Description

Technical Field

[0001] The present application relates to the technical field of computer and animation data processing, and in particular to an animation data processing method, device, program product, medium and electronic device. Background Art

[0002] In games or applications with face-pinching functions, the face-pinching system can usually only adjust the character's face shape in a personalized way, but it is rare to adjust the height of the character model to achieve the function of pinching people. Even face-pinching systems that can achieve the "pinching" effect usually encounter problems. For example, after adjusting the character's appearance, if the original animation data continues to be used, an animation model that is inconsistent with the world space may be generated, resulting in inaccurate animation data processing. If animation data needs to be re-produced for the character after the appearance adjustment, it will take a lot of art work, which is generally limited by the cost and the final package size. The height adjustment can only select a few fixed height templates. Based on this, how to achieve flexible character model height adjustment without bringing too much art workload is a technical problem that needs to be solved urgently. Summary of the invention

It should be understood that the objects used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those shown or described.

[0042] Figure 1 A schematic diagram of an exemplary system architecture to which the technical solution of the embodiments of the present application can be applied is shown.

[0043] like Figure 1As shown, the system architecture may include terminal devices (such as Figure 1 The embodiment of the present invention is a schematic diagram of a mobile phone 101, a tablet computer 102, and a portable computer 103 shown in FIG. 1 ), a network 104, and a server 105. The network 104 is a medium for providing a communication link between the terminal device and the server 105. The network 104 may include various connection types, such as a wired communication link, a wireless communication link, and the like.

[0044] In one embodiment of the present application, after the terminal device sends the target skeleton model in the initial posture obtained after adjusting the original skeleton model in the initial posture to the server 105, the server 105 obtains the reference displacement data of the pelvic bone in the target skeleton model in the initial posture, obtains the reference distance data between the pelvic bone and the root bone in the target skeleton model in the initial posture, and obtains the actual distance data between the pelvic bone and the root bone in the target skeleton model in the animation posture. Finally, the server 105 determines the theoretical displacement data for adjusting the overall position of the target skeleton model in the animation posture to the adaptive position of the world coordinate system based on the reference displacement data and the reference distance data and the actual distance data.

[0045] In the present embodiment, the theoretical displacement data is determined by referring to the displacement data, the distance data, and the actual distance data between the pelvic bone and the root bone in the target skeletal model under the animation posture, so that the overall position of the target skeletal model under the animation posture can be further adjusted to the adaptation position of the world coordinate system through the theoretical displacement data. In this way, the original skeletal model (i.e., the target skeletal model) after adjustment can be avoided from being inconsistent with the world space under the animation posture (such as the phenomenon of the skeletal model and the ground in the world space intersecting), thereby improving the accuracy of the animation data processing. From another perspective, since the scheme proposed in the present application can avoid the original skeletal model after adjustment from being inconsistent with the world space under the animation posture, it is no longer necessary to re-edit the animation data for the various target skeletal models obtained after the original skeletal model after adjustment, thereby greatly reducing the workload of animation art and improving the efficiency of animation data processing, such as, while realizing the function of flexibly adjusting the height of the role model without bringing too much art workload.

[0046] It should be noted that the animation data processing method provided in the embodiment of the present application can be executed by the server 105, and accordingly, the animation data processing device is generally arranged in the server 105. However, in other embodiments of the present application, the terminal device can also have similar functions as the server 105, so as to execute the animation data processing solution provided in the embodiment of the present application.

[0047] It should also be noted that Figure 1 The number of terminal devices, networks and servers in the description is only illustrative. According to the implementation requirements, the server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. The terminal can be a smart phone, tablet computer, laptop computer, desktop computer, smart speaker, smart watch, etc., but is not limited to this, and this application does not limit it here.

[0048] It should be explained that cloud computing as described above is a computing model that distributes computing tasks on a resource pool composed of a large number of computers, so that various application systems can obtain computing power, storage space and information services as needed. The network that provides resources is called a "cloud". The resources in the "cloud" are infinitely expandable in the eyes of users, and can be obtained at any time, used on demand, and expanded at any time. By establishing a cloud computing resource pool (referred to as a cloud platform, generally referred to as an IaaS (Infrastructure as a Service) platform, various types of virtual resources are deployed in the resource pool for external customers to choose to use. The cloud computing resource pool mainly includes: computing devices (virtualized machines, including operating systems), storage devices, and network devices.

[0049] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0050] First of all, it should be noted that the technical solution proposed in this application is mainly used in game production or animation production scenarios. In game production or animation production scenarios, it is necessary to design related animation characters, such as animated characters, etc. Specifically, the animation character mainly includes two parts: bone (Bone) and skin (Skinned Mesh), which is generally produced by bone skinning animation technology.

[0051] The basic principle of skeleton skinning animation is to control each bone and joint first, and then match the skin with each bone and joint. In skeleton skinning animation, a character consists of a single mesh model as skin and a skeleton model organized in a certain hierarchy. The skeleton model describes the structure of the character. Just like the different parts in joint animation, the skeleton model in skeleton skinning animation forms a hierarchical structure according to the characteristics of the character. Adjacent bones are connected by joints and can move relative to each other. By changing the angle and displacement between adjacent bones, the skeleton model that makes up the character can make different actions and achieve different animation effects. The skin is a mesh covering the skeleton model to define the appearance of the character. The skin here is not a fixed rigid mesh, but a deformable mesh that can change under the influence of the skeleton model. Each vertex that makes up the skin will be affected by one or more bones. When the skin vertex is affected by multiple bones, different bones determine the influence weight of the skin vertex according to the geometric and physical relationship with the skin vertex. This weight can be calculated by modeling software or set manually. By calculating the weighted sum of the influence of different bones on the skin vertex, the correct position of the skin vertex in the world coordinate system can be obtained. The keyframes in the animation data generally store the position, orientation and other information of the skeleton model. The new position and orientation of each skeleton model at a certain moment can be determined by interpolating between two adjacent keyframes in the animation sequence. Then, according to the bone index and corresponding weight information stored in each vertex of the skin mesh that affects it, the new position of the vertex can be calculated, thus realizing the deformation animation of a single skin mesh driven by the skeleton model.

[0052] Figure 2 A flowchart of an animation data processing method according to an embodiment of the present application is shown, and the animation data processing method can be executed by a device having a computing processing function. Figure 2 As shown, the animation data processing method at least includes steps 220 to 280, which are described in detail as follows:

[0053] Step 220, obtaining displacement data of the pelvic bone in the target skeleton model in the initial posture as reference displacement data, wherein the target skeleton model in the initial posture is a skeleton model after the original skeleton model in the initial posture is adjusted.

[0054] In one embodiment of the present application, before obtaining the displacement data of the pelvic bone in the target skeletal model in the initial posture, the following steps may also be performed: Figure 3 Steps shown.

[0055] See also Figure 3, shows a flow chart of a method before obtaining displacement data of the pelvic bone in the target skeletal model in the initial posture according to an embodiment of the present application. Specifically, it includes steps 211 to 212:

[0056] Step 211, in response to the scaling operation on the original skeleton model in the initial posture, obtain the target skeleton model in the initial posture.

[0057] Step 212, adjusting the pelvic bone position in the target skeletal model in the initial posture to the first pelvic bone position, so as to adjust the overall position of the target skeletal model in the initial posture to an adaptive position of the world coordinate system.

[0058] In the present application, the target skeleton model may be obtained after the original skeleton model is deformed, for example, the target skeleton model is obtained by pinching the original skeleton model, and the original skeleton model may be the initially designed skeleton model.

[0059] In the present application, the original skeleton model may have an initial posture, such as a standing posture. When the original skeleton model is pinched and pinched, the leg bones of the original skeleton model may be lengthened or shortened, and the arm bones of the original skeleton model may be lengthened or shortened. The present application does not limit the specific method of pinching and pinching.

[0060] In the present application, the original skeleton model in the initial posture may be scaled, so as to pinch the original skeleton model to obtain the target skeleton model in the initial posture. Therefore, the target skeleton model in the initial posture is the skeleton model obtained after adjusting (i.e. scaling) the original skeleton model in the initial posture.

[0061] It should be noted that the control operation may be performed by directly applying a finger on a touch display screen, or may be performed by applying a mouse on a non-touch display screen.

[0062] In the present application, after adjusting the original skeleton model in the initial posture to the target skeleton model in the initial posture, the shape of the skeleton model changes, thereby causing the overall position of the skeleton model in the world coordinate system to change. For example, after lengthening the legs of the skeleton model, the feet of the skeleton model change from being in contact with the ground in the world space to being interlaced with the ground in the world space. For another example, after shortening the legs of the skeleton model, the feet of the skeleton model change from being in contact with the ground in the world space to being separated from the ground in the world space.

[0063] Based on this, the pelvic bone position in the target skeleton model in the initial posture can be adjusted to the first pelvic bone position to adjust the overall position of the target skeleton model in the initial posture to the adaptive position of the world coordinate system, for example, the feet of the target skeleton model in the initial posture are adjusted from being interspersed with the ground in the world space to being in contact with the ground in the world space, or, the feet of the target skeleton model in the initial posture are adjusted from being separated from the ground in the world space to being in contact with the ground in the world space.

[0064] It can be understood that the first pelvic bone position is the position of the pelvic bone in the target skeleton model in the world coordinate system under the initial posture.

[0065] In such Figure 2 In one embodiment of step 220, the displacement data of the pelvic bone in the target skeletal model in the initial posture is obtained, which can be performed as follows: Figure 4 Follow the steps shown.

[0066] See also Figure 4 , shows a detailed flow chart of obtaining displacement data of the pelvic bone in the target skeletal model in the initial posture according to an embodiment of the present application. Specifically including steps 221 to 222:

[0067] Step 221, determining the pelvic bone position in the original skeleton model in the initial posture as the second pelvic bone position.

[0068] Step 222: Calculate the displacement data of the pelvic bone in the target skeleton model in the initial posture according to the first pelvic bone position and the second pelvic bone position.

[0069] Specifically, in this embodiment, the second pelvic bone position may refer to the position of the pelvic bone in the original skeleton model in the world coordinate system in the initial posture.

[0070] Furthermore, after determining the first pelvic bone position and the second pelvic bone position, the first pelvic bone position and the second pelvic bone position may be subtracted to obtain displacement data of the pelvic bone in the target skeleton model in the initial posture.

[0071] It should be noted that the displacement data includes two aspects, one is the displacement size, and the other is the displacement direction. For example, after lengthening the legs of the skeleton model in a standing posture, the pelvic bones in the skeleton model need to be adjusted along the positive direction of the Z axis of the world coordinate system. Therefore, the displacement direction can be the positive direction of the Z axis.

[0072] Continue to refer to Figure 2 , step 240, obtaining the distance data between the pelvic bone and the root bone in the target skeleton model under the initial posture as reference distance data.

[0073] In such Figure 2 In one embodiment of step 240, the distance data between the pelvic bone and the root bone in the target skeleton model in the initial posture is obtained, which can be performed as follows: Figure 5 Follow the steps shown.

[0074] See also Figure 5 , shows a detailed flow chart of obtaining the distance data between the pelvic bone and the root bone in the target skeleton model in the initial posture according to an embodiment of the present application. Specifically including steps 241 to 242:

[0075] Step 241, determine the root bone position in the target skeleton model in the initial posture as the first root bone position.

[0076] Step 242: Calculate the distance data between the pelvic bone and the root bone in the target skeleton model in the initial posture according to the first pelvic bone position and the first root bone position.

[0077] It should be noted that, in this embodiment, since the first pelvic bone position is the position of the pelvic bone in the target skeletal model in the world coordinate system in the initial posture after the position is adjusted, the first root bone position must also be the position of the root bone in the target skeletal model in the world coordinate system in the initial posture after the position is adjusted.

[0078] It can be understood that if the first pelvic bone position is the position of the pelvic bone in the target skeletal model in the world coordinate system in the initial posture before the position is adjusted, then the first root bone position must also be the position of the root bone in the target skeletal model in the world coordinate system in the initial posture before the position is adjusted.

[0079] After determining the first pelvic bone position and the first root bone position, the first pelvic bone position and the first root bone position may be subtracted to obtain distance data between the pelvic bone and the root bone in the target skeleton model in the initial posture.

[0080] In order to make those skilled in the art better understand the present application, Figure 6 Provide explanation.

[0081] See also Figure 6 , showing a demonstration diagram of adjusting the original skeleton model in the initial posture to the target skeleton model in the initial posture according to an embodiment of the present application.

[0082] like Figure 6As shown, skeleton model 601 is the original skeleton model in a standing posture (i.e., the original skeleton model in the initial posture). By scaling the skeleton model (i.e., lengthening the leg bones of the skeleton model), skeleton model 602 (i.e., the target skeleton model in the standing posture) is obtained. At this time, the position of the pelvic bone A remains unchanged. Further, by adjusting the position of the pelvic bone A in the skeleton model 602, skeleton model 603 (i.e., the target skeleton model in the standing posture after the position is adjusted) is obtained. It can be seen from the figure that the displacement data of the pelvic bone A in the target skeleton model in the standing posture (i.e., the reference displacement data) is H1, and the distance data between the pelvic bone A and the root bone B in the target skeleton model in the standing posture (i.e., the reference distance data) is L1.

[0083] Continue to refer to Figure 2 , step 260, obtaining the distance data between the pelvic bone and the root bone in the target skeleton model under the animation posture as the actual distance data.

[0084] In the present application, the target skeleton model in the animation posture can be a skeleton model that completes various animation postures after being driven by animation data, for example, the target skeleton model in a squatting posture, and also for example, the target skeleton model in a jumping posture.

[0085] In one embodiment of the present application, before obtaining the distance data between the pelvic bone and the root bone in the target skeletal model under the animation posture, the following steps may also be performed: Figure 7 Steps shown.

[0086] See also Figure 7 , shows a flow chart of a method before obtaining the distance data between the pelvic bone and the root bone in the target skeleton model under the animation posture according to an embodiment of the present application. Specifically, it includes steps 251 to 252:

[0087] Step 251, obtaining original animation data for driving the original skeleton model to realize animation posture.

[0088] Step 252: reuse the original animation data on the target skeleton model to obtain the target skeleton model in the animation posture.

[0089] In the present application, the original animation data records data for driving the original skeleton model to realize various animation postures. The original animation data is reused on the target skeleton model, which can be to associate the original animation data with the target skeleton model to drive the target skeleton model to realize various animation postures, thereby obtaining the target skeleton model under the animation posture.

[0090] It should be noted that in the present application, since the target skeleton model is obtained after the original skeleton model is deformed, if the target skeleton model is driven by the original animation data to realize various animation postures, it is bound to cause the target skeleton model to be inconsistent with the world space under the animation posture. For example, when the target skeleton model is a skeleton model after the legs of the original skeleton model are elongated, the feet of the target skeleton model in the squatting posture are interlaced with the ground in the world space. Therefore, it is necessary to adjust the overall position of the target skeleton model in the world coordinate system under the animation posture according to the theoretical displacement data in the subsequent animation data processing.

[0091] In the present application, after the original animation data is reused in the target skeleton model, the overall position of the target skeleton model in the world coordinate system under the animation pose can be adjusted according to the theoretical displacement data, thereby avoiding the situation where the original skeleton model after adjustment is inconsistent with the world space under the animation pose. Therefore, there is no need to re-edit the animation data for the various target skeleton models obtained after the original skeleton model is adjusted, which can greatly reduce the workload of animation art and improve the efficiency of animation data processing. For example, it can realize the function of flexible adjustment of the character model's height without bringing too much art workload.

[0092] In such Figure 2 In one embodiment of step 260, the distance data between the pelvic bone and the root bone in the target skeletal model under the animation posture is obtained, which can be performed as follows: Figure 8 Follow the steps shown.

[0093] See also Figure 8 , shows a detailed flow chart of obtaining the distance data between the pelvic bone and the root bone in the target skeleton model under the animation posture according to an embodiment of the present application. Specifically including steps 261 to 263:

[0094] Step 261, determining the pelvic bone position in the target skeletal model under the animation posture as the third pelvic bone position.

[0095] Step 262, determining the root bone position in the target skeleton model under the animation posture as the second root bone position.

[0096] Step 263, calculating the distance data between the pelvic bone and the root bone in the target skeleton model under the animation posture according to the third pelvic bone position and the second root bone position.

[0097] It should be noted that, in the present embodiment, the third pelvic bone position is the position of the pelvic bone in the target skeletal model in the world coordinate system under the animation pose, and the second root bone position is the position of the root bone in the target skeletal model in the world coordinate system under the animation pose. After determining the third pelvic bone position and the second root bone position, the distance data between the pelvic bone and the root bone in the target skeletal model under the animation pose can be obtained by subtracting the third pelvic bone position and the second root bone position.

[0098] It should be noted that since the posture of the target skeleton model in the initial posture is different from the posture of the target skeleton model in the animation posture, the distance data between the pelvic bone and the root bone in the target skeleton model in the initial posture (i.e., the reference distance data) and the distance data between the pelvic bone and the root bone in the target skeleton model in the animation posture (i.e., the actual distance data) will also be different. For example, the distance data between the pelvic bone and the root bone in the target skeleton model in the squatting posture will be smaller than the distance data between the pelvic bone and the root bone in the target skeleton model in the standing posture.

[0099] Continue to refer to Figure 2 , step 280, based on the reference displacement data and the reference distance data, determine theoretical displacement data through the actual distance data, and the theoretical displacement data is used to adjust the overall position of the target skeleton model in the animation posture to an adaptive position of the world coordinate system.

[0100] In such Figure 2 In one embodiment of step 280, based on the reference displacement data and the reference distance data, the theoretical displacement data is determined by the actual distance data, which can be performed as follows: Fig. 9 Follow the steps shown.

[0101] See also Fig. 9 , shows a detailed flow chart of determining theoretical displacement data through the actual distance data based on the reference displacement data and the reference distance data according to an embodiment of the present application.

[0102] Specifically including step 281 to step 282:

[0103] Step 281, determining the ratio data between the actual distance data and the reference distance data.

[0104] Step 282, calculating the theoretical displacement data according to the reference displacement data and the ratio data.

[0105] Further, in an embodiment of the present application, after determining the theoretical displacement data through the actual distance data based on the reference displacement data and the reference distance data, the following steps may also be performed:

[0106] According to the theoretical displacement data, the target overall position of the target skeleton model in the animation posture is determined, and the target overall position is the adapted position of the target skeleton model in the world coordinate system in the animation posture.

[0107] In order to make those skilled in the art better understand the present application, Figure 6 and Fig.10 Provide explanation.

[0108] See also Fig.10 , shows a demonstration diagram of adjusting the position of the target skeleton model under the animation posture according to an embodiment of the present application.

[0109] like Figure 6 and Fig.10 As shown, the skeleton model 1001 is a target skeleton model in a squatting posture (i.e., a target skeleton model in an animation posture) obtained by driving the target skeleton model 603 in a standing posture (i.e., a target skeleton model in an initial posture) with the original animation data. The distance data (i.e., the actual distance data) between the pelvic bone and the root bone in the target skeleton model in the squatting posture is L2.

[0110] Since the target skeleton model is obtained after the original skeleton model is deformed, the feet of the skeleton model 1001 obtained by driving the target skeleton model with the original animation data appear to be interlaced with the ground in the world space. At this time, the overall position of the skeleton model 1001 (i.e. the target skeleton model in the squatting posture) in the world coordinate system needs to be adjusted. In one case, if the overall position of the skeleton model 1001 in the world coordinate system is adjusted directly according to the displacement data of the pelvic bones in the target skeleton model in the initial posture (i.e. the reference displacement data H1), the situation of over-adjustment will occur, such as Fig.10 In another case, if the reference displacement data H1 and the reference distance data L1 are used to determine the theoretical displacement data H2 through the actual distance data L2, and the overall position of the skeleton model 1001 in the world coordinate system is adjusted according to the theoretical displacement data H2, then over-adjustment will not occur. Fig.10 The foot in the skeleton model 1003 is just in contact with the ground in the world space.

[0111] Further, in one embodiment of the present application, after determining the target overall position of the target skeleton model under the animation posture, the following steps may be performed: Fig.11 Steps shown.

[0112] See also Fig.11, shows a flow chart of a method after determining the target overall position of the target skeleton model under the animation posture according to an embodiment of the present application. Specifically comprising steps 291 to 293:

[0113] Step 291, obtaining skin mesh vertex data, skin weight data and model texture data corresponding to the original skeleton model.

[0114] Step 292, determining a target animation model through the target skeleton model in the animation pose, the skin mesh vertex data, the skin weight data and the model texture data.

[0115] Step 293: Display the target animation model at the target overall position in the world coordinate system to achieve the animation posture of the target animation model.

[0116] In the present application, after the original animation data is reused in the target skeletal model, the target overall position of the target skeletal model in the world coordinate system under the animation pose is determined according to the calculated theoretical displacement data, and the target animation model determined by the target skeletal model under the animation pose, the skin mesh vertex data, the skin weight data and the model mapping data is displayed at the target overall position of the world coordinate system. This can avoid the situation where the target animation model is inconsistent with the world space under the animation pose, and improve the accuracy of animation data processing.

[0117] In order to make those skilled in the art better understand the present application, Fig.12 and Fig.13 A specific embodiment is used for description.

[0118] Reference Fig.12 , shows an overall flow chart of an animation data processing method according to an embodiment of the present application. Specifically, it includes steps 1201 to 1206:

[0119] Step 1201, adjust the height of the original skeleton model in the initial posture to obtain the target skeleton model in the initial posture.

[0120] Step 1202, obtaining the displacement data H1 of the pelvic bone in the target skeleton model on the Z axis in the initial posture.

[0121] Step 1203, obtaining the distance data L1 between the pelvic bone and the root bone in the target skeleton model in the initial posture on the Z axis.

[0122] Step 1204, driving the target skeleton model to implement animation actions through the animation data corresponding to the original skeleton model, and obtaining the target skeleton model in the animation posture.

[0123] Step 1205, obtaining the distance data L2 between the pelvic bone and the root bone in the target skeleton model in the animation posture on the Z axis.

[0124] Step 1206, calculating the displacement data H2=H1×(L2 / L1) of the pelvic bone in the target skeleton model on the Z axis under the animation posture.

[0125] See also Fig.13 , showing a comparison diagram of the effects of a target animation model according to an embodiment of the present application.

[0126] like Fig.13 As shown, without using the animation data processing solution proposed in the present application, if the overall position of the target skeletal model of the stretched leg in the world coordinate system is adjusted according to the reference displacement data, the foot 1301 of the target animation model will be separated from the ground in the world space. If the overall position of the target skeletal model of the stretched leg in the world coordinate system is adjusted according to the calculated theoretical displacement data, the foot 1303 of the target animation model will just touch the ground in the world space.

[0127] When using the animation data processing solution proposed in the present application, if the overall position of the target skeletal model with the reduced legs in the world coordinate system is adjusted according to the reference displacement data, the foot 1302 of the target animation model will appear to be interspersed with the ground in the world space. If the overall position of the target skeletal model with the reduced legs in the world coordinate system is adjusted according to the calculated theoretical displacement data, the foot 1304 of the target animation model will appear to be just in contact with the ground in the world space.

[0128] It can be seen that, through the animation data processing scheme proposed in the present application, on the one hand, it is possible to avoid the original skeleton model (i.e., the target skeleton model) after adjustment from being inconsistent with the world space under the animation posture (such as the skeleton model and the ground in the world space intersecting), thereby avoiding the situation where the final target animation model is inconsistent with the world space, and improving the accuracy of animation data processing. On the other hand, since the scheme proposed in the present application can avoid the original skeleton model after adjustment from being inconsistent with the world space under the animation posture, it is no longer necessary to re-edit the animation data for the various target skeleton models obtained after the original skeleton model is adjusted, thereby greatly reducing the workload of animation art and improving the efficiency of animation data processing, for example, while realizing the function of flexibly adjusting the height of the character model, it does not bring too much art workload.
