The GrabDepthTexture method in the Sandbox.Graphics class is a static method used to create a depth texture render target. This method is useful for capturing depth information from a scene, which can be used for various rendering techniques such as shadow mapping or post-processing effects.
To use the GrabDepthTexture method, you need to provide the following parameters:
targetName (string): The name of the render target. This is used to identify the render target within the graphics system.renderAttributes (RenderAttributes): A set of attributes that define how the rendering should be performed. This includes settings like resolution, format, and other rendering options.withMips (bool): A boolean value indicating whether mipmaps should be generated for the texture. Mipmaps can improve rendering performance and quality when textures are viewed at smaller sizes.// Example of using GrabDepthTexture
string targetName = "DepthTexture";
RenderAttributes renderAttributes = new RenderAttributes
{
Width = 1024,
Height = 1024,
Format = RenderFormat.Depth32
};
bool withMips = false;
RenderTarget depthTexture = Graphics.GrabDepthTexture(targetName, renderAttributes, withMips);
// Use the depthTexture for rendering operations
