The GenerateMipMaps method is a static function within the Sandbox.Graphics class. It is used to generate mipmaps for a given texture. Mipmaps are pre-calculated, optimized sequences of images that accompany a main texture, each of which is a progressively lower resolution representation of the original texture. This method allows for efficient texture sampling and rendering, especially when textures are viewed at a distance or at smaller sizes.
To use the GenerateMipMaps method, you need to provide the following parameters:
texture: The Sandbox.Texture object for which mipmaps are to be generated.downsampleMethod: A Sandbox.Graphics.DownsampleMethod enumeration value that specifies the method to use for downsampling the texture.initialMip: An int specifying the starting mip level from which to begin generating mipmaps.numMips: An int specifying the number of mip levels to generate.Ensure that the texture is properly initialized and that the graphics context is active before calling this method.
// Example of using GenerateMipMaps
Texture myTexture = new Texture("path/to/texture.png");
Graphics.DownsampleMethod method = Graphics.DownsampleMethod.Linear;
int initialMipLevel = 0;
int numberOfMips = 4;
// Generate mipmaps for the texture
Graphics.GenerateMipMaps(myTexture, method, initialMipLevel, numberOfMips);
