Take the world space coordinates and divides the X and Y coordinates by the Z coordinate. One way this is useful is by using a texture with this projection as the distribution. You can also use it for camera mapping.

Parameters

    • Coordinate space - Coordinate space used by the texture.
      • World space
      • Object space
      • Normal space (IES Lights)
