[0002] In the field of three-dimensional graphics rendering, light and shadow effects are the key to creating visual realism. In the prior art, light and shadow effects can be generated through static normal maps and lighting models. The static normal map method requires first making a smooth normal model, and then passing the smooth normal model to the model that needs to be modified to adjust and change the model normal, and then generating light and shadow effects based on the adjusted normal. The lighting model method requires first making a high-polygon, high-detail high-poly model and a low-polygon model that needs to be adjusted to find the effect, and then using baking software to bake the details of the high-poly model into a normal map based on the normal direction of the low-poly model, and finally performing lighting calculations based on the normal map to generate light and shadow effects.
[0003] However, the production process of the normal model in the static normal map method is complicated, and the normal model needs to be manually adjusted in real time during the transmission process. The manual baking process of the normal map in the lighting model method is cumbersome and not suitable for rapid iteration and large-scale production. The lighting calculation is complex during runtime and has high requirements on hardware performance. In addition, the existing methods lack sufficient flexibility and real-time performance for dynamic scenes and real-time rendering. Summary of the invention

[0031] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme 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 only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.
[0032] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.
[0033] When generating the light and shadow effects of a model, the prior art includes two methods: static normal map and lighting model.
[0034] Static normal mapping means making a smooth normal model first, and then transferring the smooth model normal to the model that needs to be modified. During the transfer process, the smooth normal model needs to be adjusted in real time to ensure the best normal effect.
[0035] However, when using this method to achieve lighting effects, it is necessary to manually bake the normal map, which is a cumbersome process and not suitable for rapid iteration and large-scale production. It lacks sufficient flexibility and real-time performance for dynamic scenes and real-time rendering.
[0036] The lighting model means first making a high-polygon model with high polygon count and high details, then making a low-polygon model that needs to adjust the normal effect, and then using baking software to bake the details of the high-polygon model into a normal map, and finally passing the normal map into the tool to calculate the light and shadow information.
[0037] However, this method requires lighting calculations to be performed at runtime, which has high requirements on hardware performance and is not conducive to cross-platform compatibility. It also lacks sufficient flexibility and real-time performance for dynamic scenes and real-time rendering.
[0038] Based on this, the present application proposes a model effect processing method, which automatically calculates the position information of the character's bones based on an algorithm, fits the normals suitable for rendering, skips the time-consuming and labor-intensive process of manual baking and normal transfer, achieves smooth light and shadow effects, and improves the efficiency of light and shadow effect generation.
[0039] In one implementation, the method of the present application can be applied to a virtual model in a three-dimensional scene where the lighting angle changes in real time. The fitted normal of the virtual model can be fitted in the design phase, and previewable light and shadow effects can be generated based on the fitted normal in the design phase. Or, the lighting result can be obtained based on the fitted normal of the virtual model and real-time lighting in the running phase, and the lighting effect of the virtual model can be rendered based on the lighting result.
[0040] In the second implementation, the method of the present application can be applied to a virtual model in a two-dimensional scene with a fixed lighting angle and a fixed viewing angle or a virtual model in a three-dimensional display scene. In the design phase, the fitting normal of the virtual model is obtained, and the light and shadow calculation results are generated according to the fitting normal and the current lighting, and in the game running phase, the lighting effect of the virtual model is rendered based on the light and shadow calculation results.
[0041] Next, combine Figure 1 The model effect processing method of the present application is described. The method can be applied to game engines, such as Unreal Engine (UE) UE4, UE5, etc. Figure 1 As shown, the method includes:
[0042] S101. Generate a fitting normal vector of the target model based on position information of a plurality of preset bone nodes in the target model, wherein the preset bone nodes are bone nodes that are not coplanar with each other.
[0043] The target model may be a virtual model of a game character in different postures. In one possible implementation, normals may be generated for the virtual models of the game character in different postures to obtain fitted normal vectors of the virtual models in each posture. In another possible implementation, fitted normal vectors may also be generated for the virtual model of the game character in the initial posture or the binding posture.
[0044] The preset bone nodes may be at least three non-coplanar bone nodes in the virtual model, and the position information of the preset bone nodes may be the world space position coordinates of the preset bone nodes.
[0045] For example, if the virtual model is a human model or a humanoid model, three non-coplanar bone nodes can be determined at the head, waist and foot positions of the virtual model as preset bone nodes. The selection of preset bone nodes is not limited here, but the preset bone nodes can be dispersed in the virtual model to obtain a more reasonable fitting normal vector.
[0046] Optionally, the fitted normal vector can be the normal of each vertex on the surface of the target model, which is used to define the orientation of the vertex or face, and determines the angle and intensity of the light shining on the surface of the target model. The game engine can determine the position and angle of the light shining on the model based on the normal, and the position and angle of the light reflected or refracted on the vertex, so that the game engine can determine how to illuminate the target model. Among them, the normal is perpendicular to the local area of the target model surface. The fitted normal vector can be used to determine the way the light is reflected or refracted on the model, thereby affecting the light and shadow effects of the target model.
[0047] In a possible implementation, the spherical surface is smooth and has a uniform transition, so a sphere that wraps the target model can be fitted based on preset bone nodes, and then the fitting normal vector of the target model can be determined based on the normal of the sphere.
[0048] S102, determining an illumination result of the target model according to the fitted normal vector and the illumination vector of the target model in a preset scene, where the illumination result is used to characterize an illumination effect of the target model under the action of the illumination vector of the preset scene.
[0049] Among them, the illumination vector of the target model in the preset scene can describe the relative position relationship between the surface of the target model and the direction of the light source. According to the fitted normal vector of each vertex and the illumination vector in the preset scene, the illumination result of each vertex can be determined. The preset scene can be a design scene in the game design stage, or a game scene where the target model is currently located in the game running stage. Taking the game running stage as an example, there can be at least one light source in the game scene where the target model is currently located, and the illumination vector of the target model in the preset scene can describe the relative position relationship between the surface of the target model and the light source in the current game scene.
[0050] Optionally, the illumination result is used to characterize the illumination effect of the vertices of the target model under the action of the illumination vector of the preset scene. In a possible implementation, the illumination result can be the dot product result of the fitted normal vector of the vertex and the illumination vector, and the dot product result is used to characterize whether the fitted normal vector is the same as the illumination vector, thereby obtaining the degree of illumination of the model surface.
[0051] For example, when the fitted normal vector and the illumination vector are the same, the model surface will be affected by the illumination. When the fitted normal vector and the illumination vector are opposite, the model surface will not be affected by the illumination. Based on this, the brightness of the model surface can be adjusted according to the positive and negative value of the dot product result, thereby achieving a more realistic lighting effect.
[0052] As a possible implementation method, after the fitted normal vector of the target model is determined, the illumination vector can be changed in real time. At this time, the illumination result of the target model can be recalculated based on the new illumination vector and the fitted normal vector.
[0053] As another possible implementation method, when the illumination vector remains unchanged, the fitted normal vector of the target model is in the same coordinate system. In one possible implementation method, the user can adjust the coordinate system of the target model to adjust the direction of the fitted normal vector of the target model, thereby affecting the illumination effect of the target model.
[0054] For example, the initial coordinate system positive direction of the fitted normal vector of the target model is the positive direction of the X-axis. The X-axis can be rotated 0-360° on the Y-axis with the center of the circle through a rotation matrix to change the direction of the fitted normal vector, thereby affecting the lighting effect.
[0055] S103: Render and display the target model based on the illumination result.
[0056] The illumination result can characterize the brightness of each vertex of the target model. By rendering the target model based on the illumination result, the light and shadow effect of the target model under the action of the illumination vector of the preset scene can be obtained.
[0057] It should be noted that the above step S101 can be implemented in the design stage. After determining the fitted normal vector of the target model, if the illumination vector is fixed, steps S102 and S103 can be performed in the design stage to directly determine the illumination result of the target model based on the fitted normal vector and the illumination vector, and render and display the target model based on the illumination result. If the illumination vector is not fixed, steps S102 and S103 can be performed in the running stage to obtain the illumination result of the target model based on the fitted normal vector and the illumination vector.
[0058] Exemplarily, for a scene with a fixed illumination vector and a relatively fixed viewing angle, such as a scene for model preview display, the above steps S101-S103 can be performed in the design stage to obtain and save the rendering result of the target model.
[0059] In an embodiment of the present application, a fitting normal vector of the target model is generated based on position information of multiple preset bone nodes in the target model, wherein each preset bone node is a non-coplanar bone node. According to the fitting normal vector and the illumination vector of the target model in a preset scene, the illumination result of the target model is determined. The illumination result is used to characterize the illumination effect of the target model under the action of the illumination vector of the preset scene, and the target model is rendered and displayed based on the illumination result.
[0060] Compared with the prior art, the method of the present application does not require the user to manually bake the normals, nor does it require normal transfer. Instead, the fitting normal vector of the target model is calculated directly based on the position information of the preset bone nodes of the target model, eliminating the reliance on external maps, thereby reducing memory usage and data transmission. In addition, the method of the present application skips the normal baking process, saving more time and labor costs, speeding up the production process of the model's light and shadow effects, automatically calculating the fitting normal vector based on the position information of the bones, and also improving the repeatability and consistency of the production process. When applied to dynamic scenes and real-time rendering, the method of the present application does not need to re-bake or import a large amount of map resources, but instead adjusts the fitting normal vector in real time or performs real-time calculation based on the new illumination vector, thereby re-obtaining the illumination result of the target model, with better flexibility and real-time performance.
[0061] Furthermore, the process of generating the fitted normal vector of the target model based on the position information of multiple preset bone nodes in the target model includes:
[0062] Based on the position information of multiple preset bone nodes and the material processing module in the game engine, the fitting normal vector of the target model is generated.
[0063] The material processing module in the game engine is used to process material-related calculations. For example, the material processing module can be a material blueprint in the game engine, which is used to provide a visual interface so that users can create nodes in the material blueprint and achieve complex material effects by creating and modifying nodes. The material processing module can calculate the position information of multiple preset bone nodes of the target model to obtain the fitted normal vector of the target model.
[0064] In the embodiment of the present application, the material processing module directly performs calculation based on the position information of the preset bone nodes, which can eliminate the reliance on external normal maps, thereby reducing the use of memory and data transmission. In addition, the material processing module in the game engine directly calculates, so that the calculation process runs directly on the GPU, reducing the need for data transmission between the server and the client.
[0065] The following is a further explanation of the above-mentioned fitting normal vector of the target model obtained by fitting in the material processing module of the target model based on the position information of multiple preset bone nodes in the target model, such as Figure 2 As shown, the step includes:
[0066] S201. The position information of a plurality of preset bone nodes is transmitted to a material processing module, and the material processing module performs calculation based on the position information of each preset bone node to obtain a fitting sphere of a target model.
[0067] Taking the game engine UE4 as an example, create a C++ processing module in UE4 to automatically obtain the world position of the bone. Use the Get Bone Location By Name node to obtain the corresponding world space position according to the bone name, and use the Set MPC Vector Parameter Value node to pass the position information to the material processing module.
[0068] It is worth noting that the data calculated by the C++ processing module cannot be directly passed to the material processing module for calculation. At this time, the position information of multiple preset bone nodes can be passed to the material parameter set first, and then passed to the material processing module for subsequent calculation.
[0069] Optionally, the fitting sphere of the target model may be a sphere that encloses the entire target model. Figure 3 , is a schematic diagram of a target model and a fitting sphere provided in the present application. The target model is completely wrapped inside the fitting sphere, and the center of the fitting sphere is located inside the target model.
[0070] S202 , performing fitting calculation based on the normal vector of the fitting sphere and the target model to obtain a fitting normal vector of the target model.
[0071] The normal vector of the fitted sphere may be a vector from the center of the fitted sphere to the fitted sphere surface point A. The normal vector is perpendicular to the tangent plane of the fitted sphere point A and points to the outside of the spherical surface.
[0072] As a possible implementation, the normal vector of the fitting sphere can be modified to obtain the fitting normal vector of the target model. In another possible implementation, the normal vector of the fitting sphere and the initial normal of the target model can also be fitted and calculated to obtain the fitting normal vector of the target model.
[0073] The above process of transmitting the position information of multiple preset bone nodes to the material processing module includes:
[0074] The position information of the plurality of preset bone nodes is stored in a target container in the game engine, and the material processing module obtains the position information of the plurality of preset bone nodes from the target container.
[0075] The target container can be used to store the position information of the preset bone nodes. The target container is set in the game engine. In a possible implementation, the C++ processing module can obtain the position information of the preset bone nodes according to the names of the preset bone nodes, and store the position information of the preset bone nodes in the target container, so that the material processing module can obtain the position information of multiple preset bone nodes from the target container, and reduce the need for data transmission between the server and the client.
[0076] It is worth noting that the target container only stores information and does not change the content of the information. The target container can also be connected to other links in the design process. For example, the rendering process and the lighting process can also directly obtain information from the target container and perform calculations.
[0077] The following is a further description of the above calculation based on the position information of each preset bone node to obtain the fitting sphere of the target model, such as Figure 4 As shown, the above step S201 includes:
[0078] S401. Calculate based on the position information of each preset skeleton node to obtain the position of the target point, and use the position of the target point as the center position of the fitted sphere.
[0079] The preset bone nodes are at least three non-coplanar points. Based on the three non-coplanar points, a unique sphere can be fitted. Assuming that the position coordinates of the preset bone nodes are A(x1,y1,z1), B(x2,y2,z2) and C(x3,y3,z3), the position of the target point (x,y,z) can be calculated by solving the following set of equations.
[0080] (x1-x) 2 +(y1-y) 2 +(z1-z) 2 =r 2
[0081] (x2-x) 2 +(y2-y) 2 +(z2-z) 2 =r 2
[0082] (x3-x) 2 +(y3-y) 2 +(z3-z) 2 =r 2
[0083] Or the position of the target point can be obtained by solving the following set of equations.
[0084]
[0085] Among them, m and n are the normal vectors of the line passing through points A and B, and r is the radius of the sphere. After determining the normal vector and the radius of the sphere, the position of the center of the sphere can be determined based on the normal vector and the radius of the sphere.
[0086] S402: Calculate based on the position information of each preset bone node to obtain the length of the target radius, and use the length of the target radius as the radius of the fitted sphere.
[0087] After obtaining the center position (x, y, z) of the sphere, the radius of the fitted sphere can be calculated using the following formula.
[0088]
[0089] The center position and radius of the sphere can uniquely determine the fitting sphere. After the fitting sphere is determined, a fitting calculation can be performed based on the normal vector of the fitting sphere and the target model to obtain the fitting normal vector of the target model, such as Figure 5 As shown, the above steps include:
[0090] S501 , connecting the center of the fitted sphere and the first vertex of the target model to obtain a connecting line of the first vertex.
[0091] S502: Determine a fitted normal vector of the first vertex according to the connecting line and the normal vector of the fitted sphere.
[0092] Optionally, after obtaining the position of the center of the sphere, the normal vector N of any point P on the fitted sphere on the spherical surface can be calculated. The normal vector is perpendicular to the vector from the center of the sphere to the point P. The calculation method is shown in the following formula. Wherein, point O is the center of the sphere.
[0093]
[0094] The first vertex may be any point on the target model. When determining the fitted normal vector of the target model, all vertices of the target model may be traversed, and for each vertex, the vertex and the center of the fitted sphere are connected respectively, and the fitted normal vector of each vertex is determined based on the connecting line of each vertex and the normal vector of the fitted sphere.
[0095] Further, such as Figure 6 As shown, the process of determining the fitted normal vector of the first vertex according to the connecting line and the normal vector of the fitted sphere in the above step S502 includes:
[0096] S601: Determine a first normal vector that meets a first preset requirement with respect to the connecting line.
[0097] The first preset requirement may be the same direction as the connection line, or approximately parallel, for example, the distance between any two points on the connection line and the first normal vector is less than a preset distance threshold, and the distance difference is less than a preset distance difference threshold.
[0098] S602: Perform fitting calculation on the first normal vector and the connecting line to obtain a fitting normal vector of the first vertex.
[0099] By fitting and calculating the normal vectors on the fitted sphere and the connecting lines between each vertex and the center of the circle, the fitted normal vectors of each vertex of the target model can be obtained. Since the normal vectors of the sphere are uniform, the fitted normal vectors determined based on the normal vectors of the sphere and the connecting lines are also uniformly distributed.
[0100] The above process of fitting the first normal vector and the connecting line to obtain the fitting normal vector of the first vertex is as follows: Figure 7 As shown, including:
[0101] S701. Fit a first normal vector and a connecting line to obtain a first initial fitting normal vector.
[0102] S702: Determine the direction of a first initial fitting normal vector based on the first vertex to obtain a fitting normal vector of the first vertex.
[0103] The fitting of the first normal vector and the connecting line may be performed by taking the points of the first normal vector and the connecting line as a data point set, and performing fitting calculation on the data point set to obtain the first initial fitting normal vector.
[0104] As a possible implementation method, after determining the first initial fitting normal vector, the connecting line between the first vertex and the center of the circle can be extended to a straight line, the two intersection points M and N of the extended straight line and the fitting sphere are determined, and it is determined which of the two intersection points is closest to the vertex of the model. The direction of the vertex and the intersection point that is closer is used as the direction of the first initial fitting normal vector.
[0105] In the second implementation method of performing fitting calculation based on the normal vector of the fitted sphere and the target model to obtain the fitted normal vector of the target model, the normal of the target model can also be corrected based on the normal vector of the fitted sphere to obtain the fitted normal vector of the target model, such as Figure 8 As shown, the above step S202 includes:
[0106] S801, determining a second normal vector in the fitting sphere that satisfies a second preset condition with respect to a first target normal vector of the target model.
[0107] The first target normal vector may be a normal vector of any vertex in the target model. The second preset condition may be that the first target normal vector and the second normal vector have the same direction or are approximately parallel.
[0108] S802: Perform fitting calculation on the first target normal vector and the second normal vector to obtain a fitting normal vector of the target model.
[0109] By correcting the normal vector on the target model based on the second normal vector on the fitted sphere, the normal vector of the target model can be made more uniform, thereby achieving a smoother light and shadow effect.
[0110] The following is a further explanation of the above-mentioned fitting calculation of the first target normal vector and the second normal vector to obtain the fitting normal vector of the target model, such as Fig. 9 As shown, the above step S802 includes:
[0111] S901. Perform fitting calculation on the first target normal vector and the second normal vector to obtain a second initial fitting normal vector.
[0112] The fitting calculation of the first target normal vector and the second normal vector can be performed by treating the points on the first target normal vector and the points on the second normal vector as a data point set, and performing the fitting calculation based on the data point set to realize the correction of the first target normal vector and obtain the fitting normal vector of the target model.
[0113] S902: Determine the direction of the second initial fitting normal vector based on the direction of the first target normal vector to obtain a fitting normal vector of the target model.
[0114] The second initial fitting normal vector may be a fitting straight line, the direction of which depends on the direction of the first target normal vector. In a possible implementation, the direction with a smaller angle difference with the first target normal vector may be used as the direction of the second initial fitting vector.
[0115] After determining the fitted normal vector, the illumination result of the target model can be determined based on the fitted normal vector and the illumination vector of the target model, such as Fig.10 As shown, the above step S102 includes:
[0116] S1001. Perform dot multiplication processing on the fitted normal vector and the illumination vector of the target model to obtain the dot product result of each fitted normal vector.
[0117] Taking the UE4 game engine as an example, the Dot node in the material processing module can be used to perform dot multiplication processing on each fitted normal vector and illumination vector of the target model to obtain the dot product results of each fitted normal vector.
[0118] S1002: Binarize the dot product result to obtain the illumination result of the target model.
[0119] After binarization of the dot product result, the dot product result can be limited to a preset threshold range, such as a range of 0 to 0.5, to obtain the illumination result of the target model. The illumination result is rendered to obtain the light and shadow effect of the target model.
[0120] It should be noted that after the above-mentioned determination of the fitted normal vector, the fitted normal vector can also be adjusted to change the light and shadow effect of the target model.

[0121] In response to the normal adjustment operation, the fitted normal vector of the target model is adjusted to the target position to obtain a new fitted normal vector.
[0122] The normal adjustment operation may be an operation of adjusting the coordinate system of the fitted normal vector. After the user adjusts the coordinate system of the fitted normal vector in the graphical user interface, the game engine may determine the rotation matrix based on the adjustment angle, and then calculate the adjusted coordinate system and the positions of each fitted normal vector in the coordinate system based on the rotation matrix and the initial coordinate system.
[0123] The above process of determining the illumination result of the target model according to the fitted normal vector and the illumination vector of the target model in the preset scene includes:
[0124] Based on the new fitted normal vector and the illumination vector of the target model, an illumination result of the target model is generated.
[0125] After obtaining the new fitted normal vector, the new fitted normal vector and the illumination vector of the target model may be dot-multiplied and binarized to obtain the illumination result of the target model.
[0126] In the embodiment of the present application, by rotating the axis of the fitted normal vector, the target model light and shadow effects can be dynamically updated. In this process, there is no need to re-make the normal map or perform manual baking, which simplifies the process of generating the target model normal and improves the efficiency of generating light and shadow effects.
