Some embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Considering the situation that the existing game pictures are not natural in connection at the place where the vegetation disappears, in the reality nature, when the place where one piece of vegetation is covered is farther and farther away from the place where the vegetation is covered, the details of the vegetation, such as the structure of the plants, the venation of the leaves and the like, can not be seen slowly, and only one piece of color is covered on the terrain finally, so that the invention provides a rendering method, a rendering device and electronic equipment of the game pictures, which can effectively improve the vegetation and terrain connection effect and improve the sense of reality of the game pictures.
For easy understanding, first, a detailed description will be given of a method for rendering a game screen according to an embodiment of the present invention, referring to a flowchart of a method for rendering a game screen shown in fig. 1, the method mainly includes steps S102 to S108 as follows:
step S102: and extracting the colors of vegetation textures in the initial game picture.
In one embodiment, the initial game frame may include a game scene that has been rendered, but because some game scenes are far away from the camera (i.e. where vegetation disappears) and there is an unnatural connection, it is necessary to render the frame far away from the camera to obtain a natural connection and real game frame, first extracting the color of the plant leaves in the initial vegetation texture in the initial game frame, and downsampling the color of the plant leaves in the extracted vegetation texture, such as downsampling the resolution by Box Filter by half each time, until a first rendering color (also called the color of the texture) with a resolution of 1×1 is obtained, so as to provide the initial rendering color for the remote game frame rendering.
Step S104: mapping the colors of the vegetation textures to a preset background texture to obtain a target texture.
In one embodiment, the preset background texture may be a texture set according to the size of the vegetation texture, where the texture includes three channels of RGB, first, initializing color data to 0, that is, obtaining the background texture, where the unit of the background texture is a pixel, the size may be set to w, performing color processing and blurring on the color of the extracted vegetation texture, and obtaining a vegetation effect similar to a position far away in reality, and mapping the processed vegetation texture on the preset background texture to obtain a target texture based on the color of the vegetation texture to be filled according to the position and the range of the vegetation.
Step S106: and determining the target rendering intensity based on the preset attenuation starting distance and the preset rendering distance.
In one embodiment, the preset attenuation starting distance may be a distance from the camera where the vegetation begins to disappear in the initial game screen, the preset rendering distance may be a farthest distance that can be displayed in the screen, and since the effect of rendering from the preset attenuation starting distance to the preset rendering distance should be a gradually disappearing vegetation color effect, the target rendering intensity needs to be set for rendering, the target rendering intensity is selected according to the distance from the attenuation starting distance to the farther distance when the target rendering intensity is rendered according to the colors of all vegetation textures within the preset attenuation starting distance.
Step S108: interpolation is carried out in the initial game picture based on the target texture and the target rendering strength, and the final game picture is rendered.
The obtained target texture and target rendering intensity need to be rendered between a preset attenuation distance and a preset rendering distance in an interpolation mode, so that a realistic effect of vegetation connection in a game picture is achieved.
The invention provides a method for rendering a game picture, which comprises the steps of firstly extracting the colors of vegetation textures in an initial game picture, mapping the colors of the vegetation textures onto a preset background texture to obtain a target texture, determining target rendering strength based on a preset attenuation starting distance and a preset rendering distance, interpolating in the initial game picture based on the target texture and the target rendering strength, and rendering to obtain a final game picture. The vegetation color of the initial game picture is extracted, the extracted vegetation texture is mapped to obtain target texture, interpolation is carried out between the preset attenuation starting distance and the preset rendering distance according to the target rendering intensity through the obtained target texture, and the rendered final game picture is obtained, so that the vegetation effect can still be seen at a distance far from the camera (namely, the distance between the preset attenuation starting distance and the preset rendering distance), the vegetation and the topography have a vivid linking effect, and the reality of the game picture is improved. Therefore, the embodiment of the invention can effectively improve the vegetation and terrain engagement effect and improve the sense of reality of the game picture.
In one embodiment, the game scene may be divided into small squares of a fixed size, the vegetation data is organized in units of a square and saved in a file, and a piece of vegetation data represents vegetation covering a range of terrain. In order to facilitate understanding the above step S104, the present invention provides a specific embodiment for mapping the color of a vegetation texture onto a preset background texture to obtain a target texture, which mainly includes steps 1 to 3 as follows:
step 1, determining a second rendering color of each plant in a preset background texture based on the first rendering color and a preset vegetation vertex color. The plant is at least one plant; the preset vegetation apex color is typically drawn by an artist at the time of editing, such as by marking the first rendered color as C t The color of the top of the vegetation is marked as C v The color of each plant in the background texture (i.e., the second rendered color) may be C r ＝C v ×C t 。
And 2, determining the rendering position of each plant in a preset background texture. In practical application, vegetation in a game picture is obtained by a plurality of plants or clusters of plants, and in order to render a real effect, the colors of each plant or each cluster of plants are different, so that after the colors required by rendering each plant are determined, the rendering position of each plant is calculated, and the real rendering effect is displayed.
And 3, filling the second rendering color of each plant into the corresponding rendering position to obtain a target texture, wherein the result schematic diagram of one target texture is shown in fig. 2.
In addition, since the calculated texture has a relatively hard border at the edge of the vegetation filled with the color, in order to obtain a smooth and natural effect, a preset blurring operation needs to be performed on the target texture, in this embodiment, the blurring operation may be performed on the target texture through, for example, gaussian blurring, and the target texture after gaussian blurring is referred to as a result schematic diagram of another target texture as shown in fig. 3.
The step of determining the rendering position of each plant in the preset background texture may further include the following steps 2.1 to 2.4:
step 2.1, acquiring an axis alignment bounding box of the vegetation template, and determining a projection radius r based on a maximum coordinate max (x, z) and a minimum coordinate min (x, z) of the axis alignment bounding box projected to a horizontal plane, wherein the projection radius r can be expressed by a formulaThe representation is performed.
And 2.2, acquiring a first rendering position of each plant in the target texture. Since the position of vegetation is a local coordinate value relative to the block where it needs to be converted to pixel coordinates on the target texture, for example, it can be calculated using the following formula, where h is the size of the vegetation texture and w is the size of the background texture, (t x ,t y ) I.e. pixel coordinates in the target texture, where floor is a rounding down operation.
Step 2.3, determining a rendering range of each plant in the target texture based on the projection radius and the scaling factor, e.g. the rendering range may apply a formulaA determination is made, where s is a scaling factor.
Step 2.4, determining a target rendering position of each plant in the preset background texture, namely a base, based on the first rendering position and the rendering rangeIn the pixel coordinates (t x ,t y ) And rendering radius r v And determining a target rendering position of each plant in a preset background texture.
In one embodiment, after obtaining the target texture of the vegetation, it is required to apply the target texture as the vertex color of the terrain to the ground (i.e. the game picture) of the game scene, the real vegetation is rendered at a position closer to the camera, and the effect of the target texture is only started to be displayed at a position where the vegetation disappears at a farther position, so that the target texture is required to be displayed according to a preset attenuation starting distance l f And a preset rendering distance l r Determining the rendering intensity, wherein the preset attenuation starting distance l f And a preset rendering distance l r Referring to fig. 4, a specific embodiment of determining the target rendering intensity based on the preset attenuation starting distance and the preset rendering distance includes the following steps:
step A, determining the distance between the rendering position of the final game picture and the camera as a rendering distance l;
step B, based on the rendering distance l and a preset attenuation starting distance l f And a preset rendering distance l r According to the formulaA target rendering intensity f is determined.
In one embodiment, firstly, it is determined whether the terrain has vegetation coverage, if yes, the coverage coefficient is set to 1, otherwise, the coverage coefficient is set to 0, which aims to promote the reality of the game scene, and the vegetation is not rendered on the part which is not covered by the vegetation, and the steps of interpolating in the initial game picture based on the target texture and the target rendering strength and rendering to obtain the final game picture include the following steps (1) to (3):
step (1), obtaining an initial game picture at a preset attenuation starting distance l f And a preset rendering distance l r Terrain apex color in between. In one embodiment, since different terrain vertex colors are set in different seasons in order to achieve a realistic effect of the game screen, such as green in summer and yellow in autumn in the game scene, a more realistic effect of the game screen is obtained according to the different terrain vertex colors.
Step (2), interpolating according to a preset interpolation operation according to the target texture, the terrain vertex color, the target rendering intensity f and the coverage coefficient to obtain the vertex color of vegetation rendering, wherein the preset interpolation operation can adopt a formula of c=lerp (C t ,C e F×c), wherein C t Is the peak color of the terrain, C e And C is the coverage coefficient, and C is the vertex color of vegetation rendering.
And (3) rendering based on the vertex colors of vegetation rendering to obtain a final game picture. And obtaining the vertex color C of vegetation rendering through the interpolation operation, and filling the vertex color corresponding to each rendering position to obtain a final game picture.
