RVT (Runtime Virtual Texturing) is an emerging and efficient terrain rendering technology that is gradually being widely used in game development. The sampling process of RVT is mainly carried out on the XY plane, which works well on the horizontal plane, but will cause serious texture stretching when sampling in the Z direction.

[0003] Currently, the method based on the viewing angle and the normal direction of the terrain surface is often used to remove or adjust areas that may cause severe texture stretching. This method calculates the angle between the normal and the line of sight of each terrain fragment. When the angle exceeds a certain threshold, the fragment is removed or specially processed.

[0004] However, the above method will cause visual discontinuity, affect the overall visual effect, and increase additional overhead, affecting rendering performance. Summary of the invention

[0012] In a second aspect, an embodiment of the present application further provides a terrain rendering device in a game, comprising: an acquisition module, a determination module, and a rendering module;

[0015] The determination module is used to determine the target position information of each vertex according to the height offset information of each vertex and the original position information;

[0016] The rendering module is used to render and display the intersection area of ​​the target terrain and the target object according to the target position information of each vertex.

[0017] In a third aspect, an embodiment of the present application provides an electronic device comprising: a processor, a storage medium and a bus, wherein the storage medium stores machine-readable instructions executable by the processor.

The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various 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.

[0040] 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.

[0041] First, some professional terms that may be involved in the following embodiments are briefly explained:

[0042] Shader: A program used to generate images in computer graphics, coloring objects on the screen.

[0043] Material: A collection of properties used to define the appearance of a 3D model surface. In a game engine, it is generally composed of a shader and a texture. It contains information describing the color, texture, reflectivity, transparency, gloss, and other information of the model surface, as well as properties that control how the model reflects, refracts, and scatters light.

[0044] UV coordinates: A coordinate system used to describe texture mapping. Texture mapping is a technique for applying a texture image to a flat or curved surface, which can make the appearance of a 3D model surface more realistic and detailed. When performing texture mapping, it is necessary to map the pixel coordinates in the texture image to the surface of the 3D model, which requires the use of texture coordinates. Texture coordinates are usually a two-dimensional coordinate system that describes the pixel position in the texture image. When performing texture mapping, the shader will look up the corresponding color value in the texture image according to the texture coordinates corresponding to each pixel, and apply it to the model surface to achieve the effect of texture mapping.

[0045] Sampling coordinates: A coordinate system used to sample texture images. When performing texture mapping, the shader needs to obtain the corresponding pixel color value from the texture image, which requires the use of sampling coordinates to specify the pixel position to be obtained.

[0046] Sampling coordinates are usually an extension of texture coordinates and can be two-dimensional, three-dimensional, or higher-dimensional coordinates. When sampling textures, the shader will look up the corresponding color value in the texture image based on the sampling coordinates corresponding to each pixel, and apply it to the model surface to achieve the effect of texture mapping.

[0047] World Space Coordinates: World space coordinates refer to positions in a global coordinate system. They are absolute coordinates relative to the entire scene, as opposed to local space coordinates (such as model local coordinates).

[0048] Normal: A normal is a vector perpendicular to a surface, used to describe the direction of the surface. In graphics rendering, normals are used to calculate lighting and reflection effects.

[0049] Seam: A seam is the boundary between different textures or planes. In triplanar mapping, discontinuities may appear in the seam area and need to be smoothed to avoid visual artifacts.

[0050] Linear interpolation (Lerp): Linear interpolation is a mathematical method for smooth transition between two values. In graphics rendering, it is often used to blend different texture sampling results.

[0051] Temporal Anti-Aliasing (TAA): Temporal anti-aliasing is a technique that reduces jagged edges by sampling and averaging in the temporal dimension. It uses information from multiple frames to smooth image edges.

[0052] Dither Temporal Anti-Aliasing (DitherTAA): DitherTAA combines dithering and temporal anti-aliasing techniques to achieve smoother texture effects and reduce visual artifacts and jagged effects by accumulating and averaging over time.

[0053] Next, the relevant background of this plan is explained:

[0054] In the field of game development, the seamless connection between terrain and 3D models is one of the key factors to improve visual quality and enhance immersion. With the continuous improvement of hardware performance and the increasing requirements of players for graphic details, traditional terrain rendering technology has been unable to meet the needs of complex and changing scenes. As an emerging and efficient terrain rendering technology, RVT has gradually been widely used in game development.

[0055] RVT greatly improves rendering efficiency and detail performance by storing terrain texture information in the form of virtual textures, sampling and rendering them at runtime. Specifically, the core principle of RVT is to preprocess the terrain's height map, normal map, and other related texture information into virtual textures, and then perform real-time sampling from these virtual textures to complete terrain rendering. However, the sampling process of RVT is mainly performed on the XY plane, which works well on the horizontal plane, but will cause severe texture stretching when sampling in the Z direction.

[0056] This texture stretching phenomenon is mainly due to the fact that RVT adopts a top-down perspective by default when capturing terrain data. There is a lack of effective correction mechanism for texture sampling on vertical surfaces, which causes the texture coordinates in the Z direction to fail to correctly reflect the real terrain details.

[0057] In order to overcome the above challenges, a new technical solution is urgently needed that can solve the problem of RVT texture stretching in the Z direction without significantly increasing the computational overhead, thereby improving the quality of seamless connection between terrain and model.

[0058] At present, the commonly used methods to solve the texture stretching of RVT in the Z direction are mainly the following:

[0059] 1. Angle elimination method:

[0060] Principle: Based on the viewing angle and the normal direction of the terrain surface, areas that may cause severe texture stretching are eliminated or adjusted. This method calculates the angle between the normal and the line of sight of each terrain fragment. When the angle exceeds a certain threshold, the fragment is eliminated or specially processed.

[0061] Advantages: Simple and easy to implement, and can effectively reduce severe texture stretching.

[0062] Disadvantages: Visual discontinuity: At certain viewing angles, visual discontinuity may occur due to the removal of fragments exceeding the threshold angle. This discontinuity is particularly obvious at the joints of complex terrain or models, affecting the overall visual effect and immersion.

[0063] Computational cost: Each time you render, you need to calculate the normal and view angle of each terrain fragment and decide whether to cull it, which adds additional computational cost. For large terrain or complex scenes, this calculation may significantly affect rendering performance.

[0064] Applicability limitations: Angle culling has limited effectiveness when dealing with completely vertical models, such as tree trunks. When basically all RVT parts are stretched, culling will simply cull it all and cannot solve the effect problem.

[0065] 2. Multi-layer texture mapping:

[0066] Principle: Use multiple layers of texture mapping at different angles to ensure that good texture details can be obtained at different viewing angles. Typical methods include triplanar mapping, which projects the texture onto the XY, XZ, and YZ planes respectively, and blends these projection results according to the normal direction.

[0067] Advantages: It can significantly reduce texture stretching in the Z direction and maintain consistent texture details under multiple viewing angles.

[0068] Disadvantages: Computational complexity: Triplanar mapping requires three texture sampling and blending operations for each fragment, which increases the computational complexity and workload of the shader. This has high performance requirements for real-time rendering and may affect frame rate and overall performance.

[0069] Based on this, this solution provides a terrain rendering method in the game, which calculates the height difference of the object relative to the terrain surface and adjusts the height difference in the normal direction to obtain the height offset value, and then dynamically adjusts the UV coordinates of the RVT sampling based on the height offset value to correct the texture stretching phenomenon during RVT sampling, making the transition effect of the intersection area of ​​the object and the terrain more realistic, thereby improving the rendering effect of the intersection area of ​​the terrain and the object.

[0070] Figure 1 A flowchart of a terrain rendering method in a game provided by an embodiment of the present application; the execution subject of this solution may be a computer device, such as Figure 1 As shown, the method may include:

[0071] S101, obtaining height data of target terrain and original position information of each vertex in the target object.

[0072] The target terrain may refer to the terrain to be rendered, and the target object may refer to the object that intersects with the target terrain. For example, if a tall building stands on the ground, the ground is the target terrain, and the tall building is the target object.

[0073] The height data of the target terrain may refer to the height of a point where the target terrain and the target object meet. The height data of the target terrain may be obtained by identifying a height map of the target terrain.

[0074] The original position information of each vertex in the target object may refer to the absolute position coordinates of each vertex in the world coordinate system.

[0075] S102: Determine height offset information of each vertex in the target object according to the height data of the target terrain, the original position information of each vertex in the target object, and the normal direction information of each vertex.

[0076] The height offset information is used to represent the height offset value of the vertex relative to the terrain surface of the target terrain.

[0077] According to the height data of the target terrain and the original position information of each vertex in the target object, the height difference of each vertex relative to the terrain surface of the target terrain can be calculated first, and then the height difference is adjusted in combination with the normal direction information of each vertex to obtain the height offset information of each vertex in the target object.

[0078] S103: Determine target position information of each vertex according to the height offset information and original position information of each vertex.

[0079] In some embodiments, based on the height offset information of each vertex and the original position information of each vertex, the target position information of each vertex can be calculated respectively, and the target position information can be input to RTV as the new sampling position of each vertex in the target object for texture sampling.

[0080] By calculating the terrain height data of the target terrain and the height offset information of each vertex in the target object in the world coordinate system, the texture sampling coordinates of each vertex in the target object can be dynamically adjusted to correct the texture stretching phenomenon in the Z direction during RTV sampling, so that texture rendering is performed based on the calculated target position information of each vertex in the target object, making the joint between the target terrain and the target object more natural and smooth.

[0081] S104 , rendering and displaying the intersection area of ​​the target terrain and the target object according to the target position information of each vertex.

[0082] Optionally, the target position information of each vertex can be used as input data for RVT sampling, so that when the RVT is running, texture sampling can be performed from the virtual texture of the target terrain according to the target position information of each vertex, and the intersection area of ​​the target terrain and the target object can be rendered and displayed according to the sampling result. The intersection area here also refers to the seam area.

[0083] It is worth noting that the virtual texture of the target terrain can be generated in advance according to the set height map, normal map and other relevant texture information of the target terrain. Then, in the process of real-time rendering based on RVT, RVT can perform texture sampling from the virtual texture in real time to complete the rendering of the intersection area of ​​the target terrain and the target object in real time.

[0084] This solution samples the virtual texture of the target terrain onto the target object so that the texture of the intersection area between the target object and the target terrain can be integrated with the texture of the target terrain itself, thereby making the joint connection between the target terrain and the target object more natural.

[0085] In summary, the terrain rendering method in the game provided by this embodiment includes: obtaining the height data of the target terrain and the original position information of each vertex in the target object; determining the height offset information of each vertex in the target object according to the height data of the target terrain, the original position information of each vertex in the target object and the normal direction information of each vertex; determining the target position information of each vertex according to the height offset information and the original position information of each vertex; rendering and displaying the intersection area of ​​the target terrain and the target object according to the target position information of each vertex. This method calculates the height difference of the object relative to the terrain surface and adjusts the height difference by the normal direction to obtain the height offset information of the terrain height and the object in the world coordinate system, so that according to the height offset information, the target position information of each vertex in the target object can be obtained, and the target position information is used as the sampling position information of the RVT, thereby realizing the dynamic adjustment of the UV coordinates of the RVT sampling based on the height offset information, so as to correct the texture stretching phenomenon during RVT sampling, so that the transition effect of the intersection area between the object and the terrain is more realistic, and the rendering effect of the intersection area between the terrain and the object is improved.

[0086] Figure 2 A flowchart of another terrain rendering method in a game provided by an embodiment of the present application; optionally, in step S102, determining the height offset information of each vertex in the target object according to the height data of the target terrain, the original position information of each vertex in the target object, and the normal direction information of each vertex may include:

[0087] S201 : Determine the height difference of each vertex relative to the terrain surface according to the height data of the target terrain and the original position information of each vertex in the target object.

[0088] The height difference of each vertex in the target object refers to the height difference of each vertex relative to the terrain surface of the target terrain, and each vertex corresponds to a designated point in the target terrain, and the designated point may be a point located on the same vertical line as the vertex.

[0089] For each vertex in the target object, the height difference of each vertex in the target object can be determined according to the original position information of each vertex and the height data of each vertex corresponding to a designated point in the target terrain.

[0090] S202 : Determine the height difference of each vertex in the first plane and the height difference of each vertex in the second plane according to the height difference of each vertex relative to the terrain surface.

[0091] Next, the height difference of each vertex relative to the terrain surface may be decomposed into a first plane and a second plane, where the first plane may be an x-plane and the second plane may be a y-plane.

[0092] Figure 3This is a schematic diagram of a plane division of an object provided in an embodiment of the present application. Figure 3 As shown, the x plane is the first plane, the y plane is the second plane, and the z plane is the third plane.

[0093] Since RVT sampling is done from top to bottom, when the sampled texture is projected to the z plane, it is the same as the sampling method, and there will be no texture stretching, so no additional processing calculation is required. However, when the texture is projected to the x and y planes, it is inconsistent with the sampling method, and texture stretching occurs, so the texture mapping method of the x and y planes needs to be adjusted, and the core of the adjustment is to be implemented based on the height offset information.

[0094] Optionally, the height difference of each vertex relative to the terrain surface can be multiplied by the vector (1, 0) to obtain the height difference of each vertex in the first plane; the height difference of each vertex relative to the terrain surface can be multiplied by the vector (0, 1) to obtain the height difference of each vertex in the second plane.

[0095] S203 , determining height offset information of each vertex on the first plane according to the height difference of each vertex on the first plane, normal direction information of each vertex, and original position information of each vertex.

[0096] Since the height difference of each vertex in the first plane and the height difference of each vertex in the second plane obtained by decomposition are both two-dimensional vectors, and the original position information of the vertex is three-dimensional coordinates, the height difference can also be adjusted by the normal direction information of each vertex to adjust the two-dimensional height difference to three-dimensional height offset information.

[0097] The normal direction information of each vertex is a three-dimensional vector. The height offset information of each vertex in the first plane can be obtained by multiplying the height difference of each vertex in the first plane by the normal direction information of each vertex and adding the original position information of each vertex.

[0098] S204: Determine height offset information of each vertex on the second plane according to the height difference of each vertex on the second plane, normal direction information of each vertex, and original position information of each vertex.

[0099] Similarly, the height offset information of each vertex in the second plane is obtained by multiplying the height difference of each vertex in the second plane by the normal direction information of each vertex and adding the original position information of each vertex.

[0100] Figure 4 A flowchart of another terrain rendering method in a game provided by an embodiment of the present application; Optionally, in step S203, determining the target position information of each vertex according to the height offset information and the original position information of each vertex may include:

[0101] S401, dividing the surface of the target object into multiple planes.

[0102] The multiple planes include at least a first plane and a second plane.

[0103] Based on the generated mask information of the target object on different planes, the surface of the target object can be divided into multiple planes, and the multiple planes at least include the above-mentioned x plane and y plane, and further, may include the z plane. However, this embodiment focuses on processing the x plane and the y plane.

[0104] S402: Determine vertices belonging to the first plane and vertices belonging to the second plane respectively.

[0105] Based on the divided planes, it is possible to determine which vertices on the target object belong to the x-plane and which vertices belong to the y-plane, that is, to determine the vertices contained in the x-plane and the vertices contained in the y-plane.

[0106] S403 , determining target position information of each vertex in the first plane according to original position information of each vertex in the first plane, height offset information of each vertex in the first plane in the first plane, and height offset information of each vertex in the first plane in the second plane.

[0107] Next, the target position information of each vertex can be obtained by interpolating each vertex in the x-plane, and the target position information of each vertex can be obtained by interpolating each vertex in the y-plane.

[0108] Optionally, for each vertex in the x-plane, an interpolation operation can be performed based on the original position information of each vertex and the height offset information of each vertex in the x-plane and the height offset information of each vertex in the y-plane to obtain the target position information of each vertex in the first plane.

[0109] S404: Determine target position information of each vertex in the second plane according to original position information of each vertex in the second plane, height offset information of each vertex in the second plane in the first plane, and height offset information of each vertex in the second plane in the second plane.

[0110] Similarly, for each vertex in the y plane, an interpolation operation can be performed based on the original position information of each vertex and the height offset information of each vertex in the y plane and the height offset information of each vertex in the x plane to obtain the target position information of each vertex in the second plane.

[0111] Figure 5A flowchart of another terrain rendering method in a game provided by an embodiment of the present application; optionally, in step S403, determining the target position information of each vertex in the first plane according to the original position information of each vertex in the first plane, the height offset information of each vertex in the first plane, and the height offset information of each vertex in the first plane in the second plane may include:

[0112] S501 , performing a first interpolation according to original position information of a target vertex in a first plane and height offset information of the target vertex in the first plane to determine an intermediate interpolation result.

[0113] Taking the operation of any target vertex in the x-plane as an example, the height offset information of the target vertex in the x-plane and the original position information of the target vertex may be interpolated to obtain an intermediate interpolation result.

[0114] S502 , performing a second interpolation according to the intermediate interpolation result and the height offset information of the target vertex in the second plane to determine the target position information of the target vertex in the first plane.

[0115] The intermediate interpolation result is then interpolated again with the height offset information of the target vertex in the y plane, and the target position information of any target vertex in the x plane can be obtained.

[0116] If the operation of any target vertex in the y plane is taken as an example, the height offset information of the target vertex in the y plane and the original position information of the target vertex can be interpolated to obtain an intermediate interpolation result, and then the intermediate interpolation result and the height offset information of the target vertex in the x plane are interpolated again to obtain the target position information of any target vertex in the y plane.

[0117] For any vertex in the z plane, the original position information of the vertex can be used as the target position information of the vertex, that is, the position coordinates of the vertex in the z plane do not need to be additionally processed.

[0118] Figure 6 A flowchart of another terrain rendering method in a game provided by an embodiment of the present application; optionally, in step S104, rendering and displaying the intersection area of ​​the target terrain and the target object according to the target position information of each vertex may include:

[0120] In some embodiments, the target position information of each vertex may be used as the sampling position information of each vertex, and the sampling position information of each vertex may be input into the RVT for texture sampling.

[0121] S602: Sample the virtual texture of the target terrain according to the sampling position information of each vertex, and render and display the intersection area of ​​the target terrain and the target object.

[0122] Optionally, when running, the RVT can sample the texture data of each vertex from the virtual texture of the target terrain according to the sampling position information of each vertex, and render and display the intersection area of ​​the target terrain and the target object according to the texture data.

[0123] Figure 7 A flowchart of another terrain rendering method in a game provided by an embodiment of the present application; Optionally, in step S402, respectively determining the vertices belonging to the first plane and the vertices belonging to the second plane may include:

[0124] S701 . According to mask information of the target object, determine each vertex located in a first plane mask of the target object as a vertex belonging to the first plane.

[0125] The mask information of the target object can be generated according to the coordinate information of each vertex in the target object. Through the mask generation technology, the mask of the target object in the x plane, the mask of the y plane and the mask of the z plane can be generated. In other words, the surface of the target object is divided into three planes, the x plane corresponds to the mask of the x plane, the y plane corresponds to the mask of the y plane, and the z plane corresponds to the mask of the z plane.

[0126] Each vertex included in the x-plane mask may be regarded as a vertex belonging to the first plane.

[0127] S702: Determine each vertex located in the second plane mask of the target object as a vertex belonging to the second plane.

[0128] Similarly, each vertex included in the y-plane mask can be regarded as a vertex belonging to the second plane.

[0131] The initial mask information at least includes: initial mask information of a first plane of the target object and initial mask information of a second plane of the target object.

[0132] In some embodiments, the coordinate information of each vertex in different planes can be extracted based on the original position coordinates of each vertex in the target object, so that based on the extracted coordinate information of different planes, the initial mask information of the x plane of the target object and the initial mask information of the y plane of the target object can be generated respectively by using mask generation technology. The mask information is also the data representation of the mask image. Generating the mask information can also be understood as generating the mask image. The mask information is usually composed of a data set, and the data set is composed of 0 or 1 pixel points. Based on the mask information, a corresponding mask image can be generated.

[0133] When the initial mask information of the x-plane and the initial mask information of the y-plane of the target object are known, the initial mask information of the z-plane can be directly calculated through mathematical calculation.

[0144] S901 . Generate smooth seam information corresponding to the first plane according to mask seam range parameters and initial mask information of the first plane.

[0145] The smooth seam information corresponding to the first plane includes: the smooth seam information between the first plane and the second plane and the smooth seam information between the first plane and the third plane.

[0146] Taking the calculation of the x-plane as an example, the SmoothStep function can be used to calculate the smooth seam information corresponding to the x-plane. The formula of the SmoothStep function is as follows:

[0147]

[0148] Among them, min refers to the minimum range parameter mentioned above, max refers to the maximum range parameter mentioned above, and value refers to the initial mask information. When calculating the smooth seam information of the x plane, value takes the initial mask information of the x plane. The value m returned by the function is the smooth seam information of the plane.

[0149] S902 , reversely process the smooth seam information corresponding to the first plane to obtain reversed smooth seam information corresponding to the first plane.

[0150] Assuming that the smooth seam information of the x-plane is SmoothStepx, then the smooth seam information after the inversion of the x-plane can be calculated by (1-SmoothStepx).

[0151] S903 . Determine mask seam information of the first plane according to the smooth seam information corresponding to the first plane and the inverted smooth seam information corresponding to the first plane.

[0152] Next, the mask seam information of the first plane may be calculated according to SmoothStepx*(1-SmoothStepx).

[0154] S1001. Add the processed mask seam information of the first plane to the initial mask information of the first plane to obtain an intermediate result.

[0155] Continuing with the x-plane as an example, the processed mask seam information of the x-plane may be added to the initial mask information of the x-plane to obtain an intermediate result.

[0156] S1002: Process the intermediate result to obtain mask information of the first plane of the target object.

[0157] Optionally, the intermediate result may be rounded off, that is, the intermediate result may be rounded off to an integer to obtain the mask information of the x-plane, which is also the final mask information of the x-plane.

[0158] In one implementable manner, in step S103, the target position information of each vertex is determined based on the height offset information and the original position information of each vertex, and it may also include: determining the target position information of each vertex based on the height offset information of each vertex, the original position information of each vertex and the mask information of each plane.

[0159] Optionally, the height offset information of the vertex in the x-plane may be interpolated with the original position information according to the mask information of the x-plane to obtain an intermediate result, and then the intermediate result may be interpolated with the height offset information in the y-plane according to the mask information of the y-plane to obtain the target position information of the vertex.

[0161] S1101 . Determine the texture position of each vertex in the virtual texture according to the sampling position information of each vertex.

[0162] The virtual texture is the virtual texture of the target terrain.

[0163] Since each vertex in the target object corresponds to a UV coordinate, the position of the texture information to be sampled can be determined from the virtual texture according to the UV coordinate corresponding to each vertex.

[0164] Therefore, according to the sampling position information of each vertex, the texture position corresponding to each vertex can be determined from the virtual texture through the UV coordinates corresponding to the sampling position information.

[0165] S1102: Determine texture information of each vertex according to the texture position corresponding to each vertex.

[0166] The texture information at the texture position corresponding to each vertex is obtained as the texture information of each vertex.

[0167] S1103 . Render and display the intersection area of ​​the target terrain and the target object according to the texture information of each vertex.

[0168] According to the texture information of each vertex, the intersection area of ​​the target object and the target terrain can be rendered and displayed.

[0169] Fig.12 A schematic diagram of a rendering result provided in an embodiment of the present application is shown in FIG. Fig.12 (a) in the figure shows the rendering result that is not processed by this solution. Obviously, there is texture stretching in the intersection area between the object and the terrain in the unprocessed rendering result. Fig.12 (b) in the figure shows the rendering result after being processed by this solution. It can be seen that the texture transition in the intersection area between the object and the terrain is more natural and realistic, and the texture stretching phenomenon is corrected.

[0170] In summary, the terrain rendering method in the game provided by this embodiment includes: obtaining the height data of the target terrain and the original position information of each vertex in the target object; determining the height offset information of each vertex in the target object according to the height data of the target terrain, the original position information of each vertex in the target object and the normal direction information of each vertex; determining the target position information of each vertex according to the height offset information and the original position information of each vertex; rendering and displaying the intersection area of ​​the target terrain and the target object according to the target position information of each vertex. This method calculates the height difference of the object relative to the terrain surface and adjusts the height difference by the normal direction to obtain the height offset information of the terrain height and the object in the world coordinate system, so that according to the height offset information, the target position information of each vertex in the target object can be obtained, and the target position information is used as the sampling position information of the RVT, thereby realizing the dynamic adjustment of the UV coordinates of the RVT sampling based on the height offset information, so as to correct the texture stretching phenomenon during RVT sampling, so that the transition effect of the intersection area between the object and the terrain is more realistic, and the rendering effect of the intersection area between the terrain and the object is improved.

[0171] Secondly, since the texture sampling result can be dynamically adjusted by extracting the height offset information, the present solution can dynamically adapt to the rendering of different terrains and objects and has stronger applicability.

[0172] In addition, the implementation of this solution is relatively simple, will not significantly increase rendering time and performance burden, and the solution operates more efficiently.
