<x-flowed>Hi John,

Here are a few more questions for you - what type of polygons are you 
drawing? Triangles, triangle strips, polygons....?  Is there any chance 
that you are drawing concave polygons? Non-planar polygons? Non-simple 
polygons? The pattern continually changes as you move - what if you 
re-render and stay still (for example, hit the "s" key) - does the image 
change? What if you change the clipping range and re-render without moving, 
does the image change?
