[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0028] In the related art, for each type of action, an animation producer needs to produce corresponding animation data separately. When the types of actions reach a certain level, it will bring a huge workload to the action designers.

[0029] For example, when making a game, as a way to improve the player's gaming experience, it is necessary to make as many game animations as possible. Assuming that according to the game plot, there are archery actions, running actions, and running and shooting actions; the animation production staff needs to make a set of animations for the archery action, a set of animations for the running action, and a set of animations for the running and shooting actions.

[0030] Therefore, as the types of actions increase, the workload of animators will increase.

[0031] In view of this, an embodiment of the present application provides an animation production method applied to an electronic device, which reuses existing animations of a target object and splices them into a new animation to achieve the purpose of improving the efficiency of animation production.

[0032] The electronic devices mentioned above may include, but are not limited to, servers, smart phones, personal computers (PCs), tablet computers, personal digital assistants (PDAs), mobile Internet devices (MIDs), etc.

[0033] The operating system of the electronic device may be, but is not limited to, an Android system, an IOS (iPhone operating system) system, a Windows phone system, a Windows system, etc.

[0034] For the above electronic device, the present application embodiment also provides a structural diagram of the electronic device. Figure 1 As shown, the electronic device includes a memory 120 and a processor 130 .

[0035] The memory 120 and the processor 130 are electrically connected to each other directly or indirectly to achieve data transmission or interaction. For example, these components can be electrically connected to each other via one or more communication buses or signal lines.

[0036] The memory 120 may be, but is not limited to, a random access memory (RAM), a read only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable read-only memory (EEPROM), etc. The memory 120 is used to store computer executable instructions, and the processor 130 implements the above animation generation method when executing the computer executable instructions in the memory.

[0037] The processor 130 may be an integrated circuit chip with signal processing capabilities. The above-mentioned processor may be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it may also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components. The methods, steps and logic block diagrams disclosed in the embodiments of the present application may be implemented or executed. The general-purpose processor may be a microprocessor or the processor may also be any conventional processor, etc.

[0038] In view of the above animation generation method, the present application embodiment provides a step diagram of the animation generation method. Figure 2 The method includes various steps which are described in detail. Figure 2 As shown, the animation generation method includes:

[0039] Step S101, obtaining a first partial animation of a first animation and a second partial animation of a second animation.

[0040] The first animation corresponds to a first action of the target object, and the second animation corresponds to a second action of the target object.

[0041] Step S102: splice the first partial animation and the second partial animation to obtain a spliced ​​animation corresponding to the third action of the target object.

[0042] In addition, the target object may be, but is not limited to, a human object, an animal object, and a fictional object (eg, a monster in a game), etc.

[0043] For example, taking a human subject as an example, the first action can also be an archery action, and the second action can be a running action. Of course, depending on the specific scene, the first action and the second action can also be other types of actions, which are not specifically limited in the embodiments of the present application. The above-mentioned archery action and running action are only examples provided in the embodiments of the present application.

[0044] Those skilled in the art may also expand to actions such as jumping, martial arts, and climbing as needed, without having to make creative contributions based on the embodiments of the present application.

[0045] Correspondingly, the first partial animation may be the upper body of the animation corresponding to the archery action, and the second partial animation may be the lower body of the animation corresponding to the running action.

[0046] The electronic device splices the upper body of the animation corresponding to the archery action with the lower body of the animation corresponding to the running action, so as to obtain the animation corresponding to the action of running and shooting arrows.

[0047] Therefore, compared with the related art, which requires a separate animation to be produced for the action of running and shooting arrows, the animation generation method provided in the embodiment of the present application obtains a spliced ​​animation by reusing the first partial animation of the first animation and the second partial animation of the second animation. Since the existing animation is reused, the production efficiency of the animation is improved.

[0048] In addition, in the embodiment of the present application, in order to make the obtained spliced ​​animation coordinated in body proportion, the first animation and the second animation need to be animations of the same target object. And in order to make the obtained spliced ​​animation coordinated in action, the first animation and the second animation also need to have the same frame sequence.

[0049] The above-mentioned archery action and running action are also used as examples to illustrate that in order to make the final spliced ​​animation coordinated in terms of body proportion and action, firstly, the animation corresponding to the archery action and the animation corresponding to the running action need to belong to the same character object.

[0050] On the contrary, assuming that the animation corresponding to the archery action belongs to a character object of 1.8 meters, and the animation corresponding to the running action belongs to a character object of 1.5 meters, then if the animation of the 1.8-meter character object and the animation of the 1.5-meter character object are spliced ​​together, the problem of inconsistent body proportions will arise.

[0051] Therefore, in the embodiment of the present application, both the first partial animation and the second partial animation will carry the numbers of the target objects to which they belong, so that the animation production personnel can determine whether the two partial animations belong to the same object by the numbers when splicing them.

[0052] At the same time, if the animation corresponding to the archery action has 30 frames in total, and the animation corresponding to the running action has 30 frames in total, in order to coordinate the spliced ​​animation in terms of action, it is necessary to splice the partial animation of the first frame of the archery animation with the partial animation of the first frame of the running animation, splice the partial animation of the second frame of the archery animation with the partial animation of the second frame of the running animation, and so on, to obtain a 30-frame spliced ​​animation of running and archery.

[0053] In one implementation, the first animation is a skeletal animation with the second animation. It should be understood that skeletal animation is a type of model animation. In skeletal animation, the model has a skeleton structure composed of interconnected "bones", and animation is generated for the model by changing the orientation and position of the bones.

[0054] There is a parent-child relationship between the bones that make up the skeleton structure, which will lead to linkage when moving. Specifically, the movement of the parent node will drive the overall movement of the bones as child nodes, but the movement of the bones as child nodes will not affect the bones as parent nodes.

[0055] For example, Figure 3 In the human skeleton shown, the thigh 201 is the parent node of the calf 202. When the thigh 201 moves, the calf 202 moves together. Correspondingly, when the calf 202 moves, it does not affect the thigh 201.

[0056] Since the bones in the skeletal animation are linked to each other, when the first partial animation and the second partial animation are directly spliced ​​together, they will affect each other, and then the spliced ​​animation will not achieve the desired animation effect.

[0057] For example, taking the above-mentioned animation of archery and animation of running as an example, it is assumed that the upper body of the animation corresponding to the archery action is spliced ​​with the lower body of the animation corresponding to the running action to obtain a spliced ​​animation of running and archery.

[0058] However, due to the linkage between bones, when the lower body is running, it will affect the upper body's swaying; and when the upper body is shooting arrows, it needs to remain stable. If the upper body's partial animation is directly spliced ​​with the lower body's partial animation, it will cause the upper body to sway left and right when shooting arrows, and the animation effect of aiming at the target cannot be achieved.

[0059] Therefore, in the embodiment of the present application, for the skeletal animation, the spliced ​​animation needs to automatically offset the offset from the lower body. Therefore, in the implementation of the present application, the electronic device uses the first animation and the second animation as the animations to be split; for each animation to be split, the skeletal model corresponding to the animation to be split is obtained.

[0060] The target bone located at the splitting position splits the bone model into a first sub-model and a second sub-model.

[0061] The electronic device constructs a virtual skeleton, wherein the virtual skeleton includes a central skeleton, a first skeleton and a second skeleton, and the central skeleton is a parent node of the first skeleton and the second skeleton.

[0062] Furthermore, the electronic device connects the first sub-model with the target bone through the first bone, wherein the first bone serves as the parent node of the first sub-model; and connects the second sub-model with the target bone through the central bone and the second bone, wherein the central bone serves as the parent node of the second sub-model.

[0063] Finally, the electronic device splits each animation to be split from the connection position between the target bone and the first bone according to the entire bone model inserted into the virtual bone, so as to obtain the first partial animation and the second partial animation.

[0064] Below Figures 4A-4B Taking the skeleton model shown in the figure as an example, the role of the virtual skeleton is explained exemplarily. Figure 4A As shown, the target bone 301 is determined from the skeleton model, the connection between the target bone 301 and other bones is disconnected, and the Figure 4A The skeleton model shown is split into Figure 4B A first sub-model 302 and a second sub-model 303 are shown.

[0065] Then, construct Figure 5 The virtual skeleton shown in Figure 1 is shown in Figure 2. Figure 5 As shown, the virtual skeleton includes a central skeleton 400, a first skeleton 401 and a second skeleton 402, wherein the central skeleton 400 is the parent node of the first skeleton 401 and the second skeleton 402, that is, there is a parent-child relationship between the central skeleton 400 and the first skeleton 401 and the second skeleton 402.

[0066] Under this premise, if Figure 6 As shown, the first sub-model 302 is connected to the target skeleton 301 through the first skeleton 401, and the target skeleton 301 is connected to the second sub-model 303 through the central skeleton 400 and the second skeleton 402. In this way, a skeleton model with a virtual skeleton inserted is obtained.

[0067] like Figure 7 As shown, according to the skeleton model with the virtual skeleton inserted, the animation to be split is split from the connection position between the target skeleton 301 and the first skeleton 401, and the animation to be split is split into partial animations of the upper body 501 and the lower body 502; then, according to the splicing needs, the first partial animation and the second partial animation are selected from all the split partial animations for splicing.

[0068] like Figure 7 As shown, assuming that the target bone 301 rotates 30° clockwise, under the action of bone linkage, the central bone 400 and the first bone 401 rotate 30° clockwise together.

[0069] If the first skeleton 401 and the central skeleton 400 are connected by Figure 5 If the two skeletons 400 and 401 are directly connected in the manner shown, a 30° clockwise rotation of the central skeleton 400 will cause the first skeleton 401 to also rotate 30° clockwise.

[0070] However, at this time, the first skeleton 401 is connected to the first sub-model 302, but there is still a parent-child relationship between the first skeleton 401 and the central skeleton 400, which will cause the first skeleton 401 to rotate 30° counterclockwise, and then the two will cancel each other out, so that the first sub-model 302 in the spliced ​​animation will not be affected by the second sub-model 303.

[0071] in addition, Figure 7 The split position shown is only an example provided by the embodiment of the present application, and those skilled in the art can also insert virtual bones at other positions of the skeleton model and perform splitting as needed, such as the neck, shoulders, waist, etc.

[0077] In a possible implementation manner, the first animation and the second animation have the same frame sequence.

[0078] In a possible implementation manner, a split position of the first partial animation in the first animation is the same as a split position of the second partial animation in the second animation.

[0079] In a possible implementation, the first animation and the second animation are skeletal animations, and the acquisition module 601 is specifically used for:

[0080] The first animation and the second animation are used as animations to be split;

[0081] For each of the animations to be split, a skeleton model corresponding to the animation to be split is obtained, wherein the target skeleton located at the splitting position splits the skeleton model into a first sub-model and a second sub-model;
