Hello,

could someone give me the mathematics needed to calculate the vertex 
normals needed for the smooth_triangle primitive? i need to convert a "
standard" triangle to a smooth one!

thank you
ric

PS: the release of a DXF to POV converter is near, the source already 
quite works for my internal use win non-smoothed triangles. As soon as 
my web-site server comes back I will put it online!
