[0016] In the process of game production, action animations need to be made for characters so as to achieve flexible control of the characters. Currently, action animations for characters are made manually. However, when there are many characters, it takes a lot of time and manpower to make a set of action animations for different characters. For example, when making a game, some of the same actions will be applied to multiple different characters. If a set of actions is made for each character, the demand for resources and game memory will be huge. However, for characters with different bone structures, the same set of actions cannot be used directly. At this time, action redirection is needed to map the actions of the original bones to the current bones to achieve the function of action reuse.

[0017] The redirection technology provided in this manual is for humanoid characters, and the length, position, and structure of the bones must not deviate too much from the original action bones; in addition, the redirection technology only supports one-to-one mapping of bones, and can simply copy the original animation bones to the mapped corresponding bones. However, the redirection technology cannot realize the redirection function of complex bindings, and the bones cannot be well integrated, resulting in poor action accuracy.

[0018] Based on this, in this specification, an object processing method is provided. This specification also involves an object processing device, a computing device, a computer-readable storage medium and a computer program product, which are described in detail one by one in the following embodiments.

[0019] See also Figure 1 , Figure 1A flowchart of an object processing method provided according to an embodiment of the present specification is shown, which specifically includes the following steps.

[0020] Step 102: Determine first action data of a first virtual object and a second virtual object corresponding to the first virtual object.

[0021] Among them, the virtual object can be understood as an object virtually obtained by using computer technology; the virtual object can be a game object controlled by a game player (such as a game character, a mecha, a car, an airplane, etc.), the virtual object can be a 3D model, a 3D game model (such as an NPC, a 3D mecha), or the virtual object can be a model that moves in a virtual reality (VR) scene under the control of a game player (such as a character model, a shell, a bullet, an arrow, etc.); the first virtual object and the second virtual object can be understood as two different virtual objects.

[0022] The action data can be understood as the skeletal action data that controls the virtual object to perform specific actions. For example, the action data can be the action animation, skeletal action, etc. of the virtual object; the first action data is the action data corresponding to the first virtual object, and the second action data is the action data corresponding to the second virtual object.

[0023] Taking the application of the object processing method provided in this specification in the skeletal chain action redirection scenario as an example, the object processing method is explained. Among them, the virtual object can be a mecha model, and the action data is a skeletal animation. Based on this, considering that the mecha shapes are different, the bones used for binding are also very different; therefore, how to successfully map the skeletal animation to the corresponding target bone becomes a challenge; in response to this challenge, the object processing method provided in this specification adopts the idea of ​​skeletal chain mapping rather than skeletal mapping, which can realize the mapping of any number of bones such as one-to-many, many-to-one, and many-to-many for skeletal animation redirection. The source bones in a skeletal chain of the first mecha model and the target bones of the second mecha model can include any number of bones, and the skeletal chains of the two are matched to adapt to the redirection between bones of different skeletal structures.

[0024] Step 104: Determine the object skeleton chain of the second virtual object and the object skeleton chain attribute parameters of the object skeleton chain, and determine the initial action skeleton chain of the first action data and the action skeleton chain attribute parameters of the initial action skeleton chain.

[0025] A bone chain can be understood as a set of interconnected virtual bone structures, which are used to simulate and control the movement of 3D models (usually character models).

[0026] The object skeleton chain can be understood as the skeleton chain of the second virtual object, and the action skeleton chain can be understood as the skeleton chain corresponding to the first action data; the skeleton chain attribute parameters include but are not limited to the skeleton chain length, the number of object bones contained in the skeleton chain, and the length of the object bones, bone rotation value, moving direction, moving position and other data; the object skeleton chain attribute parameters are the skeleton chain attribute parameters of the object skeleton chain; the action skeleton chain attribute parameters are the skeleton chain attribute parameters of the action skeleton chain.

[0027] In one or more embodiments provided in this specification, since different parts of the virtual object have different actual conditions, different mapping calculation methods need to be adopted to achieve the maximum degree of action restoration. Based on this, it is necessary to determine various types of bone chains from the bone action and the target bone according to the bone type. The specific implementation method is as follows: The step of determining the object skeleton chain of the second virtual object and the object skeleton chain attribute parameters of the object skeleton chain, and determining the initial action skeleton chain of the first action data and the action skeleton chain attribute parameters of the initial action skeleton chain includes: Determine a plurality of action skeleton subchains from the action skeleton chain of the first action data, and determine action skeleton subchain attribute parameters of each action skeleton subchain, wherein the plurality of action skeleton subchains are obtained by segmenting the action skeleton chain according to preset skeleton types; Determine the object skeleton subchain corresponding to each of the action skeleton subchains from the object skeleton chain to be processed of the second virtual object, and determine the object skeleton subchain attribute parameters of each object skeleton subchain; Using a target action skeleton subchain among the multiple action skeleton subchains as the initial action skeleton chain, and using a target action skeleton chain attribute parameter corresponding to the target action skeleton subchain as the action skeleton chain attribute parameter, wherein the target action skeleton subchain is any one or more of the multiple action skeleton subchains; The target object skeleton subchain corresponding to the target action skeleton subchain in the object skeleton subchain is used as the object skeleton chain, and the object skeleton subchain attribute parameters of the target object skeleton subchain are used as the object skeleton chain attribute parameters.

[0028] Among them, the preset bone types include but are not limited to mobile bone type (Hip), normal bone type (Normal), control bone type (Controller), accessory bone type (Slot), etc.; the mobile bone type can correspond to the bone chain of legs, feet, hip joints and other parts; the normal bone type can correspond to the bone chain of head, torso and other parts; the control bone type can correspond to the bone chain of arms, palms and other parts; the accessory bone type can correspond to the bone chain of handheld accessories (such as weapons), back accessories (such as back) and other parts.

[0029] The bone sub-chain can be understood as the bone sub-chain of the legs, feet, head, torso, arms, handheld accessories, etc.

[0030] Following the above example, this solution classifies the bone chain types, dividing the source bone chain into multiple source bone sub-chains and the target bone chain into multiple target bone sub-chains according to different types; different types of bone chains will use different mapping calculation methods to achieve the maximum degree of motion restoration; this method has good scalability, and if there are new needs in the future, the required bone types can be added; the current bone types include four categories: Hip, Normal, Controller, and Slot.

[0031] Step 106: Determine the skeleton adjustment parameters based on the object skeleton chain attribute parameters and the action skeleton chain attribute parameters.

[0032] Bone adjustment parameters can be understood as parameters for adjusting the action bone chain.

[0033] In one or more embodiments provided in this specification, determining the skeleton adjustment parameters based on the object skeleton chain attribute parameters and the action skeleton chain attribute parameters includes: Determining the length of the action skeleton chain and the action skeleton lengths of the multiple action bones included in the action skeleton chain from the action skeleton chain attribute parameters; Calculate the action bone ratio parameters of each action bone and the action bone chain according to the action bone chain length and the action bone length; Determine the object bone chain length and the object bone lengths of the multiple object bones included in the object bone chain from the object bone chain attribute parameters; Calculate the object bone ratio parameter of each object bone and the object bone chain according to the object bone chain length and the object bone length; The bone rotation ratio of each action bone is calculated according to the action bone ratio parameter and the object bone ratio parameter, and the bone rotation ratio is determined as a bone adjustment parameter.

[0034] Using the above example, during the process of redirecting the bone chain, the bones need to be rotated. The rotation of the redirected bones is not simply rotating the copied source bones, but a new rotation value calculated based on the number of bone chains, bone length, etc. to adapt to characters of different heights and shapes. The specific execution steps are: 1. Determine all source bones in a source bone chain and the bone length of each source bone; and determine the source bone chain length of the source bone chain; based on the source bone chain length and bone length, calculate the bone length of the current source bone and the source bone proportion parameter of the entire source bone chain length; 2. Determine all target bones in a target bone chain and the bone length of each target bone; and determine the target bone chain length of the target bone chain; calculate the target bone ratio parameter of the current target bone length to the entire target bone chain length based on the target bone chain length and the bone length; 3. According to the source bone ratio parameters and the target bone ratio parameters, calculate the rotation ratio of all source bones in the source bone chain.

[0035] Subsequently, the action can be accurately mapped to the target bone according to the rotation value of the corresponding position of the source bone and the calculated rotation ratio.

[0036] In one or more embodiments provided in this specification, determining the skeleton adjustment parameters based on the object skeleton chain attribute parameters and the action skeleton chain attribute parameters includes: Determining the action bone lengths of the multiple action bones included in the action bone chain from the action bone chain attribute parameters; Determining object bone lengths of a plurality of object bones included in the object bone chain from the object bone chain attribute parameters; Determine a target action bone from the multiple action bones, and determine an associated object bone corresponding to the target action bone from the multiple object bones, wherein the target action bone is any one of the multiple action bones, and the associated object bones are one or more; According to the action bone length of the target action bone and the object bone length of the associated object bone, the initial movement adjustment parameter of the target action bone is adjusted to obtain the target movement adjustment parameter, and the target movement adjustment parameter is used as the bone adjustment parameter.

[0037] Among them, the action skeleton has a corresponding action skeleton controller, and the action skeleton controller can be understood as the controller corresponding to the action skeleton.

[0038] Using the above example. During the bone chain redirection process, since the character's basic skeleton has a large number of controllers, the redirection also realizes the mapping of arbitrary lengths of different bone axes; the character can map the controller's movement data from the original bone to any axis of the target bone; the character's movement length can also be mapped from the original animation movement to any length of the target axis. The specific implementation method is: 1. Determine all source bones in a source bone chain and the bone length of each source bone; and determine all target bones in a target bone chain and the bone length of each target bone; wherein each source bone has a corresponding controller; 2. Calculate the length ratio parameter of the source bone and the target bone according to the length of the source bone and the target bone; 3. According to the length ratio parameter, the movement data of the controller of the source bone is adjusted to obtain the adjusted movement data; wherein the movement data includes the movement direction, movement length, movement speed, target position of the bone, etc.

[0039] Subsequently, the action can be accurately mapped to any axis of the target bone based on the adjusted movement data.

[0040] It should be noted that this solution also supports operations such as mapping from a single controller to multiple controllers, thereby achieving correct mapping of the controllers.

[0041] In one or more embodiments provided in this specification, determining the skeleton adjustment parameters based on the object skeleton chain attribute parameters and the action skeleton chain attribute parameters includes: Determining the length of the action skeleton chain and the action skeleton lengths of the multiple action bones included in the action skeleton chain from the action skeleton chain attribute parameters; Calculate the action bone ratio parameters of each action bone and the action bone chain according to the action bone chain length and the action bone length; Determine the length of the object's skeleton chain from the object's skeleton chain attribute parameters; Based on the action bone ratio parameter, the action bone length and the object bone chain length, a scaling parameter of each action bone is calculated, and the scaling parameter is used as the bone adjustment parameter.

[0042] Using the above example, during the process of redirecting the skeleton chain, the skeleton needs to be scaled to adapt to characters of different heights and shapes. The specific steps are: 1. Determine all source bones in a source bone chain and the bone length of each source bone; and determine the source bone chain length of the source bone chain; based on the source bone chain length and bone length, calculate the bone length of the current source bone and the source bone proportion parameter of the entire source bone chain length; 2. Determine the target bone chain length of the target bone chain; 3. Calculate the scaling ratio of each source bone based on the source bone ratio parameter, the target bone length, and the source bone chain length; The source bones can then be scaled based on the scaling ratio to accurately map the action to the target bones.

[0043] It should be noted that this solution classifies the types of bone chains, and different types will use different mapping calculation methods to achieve the maximum degree of motion restoration. Therefore, the mapping calculation methods corresponding to different types of bones are: The mapping calculation method corresponding to Hip is: displacement calculation, scaling calculation, and rotation calculation of mapping animation; The mapping calculation method corresponding to Normal is: the rotation calculation of the mapping animation; The mapping calculation method corresponding to the Controller is: displacement calculation of mapping animation; The mapping calculation method corresponding to Slot is: displacement calculation and rotation calculation of mapping animation; Among them, the displacement calculation can be understood as the calculation method of the movement adjustment parameters in the above embodiment, the rotation calculation can be understood as the calculation method of the bone rotation ratio in the above embodiment, and the scaling calculation can be understood as the calculation method of the scaling ratio parameters in the above embodiment.

[0044] Step 108: adjusting the initial action skeleton chain based on the skeleton adjustment parameters to obtain a target action skeleton chain of the first action data.

[0045] The target action skeleton chain may be understood as an adjusted skeleton chain that matches the second virtual object.

[0046] Step 110: Mapping the first action data to second action data of the second virtual object according to the target action skeleton chain.

[0047] The second action data may be understood as action data matching the second virtual object.

[0048] In one or more embodiments provided in this specification, mapping the first action data to second action data of the second virtual object according to the target action skeleton chain includes: An action curve displacement parameter corresponding to the first action data is determined, and based on the action curve displacement parameter and the target action skeleton chain, the first action data is mapped to second action data of the second virtual object.

[0049] Using the above example, due to the different heights of different characters, the feet may not touch the ground during redirection. This method uses the method of correcting the Hip bone to deal with it. When redirecting, the position of the Hip bone will be superimposed with the configured animation curve displacement (i.e., the action curve displacement parameter) to ensure the correct position of the current mecha.

[0050] The object processing method provided by one or more embodiments of the present specification can use the object skeleton chain attribute parameters of the object skeleton chain and the action skeleton chain attribute parameters of the initial action skeleton chain of the first action data to calculate the skeleton adjustment parameters for the initial action skeleton chain, and use the skeleton adjustment parameters to adjust the initial action skeleton chain to obtain a target action skeleton chain that matches the object skeleton chain of the second virtual object; finally, use the target action skeleton chain to map the first action data to the second action data of the second virtual object, thereby achieving efficient creation of action animations for game characters, avoiding the problem of manually producing action animations that requires a lot of time and manpower costs, and reducing resource usage and game memory requirements.

[0051] The following combination Figure 2 , taking the application of the object processing method provided in this specification in the skeletal chain action redirection scenario as an example, the object processing method is further described. Figure 2 A processing flow chart of an object processing method provided by an embodiment of the present specification is shown, which specifically includes the following steps.

[0052] Step 202: Determine the source skeletal action of the source mecha model and the source skeletal chain corresponding to the source skeletal action, and determine the target skeletal chain of the target mecha model.

[0053] Step 204: According to the classification of the bone chain type, multiple source bone sub-chains are determined from the source bone chain, and corresponding mapping calculation methods are determined for various types of source bone sub-chains.

[0054] Specifically, this solution classifies the types of bone chains, and different types of bones will use different mapping calculation methods to achieve the maximum degree of motion restoration. The current bone types include four categories: Hip, Normal, Controller, and Slot.

[0055] Among them, the Hip type can correspond to the skeleton chains of legs, feet, hip joints, etc.; the Normal type can correspond to the skeleton chains of the head, torso, etc.; the Controller type can correspond to the skeleton chains of arms, palms, etc.; the Slot type can correspond to the skeleton chains of handheld accessories (such as weapons) and back accessories (such as the back), etc.

[0056] The mapping calculation method corresponding to different types of bones is: The mapping calculation method corresponding to Hip is: displacement calculation, scaling calculation, and rotation calculation of mapping animation; The mapping calculation method corresponding to Normal is: the rotation calculation of the mapping animation; The mapping calculation method corresponding to the Controller is: displacement calculation of mapping animation; The mapping calculation method corresponding to Slot is: displacement calculation and rotation calculation of mapping animation; Step 206: Calculate the bone adjustment parameters of each source bone based on the mapping calculation method.

[0057] The mapping calculation provided by this solution includes three parameter calculation methods, namely: displacement calculation, scaling calculation, and rotation calculation.

[0058] Among them, for the rotation calculation, the specific processing process is as follows: In the process of redirecting the bone chain, the bones need to be rotated. The rotation of the redirected bones is not simply to rotate the copied source bones, but to calculate the new rotation value based on the number of bone chains, bone length, etc. to adapt to characters of different heights and shapes. The specific execution steps are: 1. Determine all source bones in a source bone chain and the bone length of each source bone; and determine the source bone chain length of the source bone chain; based on the source bone chain length and bone length, calculate the bone length of the current source bone and the source bone proportion parameter of the entire source bone chain length; 2. Determine all target bones in a target bone chain and the bone length of each target bone; and determine the target bone chain length of the target bone chain; calculate the target bone ratio parameter of the current target bone length to the entire target bone chain length based on the target bone chain length and the bone length; 3. According to the source bone ratio parameters and the target bone ratio parameters, calculate the rotation ratio of all source bones in the source bone chain; Among them, for displacement calculation, the specific processing process is as follows: In the process of bone chain redirection, since the character's basic skeleton has a large number of controllers, the redirection also realizes the mapping of arbitrary lengths of different axes of the bones; the character can map the controller's movement data from the original bone to any axis of the target bone; the character's movement length can also be mapped from the original animation movement to any length of the target axis. The specific implementation method is: 1. Determine all source bones in a source bone chain and the bone length of each source bone; and determine all target bones in a target bone chain and the bone length of each target bone; wherein each source bone has a corresponding controller; 2. Calculate the length ratio parameter of the source bone and the target bone according to the length of the source bone and the target bone; 3. According to the length ratio parameter, the movement data of the controller of the source bone is adjusted to obtain the adjusted movement data; wherein the movement data includes the movement direction, movement length, movement speed, target position of the bone, etc.

[0059] It should be noted that this solution also supports operations such as mapping from a single controller to multiple controllers, thereby achieving correct mapping of the controllers.

[0060] Among them, for the scaling calculation, the specific processing process is as follows: In the process of redirecting the skeleton chain, the skeleton needs to be scaled to adapt to characters of different heights and shapes. The specific steps are as follows: 1. Determine all source bones in a source bone chain and the bone length of each source bone; and determine the source bone chain length of the source bone chain; based on the source bone chain length and bone length, calculate the bone length of the current source bone and the source bone proportion parameter of the entire source bone chain length; 2. Determine the target bone chain length of the target bone chain; 3. Calculate the scaling ratio of each source bone based on the source bone scale parameter, the source bone length, and the target bone chain length.

[0061] Based on this scale, each source bone can be scaled so that the original bone can be mapped to the target bone.

[0062] Step 208: Adjust the source skeleton based on the skeleton adjustment parameters, and use the adjusted skeleton to map the skeleton action to the target mecha model.

[0063] Specifically, after obtaining the rotation ratio corresponding to the source bone, the rotation value of the corresponding position of the source bone is adjusted according to the calculated rotation ratio to obtain the adjusted source bone, and the adjusted source bone is mapped to the target bone of the target mecha model.

[0064] According to the length ratio parameter, the movement data of the controller of the source bone is adjusted, and after the adjusted movement data is obtained, the adjusted movement data is mapped from the original bone to any axis of the target bone of the target mecha model. Or After scaling each source bone based on the scaling ratio to obtain an adjusted source bone, the adjusted source bone is mapped to the target bone of the target mecha model.

[0065] It should be noted that due to the inconsistent heights of different characters, the feet may not touch the ground during redirection; this method uses the method of correcting the Hip bone to deal with it; when redirecting, the position of the Hip bone will be superimposed with the configured animation curve displacement to ensure the correct position of the current mecha.

[0066] Based on the above steps, it can be seen that through this solution, the action data of a single mecha can be applied to all mechas, reducing the workload required to create new actions. During iteration, only the actions of a single mecha need to be updated to achieve overall replacement, which facilitates the rapid iteration of game development.
