Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

According to the method provided by the embodiment of the invention, when the morphing instruction is received, the mask layout can be directly loaded, the morphing animation is generated and displayed in the game by fusing the mask layout and the skeleton variation process, processing operations such as masking and the like on the mask layout are not needed, the calculated amount is reduced, the cost and the difficulty of the role morphing of the game are reduced, the too high workload of developers is avoided, and the generation efficiency of the morphing animation is improved.
An embodiment of the present invention provides a method for generating a character morphing animation, as shown in fig. 2A, the method includes:
201. and establishing a role model and a metamorphic model of the target game role.
The inventor realizes that the whole deformation of the game character in many games needs to be completed in a short time at present, therefore, when a developer of the game designs the deformation process of the game character, a plurality of Mask maps for showing each stage in the deformation process are drawn for the game character, the Mask processing is carried out on the plurality of Mask maps through an engine material node, thereby forming the deformation process of the game character, and when a player requests the deformation in the game, the deformation process is displayed, thereby realizing the deformation of the game character. In the process, the Mask map belongs to a set template, the effect of the game role change is determined, the process is only carried out according to the Mask, the change process of the common game role is delicate, a large number of Mask maps are needed for completely showing the change process, and the calculated amount of engine material nodes is tested. In addition, the art workload for making the Mask map is very large, and the Mask map is only deformed by simply changing the skin of the model, so that the deformation process is unnatural or the Mask map is likely to be cracked. Therefore, the invention provides a method for generating a character morphing animation, which constructs a skeleton variation process and a plurality of masking layouts, directly loads the masking layouts to be fused with the skeleton variation process when morphing is needed, can generate the morphing animation and directly display the morphing process without setting Mask maps in advance, not only reduces the art difficulty, programs the whole morphing process, reduces the performance calculation, shortens the self-making period of the morphing animation, but also makes the morphing animation more natural and realizes the morphing without dead angles.
In order to realize the method, the model when the game role is not changed and the model after the change are determined, so that the rendering of the stage model in the change process is realized, and a foundation is laid for the generation of a subsequent mask graph. The model of the non-transformed image of the target game role is the role model mentioned in the embodiment of the invention, and the model of the transformed image of the target game role is the transformed model mentioned in the embodiment of the invention. When the character model and the variant model are manufactured, the character model is obtained based on the basic image of the game character, and the variant of the character in the game is usually realized by a series of evolutions, changes and the like on the basic image, so the character model can be established firstly, and the variant model can be established on the basis of the character model. The specific process of establishing the role model and the metamorphic model is as follows: first, wiring is performed in accordance with the image of the target game character, and a character model is generated. And then, determining the changed image of the target game character, and mapping the changed image with the joint of the character model. In the actual application process, the character model and the metamorphic model generated after the target character image and the metamorphic image are wired can be as shown in fig. 2B. In fig. 2B, the left model is a character model, the right model is a morphing model, and lines formed on the surfaces of the two models are wirings. According to the wiring, a plurality of grids can be formed, so that the grids can be filled based on materials subsequently to realize the fusion of the model and the materials instead of simply changing the skin, the fusion is comprehensive and complete, the model and the materials are prevented from being cut apart, and the obtained deformation effect is better and natural. In order to ensure that joints, bones and the like between the character model and the metamorphic model are completely corresponding, so that the motion of the character model and the metamorphic model in the game is correct and the corresponding bones can be driven, the wiring of the character model and the metamorphic model on the corresponding parts needs to be ensured to be completely consistent. For example, referring to the triangle formed by the wiring in the circle in fig. 2C, the triangle is located at the knee of the character model, and the triangle also corresponds to the knee of the morph model. It should be noted that the present invention is only illustrated by using a triangle, in the practical application process, the wiring may also form a quadrangle, a pentagon, etc. on the model, and no matter what shape is formed, the shapes correspond to each other in the character model and the deformation model, so that the wiring of the two models can be ensured to be completely consistent. Next, the pitch between the wirings of the character model is changed using the joints as the fixed points, and a morphing model is obtained. The wiring number and the wiring mode of the transformer model can be consistent with those of the role model through the process, and the wirings of all parts are mutually corresponding, so that the role model and the transformer model are ensured to be consistent in wiring, the fusion deformation from the role model to the transformer model can be realized in the subsequent process, and the deformed transformer model is ensured to be correct in the subsequent operation.
After the role model and the transformer model are obtained through wiring, the role model and the transformer model need to be bound, and the requirement for fusing the two models subsequently is met. When the character model and the variant model are bound, because some bones are not possessed by the character model, but the variant model has, for example, a tail, a tip and the like, and the fusion process of the model requires that weight information of the character model and the variant model is mutually transmitted, and can be realized only if the bones are the same, at least one bone to be added needs to be obtained, the mapping position of the at least one bone to be added in the character model is determined, and the at least one bone to be added is added to the character model according to the mapping position. Wherein, at least one bone to be added, namely the bone which is included by the metamorphic model and not included by the character model. For example, assuming that the metamorphic model has more tails than the character model and the tails consist of 6 bones, the 6 bones are placed in the character model where the tails are wired at the tail vertebrae and skin is added to control the motion information of the tails. And then, establishing a mapping relation between the role model and the variant model based on the joints, and binding the role model and the variant model, namely binding the same joints between the role model and the variant model, so that the role model and the variant model are bound, and further realizing skin addition.
202. A plurality of montage layouts is created.
In the embodiment of the invention, after the generation of the skeleton change process is completed, the material establishment is started for each model, so that the skinning operation on the models is realized, and a plurality of skinning layouts are established. The material is required to be evolved along with the model, so the material also has an evolution process, a plurality of preset materials corresponding to the role model are required to be obtained, for each preset material in the preset materials, the material creation is carried out on the role model based on the preset material to obtain a creation result, the creation result is copied to the function node, and the material function of the role model is generated. And then, according to the same flow, repeating the process of executing the material function, and generating the material function for each preset material in the plurality of preset materials to obtain a plurality of material functions. And finally, converting the plurality of material functions into a plurality of Mongolian layouts. It should be noted that the plurality of preset materials also have a creation order, and the material function generation process needs to be sequentially executed according to the order, so that the generated plurality of montage layouts are correct in color change. In the process of actual application, after the creation result is generated, the creation result can be displayed to a developer for the developer to refer to and modify. When a confirmation instruction for the creation result is received, it may be determined that the developer feels that the creation result of the material is satisfactory, and the process of copying the authoring result may be continuously performed, or the confirmation by the developer may not be relied on, which is not specifically limited by the present invention.
It should be noted that, in the above step 201 and step 202, the generation process of the character model, the morphing model, and the mask map is described in detail, in the embodiment of the present invention, the generation process is executed before the morphing instruction is received, and after the morphing instruction is received, the model and the mask map may be directly obtained for use. In the process of practical application, after the change instruction is received, the generation process of the model and the mask diagram can be executed, and the model and the mask diagram can be fused in different modes in the change process of different times, so that various change operations are realized. The time of the color modeling model, the metamorphic model and the Mongolian layout is not particularly limited.
203. Receiving a change instruction, acquiring a role model and a change model of a target game role, determining a skeleton offset, and generating a skeleton change process from the role model to the change model based on the skeleton offset.
In the embodiment of the invention, after the character model and the morphing model are generated, since the morphing of the game character in the game usually needs to embody a morphing process, the interest and the impact of the morphing process can be embodied, therefore, after a morphing instruction is received, a skeleton morphing process for displaying the morphing process needs to be constructed based on the character model and the morphing model, and the process of the character model evolving to the morphing model is embodied. When the process is established, the character model and the metamorphic model need to be arranged at the same position for comparison, the difference between the two models is determined, and the difference is evolved according to time to form the process, so that the skeletal difference between the character model and the metamorphic model needs to be calculated as skeletal offset, and the skeletal offset is utilized to evolve the metamorphic process to generate the skeletal variation process. In the embodiment, the change instruction request is changed from the role model to the change model, and in the actual application process, the change instruction may also request to change from the change model to the role model, so that the bone change process and the material change process are fused in a reverse order subsequently.
When calculating the skeleton difference value, because the centers of gravity of the character model and the deformation model are different, in order to realize the comparison of corresponding parts between the character model and the deformation model, a preset skeleton standard point needs to be obtained, the position of the preset skeleton standard point mapped in the character model is used as a first reference point, the position of the preset skeleton standard point mapped in the deformation model is used as a second reference point, the second reference point is superposed with the first reference point, the character model and the deformation model are controlled to be superposed, so that the skeleton difference value between space points of the superposed character model and the appointed part of the deformation model is calculated, and the skeleton difference value is used as the skeleton offset. Wherein the bone offset is substantially a spatial vector. In the actual application process, the preset skeleton standard point can be generally selected as a pelvis, so that the pelvis set by the deformation model is moved to the position of the pelvis of the role model, and the position information of the skeleton when the final deformation is finished is determined. Then, displacement and rotation space information of corresponding bones between the character model and the metamorphic model can be obtained by using an xform (cloud form) command, and a bone difference value between the character model and the metamorphic model is calculated, so that a bone offset is obtained.
After the bone offset is calculated, the generation of the bone change process is initiated. Considering that the number of the space points forming the role model and the transformation model is large, if the space points are moved once to realize the comparison of each part between the two models, the evolution process of the part is formed, and a large amount of workload is involved, therefore, the two models can be divided into regions respectively, the comparison is performed according to the regions to generate the evolution process of the regions, and finally, the evolution processes of the regions are assembled to form the skeleton change process. In this way, firstly, the character model needs to be divided according to a plurality of preset parts to obtain a plurality of first model regions of the character model, and the metamorphic model continues to be divided according to a plurality of preset parts to obtain a plurality of second model regions of the metamorphic model. The preset part can be divided into a head, a hand, a chest and the like. Then, the first model region and the second model region of the same part are associated to generate a plurality of region groups, namely, the appearance before the transformation of each part and the appearance after the transformation are determined, so that the transformation process between the two is formed subsequently. Next, the bone difference value is recorded in the morphing controller for subsequent fusion of the contents included in the region group based on the morphing controller. In the process of practical application, at the same time point, one region group may be fused, or more than one region group may be fused, so that at least one preset change time point may be further set, and each preset change time point in the at least one preset change time point may correspond to at least one region group to be fused, that is, at this time point, which parts are required to be changed, for example, it is assumed that the whole change process needs to go through 3 seconds, and the change of the foot and the leg needs to be completed in the first second, so that when the preset change time point is 1, the corresponding region groups to be fused are also the foot and the leg.
After the above-described work is completed, the generation of the bone change process can be started. Specifically, the bone difference value may be recorded in a morphing controller, and based on the morphing controller, the model regions included in each of the plurality of region groups are fused to generate a bone change process. In addition, if at least one preset morphing time exists, for each preset morphing time point in the at least one preset morphing time point, at least one target area group to be fused corresponding to the preset morphing time point is determined, and the controller is started to fuse the at least one target area group to be fused to obtain a phase model of the preset morphing time point. By repeatedly performing the generation of the phase model, a bone change process can be generated. The change of the bone position of the corresponding region can be controlled according to the attributes for different regions based on the controller, so that the evolution process formed in the bone change process is richer and finer. If in the IK (Inverse Kinematics) state, the arm and leg length ratios need to be calculated separately and the length ratios are also added to the controller, the above fusion process can still be completed, so that the transformation can be achieved in both the FK (Forward Kinematics) and IK states.
It should be noted that, for some region groups that need to show details, the model regions included in the region groups may be continuously segmented into finer regions that need to show details, and the finer regions are finely segmented according to the requirements of the animation.
204. And loading a plurality of Mongolian layouts of the target game role, and generating a material change process by adopting the plurality of Mongolian layouts.
In the embodiment of the invention, after the plurality of masking layouts are created, as the changing process of the game role is a gradual progressive process and is not directly changed from one material to another material, in order to reflect the naturalness of the changing process of the material, the plurality of masking layouts are adopted to generate the changing process of the material, so that the changing process of the material is reflected in the animation. Specifically, when the material change process is generated, a plurality of mask layouts of the target game role are obtained. In the game, the change of the material at each time point in the whole change process is preset, so that the preset change time point is determined. For each preset morphing time point in the preset morphing time points, loading at least two target masking layouts indicated by the preset morphing time points in the multiple masking graphs, carrying out color sampling on the multiple masking layouts, fusing the at least two target masking layouts according to a preset color change value, and repeatedly executing the fusion process of the masking layouts respectively for the preset morphing time points to obtain a material change process. The mask map is a material map including the entire body of the game character.
In addition, various image qualities and configurations are provided in the game, the morphing process is limited in some configurations, and a careful morphing process is not needed, so that different numbers and different mask patterns can be selected to be loaded under different configured game environments, the morphing process is simplified, and the fit with a player computer is guaranteed. Furthermore, the body changing effect can be customized, the bone changing process and the material changing process are fused according to different modes, positions, time and the like, the body changing can be more random, and the experience of a player is improved.
205. And fusing the skeleton change process and the material change process to obtain the change animation of the target game role.
In the embodiment of the invention, after the material change process is generated, the bone change process and the material change process are not combined together, so the bone change process and the material change process are fused to obtain the change animation of the target game role. Specifically, when fusion is performed, first, a preset starting position is obtained, and the preset starting position is mapped on the character model. The preset starting position is also the position from which the material change starts, and the preset starting position can be the heart, the head and the footstep, and the preset starting position can be defined by the staff. And then, adopting a material change process, and taking a preset starting position as a starting point to perform rendering fusion on the bone change process to generate a morphing animation. The process of fusing the bone change process and the material change process is substantially to fill the grid formed by wiring in the bone change process by adopting materials, so that pixel points filled in the grid are consistent with pixel points of the materials in the material change process, and the whole fusion process can be realized by executing fusion codes in MatLayerblend (material layer mixing) nodes. For example, referring to fig. 2D, if a large area of light-colored material in the first model in fig. 2D is material a, and a large area of dark-colored material in the third model in fig. 2D is material B, when the bone change process and the material change process are fused, the weight of material a is 0.9, and the weight of material B is 0.1, the first model in fig. 2D can be obtained by fusion; the weight of material A is 0.7, and the weight of material B is 0.3, so that the second model in FIG. 2D can be obtained by fusion; a weight of 0.5 for material A and 0.5 for material B can be fused to obtain the third model in FIG. 2D. Wherein, the above mentioned weight is used to represent the proportion of the material in the whole model, the weight is constantly changing, and the changing process of the weight is strongly related to the changing process of the skeleton.
The whole process of generating the above-described morphing animation may be directly displayed in the game, or may be generated in advance, and the morphing animation may be displayed when a morphing command is received. The present invention does not specifically limit the generation timing of the morphing animation.
According to the method provided by the embodiment of the invention, when the morphing instruction is received, the mask layout can be directly loaded, the morphing animation is generated and displayed in the game by fusing the mask layout and the skeleton variation process, processing operations such as masking and the like on the mask layout are not needed, the calculated amount is reduced, the cost and the difficulty of the role morphing of the game are reduced, the too high workload of developers is avoided, and the generation efficiency of the morphing animation is improved.
