Abstract
Description
Technical Field
[0001] This disclosure relates to the field of game rendering technology, and more specifically, to a method for rendering terrain in a game, a device for rendering terrain in a game, an electronic device, and a computer-readable medium. Background Technology
[0002] In games, terrain transformation primarily involves altering the appearance of the terrain in accordance with weather changes, which can greatly enhance the game's immersion. Currently, to change the appearance of the terrain based on weather, it is often necessary to traverse all objects in the scene, generate a target terrain material for each object, and finally replace the original material with the target material.
[0003] From a game performance perspective, the above solution requires generating a static material for each object when changing the terrain, which is very performance-intensive. If there are many objects, stuttering may occur. Furthermore, the solution needs to iterate through all objects to determine which need to be changed and which don't, making the process cumbersome. In terms of game presentation, directly replacing the original material with the target material results in a sudden change in terrain, significantly impacting the game's realism.
[0004] Therefore, there is an urgent need in this field for a terrain rendering method that can achieve transition effects between different terrain representations and reduce the performance overhead of the game.

[0046] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

In other instances, well-known technical solutions are not shown or described in detail to avoid obscuring various aspects of this disclosure.
[0047] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.
[0048] In the game, changes in terrain mainly involve changes in terrain materials. This means that changes in the external environment in the game can be reflected in the terrain materials through code and other means, allowing the terrain to transition from one material to another.
[0049] This example implementation first provides a method for rendering terrain in a game. (See references) Figure 1 As shown, the terrain rendering method in the above game may include the following steps:
[0050] Step S110. Obtain the world coordinates of each rendering point in the game, and obtain the corresponding texture map coordinates based on the world coordinates of the rendering points.
[0051] Step S120. Sample the first terrain material map and the second terrain material map respectively using texture map coordinates to obtain the first terrain material attributes and the second terrain material attributes.
[0052] Step S130. Obtain multiple different grayscale sampling coordinates based on the world coordinates of the rendering point, and sample the sample grayscale image multiple times using the grayscale sampling coordinates to obtain multiple grayscale image channel sampling values.
[0053] Step S140. Obtain the terrain transition factor corresponding to the rendering point based on the sampling values of multiple grayscale channels, and determine the proportion parameter between the first terrain material and the second terrain material based on the terrain transition factor and the proportion adjustment parameter.
[0054] Step S150. Obtain the blended terrain material attribute based on the first terrain material attribute, the second terrain material attribute, and the proportion parameter, and render the terrain in the game based on the blended terrain material attribute corresponding to each rendering point.
[0055] In the game terrain rendering method of the exemplary implementation of this disclosure, the first terrain material map and the second terrain material map are sampled respectively by the texture map coordinates of the rendering point to obtain the first terrain material attribute and the second terrain material attribute. The grayscale image is sampled multiple times by the grayscale sampling coordinates of the rendering point to obtain multiple grayscale image channel sampling values. Then, the terrain transition factor corresponding to the rendering point is obtained according to the multiple grayscale image channel sampling values. The proportion parameter between the first terrain material and the second terrain material is determined according to the terrain transition factor and the proportion adjustment parameter. Finally, the blended terrain material attribute is obtained according to the first terrain material attribute, the second terrain material attribute and the proportion parameter. The terrain in the game is rendered according to the blended terrain material attribute corresponding to each rendering point. The game terrain rendering method in the exemplary embodiments of this disclosure, on the one hand, by writing multiple terrain representations into the same terrain material and using proportion adjustment parameters to adjust the proportion of different terrain materials, can achieve a natural transition effect between different terrain representations. It can change the terrain representation in real time according to weather changes in the game, solve the problem of abrupt changes in terrain materials, and achieve a real-time gradient effect. On the other hand, when changing the terrain material, it is not necessary to traverse the objects in the scene, generate static materials for the objects, or modify each terrain component separately. It is only necessary to modify the proportion adjustment parameters according to the requirements, which solves the problems of high performance overhead and low operation efficiency.
[0056] Below, in conjunction with Figures 2 to 5 The steps described above in this example implementation will be explained in more detail.
[0057] In step S110, the world coordinates of each rendering point in the game are obtained, and the corresponding texture map coordinates are obtained based on the world coordinates of the rendering points.
[0058] In this example implementation, the world coordinates of the rendering point refer to the coordinates of the rendering point on the X, Y, Z axes of the world coordinate system. The corresponding texture map coordinates can be obtained from the world coordinates of the rendering point. The texture map coordinates are the UV coordinates used to sample the terrain material map.
[0059] In this example implementation, the two-dimensional vector corresponding to the world coordinates can be obtained based on the values of the red and green channels of the world coordinates of the rendering point. Then, the texture map coordinates corresponding to the world coordinates can be obtained by multiplying the two-dimensional vector with the coordinate tuning constant.
[0060] Convert the world coordinates of the current rendering point to meters, then take the R channel (red channel) and G channel (green channel) of the converted world coordinates to form a two-dimensional vector, denoted as WPUV. Multiply the two-dimensional vector WPUV by a manually configured constant (which can be obtained through debugging) to obtain the texture map coordinates corresponding to the world coordinates of the rendering point, denoted as TextureUV.
[0061] In step S120, the first terrain material map and the second terrain material map are sampled by texture map coordinates to obtain the first terrain material attributes and the second terrain material attributes.
[0062] In this example implementation, the terrain texture map may include color maps, normal maps, and roughness maps corresponding to the terrain material. For example... Figure 2 As shown, the first and second terrain textures are sampled using texture map coordinates to obtain the first and second terrain texture attributes. This process can include the following steps:
[0063] Step S210. Sample the color map, normal map, and roughness map of the first and second terrain materials respectively using texture map coordinates to obtain the color parameters, normal parameters, and roughness parameters of the first and second terrain materials.
[0064] The color map, normal map, and roughness map of the first terrain material are sampled using TextureUV coordinates to obtain the color parameter BaseColor1, normal parameter Normal1, and roughness parameter Roughness1 of the first terrain material. Simultaneously, the color map, normal map, and roughness map of the second terrain material are sampled using TextureUV coordinates to obtain the color parameter BaseColor2, normal parameter Normal2, and roughness parameter Roughness2 of the first terrain material.
[0065] Step S220. Integrate the color parameters, normal parameters, and roughness parameters of the first and second terrain materials respectively through the material property establishment function to obtain the first and second terrain material properties.
[0066] The color parameter BaseColor1, normal parameter Normal1, and roughness parameter Roughness1 of the first terrain material are integrated and calculated using the MakeMaterialAttributes function (material attribute creation function) to obtain the first terrain material attribute, denoted as LandA. Here, the terrain material attribute is the attribute set corresponding to the terrain material. Simultaneously, the color parameter BaseColor1, normal parameter Normal1, and roughness parameter Roughness1 of the second terrain material are also integrated and calculated using the MakeMaterialAttributes function to obtain the second terrain material attribute, denoted as LandB.
[0067] In step S130, multiple different grayscale sampling coordinates are obtained based on the world coordinates of the rendering point, and the sample grayscale image is sampled multiple times using the grayscale sampling coordinates to obtain multiple grayscale image channel sampling values.
[0068] In this example implementation, grayscale sampling coordinates are UV coordinates used to sample the grayscale image. By adjusting parameters based on the two-dimensional vector corresponding to the world coordinates of the rendering point and multiple sets of different coordinate offsets, multiple different grayscale sampling coordinates can be obtained.
[0069] Multiplying the 2D vector WPUV corresponding to the world coordinates by a pre-configured parameter S1, and then adding an offset SUV1, yields a grayscale sampling coordinate, expressed by the following formula:
[0070] SampleUV1 = WPUV * S1 + SUV1
[0071] Where S1 is a manually configured constant, SUV1 is a manually configured two-dimensional vector, and SampleUV1 is the UV value required for sampling.
[0072] For multiple sets of different parameters S2, SUV2 and S3, SUV3, grayscale sampling coordinates SampleUV2 and SampleUV3 with different offsets can be calculated.
[0073] In this example implementation, multiple grayscale channel sampling values can be obtained by sampling the red channel of the sample grayscale image multiple times using grayscale sampling coordinates.
[0074] like Figure 3 The diagram shows a sample grayscale image according to a specific embodiment of this disclosure. By sampling the R channel of the sample grayscale image using grayscale sampling coordinates SampleUV1, SampleUV2, and SampleUV3, the corresponding grayscale image channel sampling values R1, R2, and R3 can be obtained. The grayscale image channel sampling values range from 0 to 1.
[0075] In step S140, the terrain transition factor corresponding to the rendering point is obtained based on the sampling values of multiple grayscale channels, and the proportion parameter between the first terrain material and the second terrain material is determined based on the terrain transition factor and the proportion adjustment parameter.
[0076] In this example implementation, the sampled values of multiple grayscale image channels can be weighted and averaged according to preset weight parameters to obtain the terrain transition factor corresponding to the rendering point.
[0077] By multiplying the sampled values R1, R2, and R3 of the grayscale image channels by different weight parameters and then performing a weighted average, the terrain transition factor corresponding to the rendered point can be obtained. The specific formula is as follows:
[0078] TransitionFactor=(I1*R1+I2*R2+I3*R3) / (I1+I2+I3)
[0079] Among them, I1, I2 and I3 are all manually configured constants.
[0080] In this example implementation, the sample grayscale image is sampled multiple times using world coordinates with different offsets, and the sampled values are weighted and averaged to obtain a terrain transition factor with very low redundancy. This allows the two terrain materials to be irregularly blended, resulting in a more natural terrain transition.
[0081] In this example implementation, a material parameter set, denoted as MPC (Material Parameter Collection), can be created. The material parameter set MPC contains a percentage adjustment parameter P. By changing the variables of the material parameter set, all associated materials can be adjusted synchronously.
[0082] The formula for calculating the ratio parameter Alpha between the first and second landform materials is as follows:
[0083] Alpha=Power(Clamp((TransitionFactor-(1-P)) / S3),S4)
[0084] S3 and S4 are manually configured parameters. Clamp is a commonly used rendering function that can restrict a value to between 0 and 1. Power is also a commonly used rendering function; Power(a,b) is equivalent to a^b.
[0085] In step S150, the blended terrain material attributes are obtained based on the first terrain material attributes, the second terrain material attributes, and the proportion parameters, and the terrain in the game is rendered based on the blended terrain material attributes corresponding to each rendering point.
[0086] In this example implementation, the first and second landform material attributes are fused according to the proportion parameter using a material fusion function to obtain the fused landform material attributes.
[0087] The material properties of the blended terrain material that transitions between two terrain materials can be calculated using the following formula:
[0088] LandMaterial=BlendMaterialAttributes(LandA,LandB,Alpha)
[0089] The `BlendMaterialAttributes(A,B,Alpha)` function is used to blend two terrain materials. The `BlendMaterialAttribute` function calculates the blending of two terrain materials. The `Alpha` parameter controls the transition ratio between the two materials; the closer `Alpha` is to 1, the closer the blended material is to `B`, and the closer `Alpha` is to 0, the closer the blended material is to `A`. `LandMaterial` represents the final material representation of the terrain.
[0090] Figure 4 and Figure 5 The illustration shows two terrain transition effect diagrams obtained by a terrain rendering method according to a specific embodiment of this disclosure. During game runtime, by reading the material parameter set MPC and then modifying the P value in real time through code according to weather changes, such as from cloudy to sunny, the transition gradient effect of all relevant terrain materials can be achieved.
[0091] It should be noted that although the steps of the method in this disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or a step may be broken down into multiple steps.
