Abstract
Apparatus, systems and methods for optimized frustum clipping via cached clip vertices are disclosed. For example, a method is disclosed, the method including generating a clip vertex for a leading edge of a triangle of a triangle strip or fan, indicating that the leading edge is shared with an adjacent triangle of the triangle strip or fan, and in response to the indication, using the clip vertex as a clip vertex of a trailing edge of the adjacent triangle in the triangle strip or fan. Other implementations are disclosed.
