of the first segment in the first segment animation picture of the current frame can be determined by the physical motion parameters of the first segment in the first segment animation picture of the previous frame.

[0159] For example, the current frame is the i-th frame, when the physical motion parameter Ph of the chain head segment h in the i-1-th frame chain head segment animation picture is known i-1 When , the physical motion parameter Ph of the chain head segment in the i-th frame chain head segment animation picture can be obtained i , according to Ph i Then Pm can be determined i and Pt i .

[0160] 105. While the game character model executes character animation, the game object model executes object animation.

[0161] Skin is a 3D animation production technology. The technology of binding a model to a skeleton is called Bind Skin. Since the skeleton and the model are independent of each other, in order for the skeleton to drive the model to produce reasonable movement, the outer contour of the model controlled by the skeleton needs to be bound to the skeleton.

[0162] In some embodiments, before step 105, the model may be skinned based on the skeleton. Therefore, before step 105, the following steps may be included:

[0163] Based on the character skeleton of the game character model, the game character model is subjected to skinning and binding processing to obtain a bound game character model;

[0164] Based on the object skeleton chain of the game object model, the game object model is subjected to skinning and binding processing to obtain the bound game object model;

[0165] Therefore, step 105 may include the following steps:

[0166] While the bound game character model executes character animation, the bound game object model executes object animation.

[0167] Since each time the skeleton animation is automatically generated, there are often frames with calculation errors (i.e., waste frames), and the positions of these waste frames are often far away before or after the animation starts or ends (even thousands or tens of thousands of frames). In order to reduce the time required for detecting and removing waste frames and improve the removal efficiency, in some embodiments, in order to remove waste frames in the generated animation and improve the accuracy of each current animation frame, the following steps can also be performed after step 104 and before step 105:

[0168] (1) When a frame cleaning trigger operation is detected, a waste frame filtering operation is performed on the object animation to obtain multiple waste frames in the object animation;

[0169] (2) Eliminate the waste frames from the object animation to obtain a cleaned frame animation.

[0170] In some embodiments, after step "(2) removing waste frames from the object animation to obtain a cleaned frame animation", information corresponding to the waste frames can also be displayed on the page to provide information support for users, so that users can understand the removed waste frames.

[0171] Therefore, in step 105, the game character model can execute the post-clearing frame animation while the game object model executes the character animation.

[0172] There are many ways to perform the waste frame filtering operation. For example, in some embodiments, the step “(1) performing the waste frame filtering operation on the object animation to obtain a plurality of waste frames in the object animation” may include the following steps:

[0173] A. Get the preset reference range of waste frames;

[0174] B. When an animation picture in the object animation meets the waste frame reference range, the animation picture is determined as a waste frame in the object animation.

[0175] For example, the preset waste frame reference range refers to the position range where waste frames appear before or after the animation starts or ends. For example, assuming that the preset waste frame reference range is (-∞, 0) and (800, +∞), when a frame of animation meets the preset waste frame reference range, that is, the frame of animation appears before the 0th frame or after the 800th frame, the frame of animation is determined as a waste frame in the object animation.

[0176] It should be noted that, in some embodiments, in addition to judging the position of a waste frame, the criterion for judging whether a waste frame is a waste frame may also be determined by detecting whether the frame is rotated or scaled incorrectly.

[0177] For example, in some embodiments, the preset waste frame reference range may include a position reference range, a rotation reference range, and a scaling reference range, and the step “B. when the animation picture in the object animation meets the waste frame reference range, determining the animation picture as a waste frame in the object animation” may include the following steps:

[0178] b1. When the animation screen in the object animation meets the position reference range, the animation screen is determined as a waste frame in the object animation;

[0179] b2. When the animation screen in the object animation meets the rotation reference range, the animation screen is determined as a waste frame in the object animation;

[0180] b3. When the animation picture in the object animation meets the scaling reference range, the animation picture is determined as a waste frame in the object animation.

[0181] For example, the preset position reference range is (-∞, 0) and (800, +∞). When a frame of animation meets the position reference range, that is, the frame of animation appears before the 0th frame or after the 800th frame, the frame of animation is determined as a waste frame in the object animation.

[0182] For example, the preset rotation reference range is (-∞, 30) and (30, +∞). When a frame of animation meets the rotation reference range, that is, the frame of animation is rotated counterclockwise by more than 30°, or rotated clockwise by more than 30°, the frame of animation is determined as a waste frame in the object animation.

[0183] For example, the preset scaling reference range is (0, 0.8) and (1.2, +∞), and the original size of the animation picture is Q. Then, when a frame of the animation picture meets the scaling reference range, that is, the size of the frame of the animation picture is less than 0.8Q, or the size of the frame of the animation picture is greater than 1.2Q, then the frame of the animation picture is determined as a waste frame in the object animation.

[0184] As can be seen from the above, the embodiment of the present invention can obtain the character skeleton of the game character model, and the character animation corresponding to the character skeleton. The character skeleton may include a connecting sub-skeleton, and the connecting sub-skeleton corresponds to the connecting sub-skeleton animation in the character animation; construct an object skeleton chain of the game object model on the character skeleton of the game character model, and the object skeleton chain may include a chain head segment located at the front end of the object skeleton chain, and the chain head segment is mounted on the connecting sub-skeleton; based on the connecting sub-skeleton animation, construct a chain head segment animation corresponding to the chain head segment; based on the chain head segment animation, generate an object animation corresponding to the object skeleton chain; while the game character model executes the character animation, the game object model executes the object animation.

[0185] In the embodiment of the present invention, the user does not need to debug the corresponding object animations for all the object skeleton chains mounted on the character skeleton one by one. The user only needs to build the chain head segment animation for the chain head segment of any object skeleton chain. The solution can automatically generate the object animations corresponding to all the object skeleton chains. The object animation generation efficiency is high, and the generated object animation effect is realistic and accurate. Therefore, the embodiment of the present invention can automatically build the object animation of the game object model through the connection sub-skeleton animation of the game character model, thereby improving the efficiency of animation production.

[0186] The method described in the above embodiment will be further described in detail below.

[0187] In the process of game development, developers need to create a lot of character animations. In addition, if the game character has a lot of floating accessories, such as skirts, long hair, sleeves, ribbons and even props ribbons, the object animations of these floating objects are often made manually frame by frame.

[0188] Especially when there are a large number of game characters and floating objects, the animation generation solution provided by the embodiment of the present invention can be applied in various game development scenarios to improve the generation efficiency and accuracy of object animation.

[0189] For example, in this embodiment, the method of the embodiment of the present invention will be described in detail by taking the generation of the hem animation of a coat equipped on a game character as an example.

[0190] like Figure 2a As shown, the specific process of an animation generation method is as follows:

[0191] 201. Set up a character skeleton of a game character, and N hem skeleton chains mounted on the character skeleton, wherein the hem skeleton chain includes a chain head segment, a middle segment, and a chain tail segment.

[0192] In this embodiment, the skeleton chain refers to the hem skeleton chain, namely, the Bone skeleton; and the character skeleton is the Bip skeleton.

[0193] In the following text, the bone chain is referred to as the hem bone chain.

[0194] 202. Skin and bind the skeleton of the game character and N clothing hem skeleton chains.

[0195] 203. Create character animation for the skinned character skeleton, and generate blank frames according to the time parameters of each frame in the character animation.

[0196] 204. Based on the blank frame, create a chain head segment animation for the chain head segment of the target bone chain after skinning, and the target bone chain is any hem bone chain.

[0197] Generating the chain head segment animation based on the blank frame can solve the problem of inconsistent first frame.

[0198] In this embodiment, only one chain head segment animation needs to be produced for the chain head segment of any target bone chain after skinning. Steps 205 to 206 can automatically generate the hem animation of all hem bone chains based on the chain head segment animation, without the need for the user to manually repeat work, thereby improving the efficiency of animation generation.

[0199] 205. Generate chain head segment animations of other bone chains according to the chain head segment animation of the target bone chain. The other bone chains are other hem bone chains among the N hem bone chains except the target bone chain.

[0200] 206. Generate the chain tail segment animation of the chain tail segment and the middle segment animation of the middle segment in the hem skeleton chain according to the chain head segment animation of the hem skeleton chain.

[0201] 207. Clean up the waste frames of the hem animation of each skinned hem skeleton chain to obtain the cleaned hem animation of each hem skeleton chain, which includes the chain head segment animation, the middle segment animation and the chain tail segment animation.

[0202] 208. While the skinned character skeleton executes the character animation, each hem skeleton chain also executes its own cleaned hem animation at the same time.

[0203] refer to Figure 2b , Figure 2b This is a top view of a game character equipped with a coat while performing character animation. The white arrow indicates a hem bone chain of the coat. It can be seen that when the game character in the game is performing the character animation, the hem of the coat flutters naturally following the game character's movements.

[0204] As can be seen from the above, this solution can set up the character skeleton of the game character, and N hem bone chains mounted on the character skeleton, the bone chain including the chain head segment, the middle segment and the chain tail segment; perform skinning and binding on the character skeleton of the game character and the N hem bone chains; make character animation for the skinned character skeleton, and generate blank frames according to the time parameters of each frame in the character animation; based on the blank frames, make chain head segment animation for the chain head segment of the target bone chain after skinning, the target bone chain is any hem bone chain; generate other bone chains according to the chain head segment animation of the target bone chain The chain head segment animation is generated according to the chain head segment animation of the skeleton chain, and the other skeleton chains are the skeleton chains other than the target skeleton chain in the N hem skeleton chains; the chain tail segment animation of the chain tail segment and the middle segment animation of the middle segment in the skeleton chain are generated; the waste frames of the hem animation of each skinned skeleton chain are cleaned up to obtain the cleaned hem animation of each skeleton chain, and the hem animation includes the chain head segment animation, the middle segment animation and the chain tail segment animation; while the skinned character skeleton executes the character animation, each hem skeleton chain also executes its cleaned hem animation at the same time.

[0205] Therefore, this solution improves the efficiency of animation production.
