[0003] At present, the traditional practice of attaching models in game scenes is that model makers make the attached models one by one, which has high production costs, and the relevant matching and modification processes of the attached models are cumbersome and time-consuming, seriously affecting the development progress. Alternatively, model makers make a large number of templates of attached models for splicing. However, when splicing, the relevant terrain cannot be completely matched, which will be interspersed with the scene, affecting the realism of matching with the environment. Summary of the invention

[0087] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0088] In order to generate an attachment model that can match the surface of a target terrain unit in a virtual game construction scene, an embodiment of the present application provides an attachment model rendering method in a virtual scene, by determining the target terrain unit from the game construction scene along the shooting direction of a virtual camera, and determining the target surface point for attaching the attachment model on the model surface of the target terrain unit, and then performing surface point diffusion based on the target surface point in the game construction scene to obtain multiple surface points, and generating multiple virtual attachment units at the positions of the multiple surface points in the game construction scene respectively, and merging the multiple virtual attachment units to generate an attachment model, and determining the positions of the multiple surface points according to the model surface of the target terrain unit, so that the generated attachment model can match the model surface of the target terrain unit, avoiding interlacing with the game construction scene, and increasing the realism of the match between the attachment model and the game construction scene.

[0089] The attached model rendering method in the virtual scene provided by the embodiment of the present application is explained in detail below with reference to the accompanying drawings through specific examples. The attached model rendering method in the virtual scene provided by the embodiment of the present application can be implemented by a computer device pre-installed with: an attached model rendering algorithm or detection software, by running the algorithm or software. The computer device can be, for example, a server or a terminal, and the terminal can be a user computer. Figure 1One of the flow diagrams of a method for rendering an attached model in a virtual scene provided in an embodiment of the present application; Figure 1 As shown, the method includes:

[0090] S101. In response to a scene building instruction, a game scene screen formed by shooting a game building scene with a virtual camera is displayed in a graphical user interface.

[0091] Among them, the game construction scene includes multiple terrain units.

[0092] S102: along the shooting direction of the virtual camera, determine a target terrain unit from the game scene, and determine a target surface point for attaching the model on the model surface of the target terrain unit.

[0093] In this embodiment, the scene building instruction indicates to build a virtual game scene in the graphical user interface, so that the game scene screen and multiple terrains formed by the game building scene can be displayed in the graphical user interface. The terrain unit mainly includes various terrain features and interactive mechanisms. For example, the terrain unit can be: plains, forests, deserts, waters, swamps, etc.

[0094] Game scene construction refers to an environment or scene isolated from the real world generated by computer technology. This environment can be completely fictional or a simulation of the real world. Game scene construction requires a large number of three-dimensional models to form a game scene. For the generation of attached models in the game scene, the position of the target surface point of the model surface of the target terrain unit under the current shooting direction is determined along the shooting direction of the virtual camera. The model surface of the target terrain unit can be the ground surface, wall surface, eaves surface, etc. in the game scene. According to the shooting direction of the virtual camera, the target surface point of the attached model is determined from the model surface of the target terrain unit.

[0095] S103, performing surface point diffusion based on the target surface point in the game scene to obtain multiple surface points.

[0096] S104: Generate a plurality of virtual attachment units at the positions of a plurality of surface points in the game construction scene, respectively, and merge the plurality of virtual attachment units to generate an attachment model.

[0097] Specifically, the position of the target surface point can be regarded as a reference position point, and position diffusion is performed based on the position coordinates of the target surface point. Multiple surface points are determined from the model surface of the target terrain unit in the game scene. For example, based on the position of the target surface point, the positions of multiple surface points are determined from the ground surface or the wall surface, and the positions of the multiple surface points are used to determine the range of attachment model generation.

[0098] Then, according to the positions of the multiple surface points, multiple virtual attachment units are generated respectively, and the multiple virtual attachment units are merged to generate an attachment model in the game building scene, wherein the attachment model can be a moss model, a mud model, a magma model, etc., and the display range of the attachment model is related to the positions of the multiple surface points, so as to achieve the generation of the attachment model by rendering on the ground surface or on the wall surface. For example, if the attachment model is a moss model, the moss model is rendered on the ground surface or on the wall surface.

[0099] In summary, the embodiment of the present application provides a method for rendering an attachment model in a virtual scene, including: in response to a scene construction instruction, displaying a game scene screen formed by shooting a game construction scene by a virtual camera in a graphical user interface, wherein the game construction scene includes multiple terrain units; along the shooting direction of the virtual camera, determining the target terrain unit from the game construction scene, and determining the target surface point for attaching the attachment model on the model surface of the target terrain unit; performing surface point diffusion based on the target surface point in the game construction scene to obtain multiple surface points; generating multiple virtual attachment units at the positions of the multiple surface points in the game construction scene, and merging the multiple virtual attachment units to generate an attachment model. The method of the present application generates a target surface point based on the model surface of the target terrain unit and the shooting direction of the virtual camera, thereby determining the reference position of the attachment model to be generated, performing surface point diffusion based on the target surface point as the reference, determining the positions of the multiple surface points, further determining the generation range of the attachment model to be generated, and finally generating the attachment model in the game construction scene to achieve matching with the model surface of the target terrain unit, avoiding interlacing with the game construction scene, and increasing the authenticity of the matching between the attachment model and the game construction scene.

[0100] Based on the method for rendering an attached model in a virtual scene provided in the above embodiment, the embodiment of the present application provides another possible implementation of the method for rendering an attached model in a virtual scene by determining the position of a target surface point. Figure 2 The second flowchart of a method for rendering an attached model in a virtual scene provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, along the shooting direction of the virtual camera, a target terrain unit is determined from the game scene, and a target surface point for attaching the attachment model is determined on the model surface of the target terrain unit, including:

[0101] S201. Send a first ray to a game construction scene along a shooting direction of a virtual camera, so as to perform collision detection on the game construction scene by using the first ray.

[0102] S202: If the first ray hits the model surface of the target terrain unit, determine the target surface point.

[0103] In this embodiment, the position of the virtual camera in the game construction scene and the shooting direction of the virtual camera are first determined, and starting from the position of the virtual camera, a first ray is emitted toward the game construction scene along the shooting direction of the virtual camera, and a collision detection is performed on the game construction scene. If it is detected that the first ray hits the model surface of the target terrain unit, the coordinates of the hitting point are recorded as the position coordinates of the target surface point.

[0104] Among them, the first ray is recorded as K, and the first ray K is expressed as: K=P1+V1*X, wherein P1 represents the position of the virtual camera, V1 represents the shooting direction of the virtual camera, and X represents the distance of the first ray. When it is detected that the first ray collides with the model surface of the target terrain unit in the game construction scene, the coordinates of the hitting point, that is, the coordinates of the target position point, are recorded to obtain the target surface point P.

[0105] It should be noted that if the first ray hits the ground in the game scene, the model surface of the target terrain unit is the ground; if the first ray hits the wall in the game scene, the model surface of the target terrain unit is the wall. There is no restriction on the model surface of the target terrain unit.

[0106] In the method provided in this embodiment, a first ray is emitted to the game construction scene along the shooting direction of the virtual camera, so as to perform collision detection on the game construction scene using the first ray, and if the first ray hits the model surface of the target terrain unit, the target surface point is determined. By emitting the first ray to the game construction scene, the point where the first ray hits the model surface of the target terrain unit is used as the target surface point, so as to use the target surface point as a reference to determine the generation range of the attached model.

[0107] Optionally, the embodiment of the present application provides another possible implementation of the attached model rendering method in a virtual scene by determining multiple surface points. Figure 3 A schematic diagram of a visualized target surface point provided in an embodiment of the present application. Surface point diffusion is performed based on the target surface point in the game scene to obtain multiple surface points, including:

[0108] According to the preset radius range and the target surface point, surface point diffusion is performed based on the target surface point in the game scene to obtain multiple surface points.

[0109] In this embodiment, a visual spherical model is generated at the location of the target surface point, such as Figure 3 As shown, the position of the target surface point is Figure 3 The positions of the small and medium ball markers are located on the surface of the wall. The positions of the target surface points are visualized to obtain a ball model with the position of the target surface point as the sphere center. The size of the preset radius range is determined according to the radius r of the ball model.

[0110] According to the radius r of the ball model, the surface point diffusion is performed based on the position of the target surface point to obtain a preset radius range, and then the positions of multiple surface points within the preset radius range are determined from the game construction scene.

[0111] Optionally, an embodiment of the present application further provides another possible implementation of a method for rendering an attached model in a virtual scene. Figure 4 A third flow chart of a method for rendering an attached model in a virtual scene provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, according to the preset radius range and the target surface point, the surface point diffusion is performed based on the target surface point in the game scene to obtain multiple surface points, including:

[0112] S301. According to a preset radius range and a target surface point, a plurality of initial surface points within a preset radius range are determined from a game construction scene.

[0113] S302: Filter multiple initial surface points to obtain multiple surface points.

[0114] In this embodiment, after a plurality of initial surface points within a preset radius range are determined from the game construction scene according to the preset radius range and the target surface point, the plurality of initial surface points can be further screened. For example, by using a preset position coordinate range, if there is an initial surface point whose position coordinate is not within the preset position coordinate range, the initial surface point is filtered out; or, by using a preset number of surface points, if the number of the plurality of initial surface points is greater than the number of the preset surface points, the initial surface points are randomly filtered out so that the number of the filtered initial surfaces is less than the number of the preset surface points.

[0115] By filtering a plurality of initial surface points, a plurality of surface points are obtained, and the shape customization of the attached model is realized.

[0116] Optionally, based on the above embodiment, the embodiment of the present application further provides another possible implementation of the attached model rendering method in the virtual scene by determining multiple initial surface points. Figure 5 A fourth flowchart of a method for rendering an attached model in a virtual scene provided in an embodiment of the present application is provided. Figure 6 A schematic diagram of multiple initial surface points provided in an embodiment of the present application. Figure 5 As shown, according to the preset radius range and the target surface point, multiple initial surface points within the preset radius range are determined from the game construction scene, including:

[0117] S401: Generate a target plane range parallel to a preset reference plane according to a preset radius range and a target surface point.

[0118] In this embodiment, if the position of the target surface point is expressed as P(x, y, z), wherein the x-axis is the horizontal direction in the game construction scene, the y-axis is the front-to-back direction in the game construction scene, and the z-axis is the vertical direction in the game construction scene, and the preset reference plane is the plane perpendicular to the z-axis, then the position of the target surface point is moved vertically upward along the z-axis direction by a preset radius range, i.e., the radius r of the ball model, to obtain the center position of the target plane range, and the coordinates of the center position are expressed as P(x, y, z+r), and then the target plane range is constructed with the center position as the center and the preset radius range as the radius, as shown in FIG. Figure 6 shown.

[0119] S402: Taking multiple random points within the target plane as starting points, vertically emitting multiple second rays toward the game construction scene, so as to perform collision detection on the game construction scene using the multiple second rays.

[0120] S403: Determine the surface points hit by the multiple second rays in the game construction scene as multiple initial surface points.

[0121] Specifically, the coordinates of multiple random points T within the target plane satisfy the following coordinate range:

[0122] P(xr,yr,z+r) <T(x,y,z)<P(x+r,y+r,z+r)

[0123] Then, starting from the coordinates of the multiple random points, multiple second rays are emitted vertically downward in a loop, and the surface points hit by the multiple second rays in the game scene are determined as the positions of the multiple initial surface points. The multiple second rays can hit the ground surface or the wall surface. The positions of the generated multiple initial surface points are related to the topography of the model surface of the target terrain unit. The multiple initial surface points can be recorded as T1, T2, T3, ..., Tn.

[0124] In the method provided in this embodiment, a target plane range parallel to a preset reference plane is generated according to a preset radius range and a target surface point, and multiple random points within the target plane range are used as starting points to emit multiple second rays vertically to the game construction scene, so as to perform collision detection on the game construction scene using multiple second rays, and determine the surface points hit by multiple second rays in the game construction scene as the positions of multiple initial surface points. By determining multiple initial surface points, the generation range of the attached model can be further determined.

[0125] The embodiment of the present application also provides another possible implementation of the attached model rendering method in the virtual scene by filtering multiple initial surface points. Figure 7 A fifth flow chart of a method for rendering an attached model in a virtual scene provided in an embodiment of the present application is shown in FIG. Figure 7As shown, multiple initial surface points are filtered to obtain multiple surface points, including:

[0126] S501, generating a target surface patch parallel to a preset reference plane and having a preset pattern according to a preset pattern, a preset radius range and a target surface point.

[0127] S502: Filter multiple initial surface points according to the target face to obtain multiple surface points.

[0128] In this embodiment, the preset pattern may be a black and white pattern, which is used to filter a plurality of initial surface points and determine the shape of the attached model.

[0129] According to the preset pattern, the preset radius range and the target surface point, a parallel and preset reference plane is generated, and a target surface patch with the preset pattern is generated, wherein the target surface patch includes a black and white pattern.

[0130] Optionally, the plurality of initial surface points are filtered according to the grayscale value of each pixel point corresponding to a preset pattern in the target patch to obtain the plurality of surface points.

[0131] Specifically, taking multiple random points in the target patch as starting points, multiple second rays are emitted vertically toward the game scene. However, when emitting multiple second rays, it is necessary to determine whether each random point emits a second ray based on the grayscale value of each pixel corresponding to a preset pattern.

[0132] For example, if the grayscale value of the color pixel corresponding to the preset pattern in the target patch T(x, y, z) is less than the preset grayscale threshold, the second ray is not emitted, which can be expressed by the following formula:

[0133] C T(x,y,z) <C?0:1

[0143] S602: According to a preset radius range, the initial face patch is translated along a direction perpendicular to a preset reference plane to obtain a target face patch.

[0144] In this embodiment, an initial facet perpendicular to a preset reference plane is generated with the position of the target surface point as the center, and then the initial facet is moved upward by a value corresponding to the preset radius range along a direction perpendicular to the preset reference plane according to a preset radius range to obtain a target facet, and the coordinates of the target facet are also P(x, y, z+r).

[0145] Optionally, before step S602, the method further includes:

[0146] Adjust the size of the initial patch.

[0147] Specifically, according to the rendering requirements of the attached model in the virtual scene, the size of the initial face patch can be adjusted to obtain the initial face patch after the size adjustment.

[0148] Then, according to the preset radius range, the resized initial patch is translated along a direction perpendicular to the preset reference plane to obtain a target patch.

[0149] In the method provided in the embodiment of the present application, an initial patch with a preset pattern is generated on the target surface point according to a preset pattern, and then the initial patch is translated along a direction perpendicular to a preset reference plane according to a preset radius range to obtain a target patch. The method is used to filter multiple initial surface points according to the preset pattern in the target patch to achieve shape customization of the attached model.

[0150] Optionally, the embodiment of the present application also provides another possible implementation of the method for rendering an attached model in a virtual scene by determining multiple surface points.

[0154] S701: Calling a retopology function of a preset digital content software to merge multiple virtual attachment units to generate an initial attachment model.

[0155] In this embodiment, virtual attachment units of the same size are generated at the positions of multiple surface points in the game construction scene. The size of the virtual attachment unit can be adjusted. For example, if the attachment model is a moss model, the size of the virtual attachment unit also determines the thickness of the moss when the moss model is generated.

[0156] Specifically, the retopology function Compact Mesh of the preset digital content creation software (DCC) is called to perform a model Boolean operation on multiple virtual attachment units, and then the overlapping surfaces of the multiple virtual attachment units are removed to form a combined model with only different parts of the combined surfaces of the multiple virtual attachment units, that is, the multiple virtual attachment units are merged to generate an initial attachment model, such as Fig.10 As shown, Fig.10 The PCG in the text stands for Production Code Generation, which is displayed as an identifier in the schematic diagram provided by the preset digital content software and has no impact on the content of this solution.

[0157] S702: Rendering the initial attachment model according to a preset attachment type map to generate an attachment model.

[0158] Specifically, the following schematic diagram takes the attachment model as a moss model as an example, the preset attachment type map is a preset moss map, and the initial attachment model is processed using the preset digital content software to obtain the initial attachment model UV, such as Fig.11 As shown, the preset moss map is then assigned to the initial attached model UV to generate the attached model.

[0159] Model UV is a concept in computer graphics that describes the two-dimensional texture coordinate system obtained after the three-dimensional model surface is unfolded. By mapping the texture map to the UV coordinate system of the model surface, the texture map and color of the model surface can be controlled, thereby achieving a more realistic rendering effect. Model UV is usually composed of the vertex coordinates and texture coordinates of the triangular patch, which can be automatically generated or manually edited.

[0160] Optionally, the initial attachment model is rendered according to a texture map of a preset attachment type and a material map of a preset attachment type to generate an attachment model.

[0161] Specifically, a texture map of a preset attachment type and a material map of a preset attachment type are assigned to the initial attachment model UV to generate an attachment model, so that the surface of the attachment model has a texture of the preset attachment type and a material of the preset attachment type.

[0162] Optionally, before step S702, the method further includes:

[0163] Make shape adjustments to the initially attached model.

[0164] According to the preset attachment type map, the initial attachment model after shape adjustment is rendered to generate the attachment model.

[0165] Specifically, the shape of the initial attachment model is adjusted so that the shape of the initial attachment model is within a preset radius, and then the shape-adjusted initial attachment model is rendered according to a preset attachment type map to generate the attachment model.

[0166] Optionally, before step S702, the method further includes:

[0167] Perform face reduction processing on the triangular facets of the initial attached model;

[0168] According to the preset attachment type map, the initial attachment model after the surface reduction process is rendered to generate the attachment model.

[0169] Specifically, the initial attachment model is subjected to surface reduction processing using a preset virtual engine to obtain the initial attachment model after surface reduction processing, such as Fig.12 As shown, the initial attachment model after the surface reduction process is rendered according to the preset attachment type map to generate the attachment model.

[0170] In the method provided in the embodiment of the present application, the retopology function of the preset digital content software is called to merge multiple virtual attachment units to generate an initial attachment model; the initial attachment model is rendered according to the preset attachment type map to generate an attachment model, thereby obtaining an attachment model with a customized shape that matches the surface.

[0171] The embodiment of the present application also provides another possible implementation of the method for rendering an attached model in a virtual scene by generating a first insert model. Fig.13 A schematic diagram of a first insert model provided in an embodiment of the present application, wherein the method further includes:

[0172] Generate a first insert model on the surface of the attached model.

[0173] In this embodiment, a surface extraction operation is performed on the attached model in a direction perpendicular to the preset reference plane. For example, a surface extraction operation is performed on the attached model in the z-axis direction to determine the model surface on which the first insert needs to be generated. The determination formula is as follows:

[0174]

[0175] Among them, M (z) Expressed as the z-axis coordinate on each model surface, It represents the threshold value on the z-axis, thereby determining the model surface for generating the first insert model.

[0176] It should be noted that the present invention is also applicable to the model surface in the x-axis or y-axis direction, and the first insert model in the x-axis or y-axis direction can be generated, such as Fig.13 As shown, the first insert model can be a fluffy grass model.

[0177] The embodiment of the present application also provides another possible implementation of the method for rendering an attached model in a virtual scene by generating a second insert model. The method also includes:

[0178] A second insert model is generated at the connection area between the attached model and the target terrain unit in the game construction scene.

[0179] In this embodiment, there is a gap in the connection area between the attached model and the target terrain unit in the game construction scene. Therefore, decals can be added to the connection area between the attached model and the target terrain unit by using the decal function in the preset digital content software to be used as occlusion adjustment for the seam.

[0180] Among them, the decal function is used to add additional two-dimensional images or textures to the surface of the game scene to enhance visual details and realism. Decals can be used to simulate graffiti on the wall, cracks on the ground, mud stains on vehicles or scars on characters, etc. There is no need to redraw or modify the original three-dimensional virtual model, which greatly saves resources and development time, while increasing the diversity and richness of attached models and target terrain units.

[0181] Then, a color grayscale recognition method can be used to generate a second insert model at the location of the decal, or the second insert model can be directly added by manual placement, and the details can be further adjusted and optimized on the attached model, wherein the second insert model can also be a fluffy grass model.
