Transform, Clipping and Lighting (TCL)

TCL is a common name for three operations:

  • transformation (moving and rotating objects in a scene)
  • clipping (removing non-visible objects)
  • lighting (applying light effects on objects) Most modern graphics cards are able to perform TCL internally with the card's chip - this allows greater speed in all applications, the main system processor(s) doesn't have to do additional work with graphics.

TCL allows far more complex scenes to be calculated in very short time.
