[comp.sys.sgi] Clipping Problem

mkibler@yoda.eecs.wsu.edu (Michael K. Kibler) (06/05/91)

Is there a known problem with Clipping and Smooth shading on the
IRIS 4D/60T systems? IRIS 3.3.3

It appears that when a polygon point is clipped to one of the
planes in the perspective viewing pyramid, it loses the color
information for the point and does a constant shade of the polygon.
The same type of thing happens when passing normals instead of
colors for each point.

Is there anything that can be done to solve this? Short of performing
the clipping myself.

thanks in advance.
