ShaderLab command: Cull

Sets which polygons the GPU should cull, based on the direction that they are facing relative to the camera.

Culling is the process of determining what not to draw. Culling improves rendering efficiency, by not wasting GPU time drawing things that would not be visible in the final image.

By default, the GPU performs back-face culling; this means that it does not draw polygons that face away from the viewer. In general, the more you can reduce the rendering workload, the better; you should therefore change this setting only when necessary.

사용법

This command makes a change to the render state. Use it in a Pass block to set the render state for that Pass, or use it in a SubShader block to set the render state for all Passes in that SubShader.

Shader "Examples/CommandExample"
{
    SubShader
    {
         // The rest of the code that defines the SubShader goes here.

        Pass
        {    
              // Disable culling for this Pass.
              // You would typically do this for special effects, such as transparent objects or double-sided walls.
              Cull Off
            
              // The rest of the code that defines the Pass goes here.
        }
    }
}

This example code demonstrates the syntax for using this command in a SubShader block.

Shader "Examples/CommandExample"
{
    SubShader
    {
         // Disable culling for this SubShader.
         // You would typically do this for special effects, such as transparent objects or double-sided walls.
         Cull Off

         // The rest of the code that defines the SubShader goes here.        

        Pass
        {    
              // The rest of the code that defines the Pass goes here.
        }
    }
}
