Detailed Description

VSG extension Stores the current logical pixel operation for rendering.

This element stores the current logical pixel operation for rendering.

A Logical Operation is a Per-Sample Processing operation applied between the Fragment's color values and color values in the Framebuffer being rendered to that correspond to that particular fragment color. Logical operations are boolean operations performed on the bit pattern that represents the colors.
