Detailed Description

Triangle clipping against planes (view frustum and clip planes).

Clipping ensures that only the visible portion of triangles that cross the view frustum boundaries or user-specified clip planes is drawn. Without clipping, triangles that extend outside the view would produce visual artifacts.
