"cap holes" algorithm

Hi,

where can I find algorithm to create triangles in the holes
in a 3D-mesh? My main trouble is when a hole is non-planar.

Thanks for any help :)

Why would that be a trouble?  It's a *hole*, after all, so whatever
triangles you put into it, there's no "correct" surface shape you
might represent incorrectly --- since there is no surface whatsoever
inside the hole.

Just choose an arbitrary triplet of consequntial vertices of the hole
boundary polyline, output a triangle with these three vertices, and
dismiss the inner vertex in the triplet.  Repeat until only two
vertices remain. Done.

Does anyone have a problem using PhotoShop 3.  I have alien skin filters
and Kai's Power Tools and yet if I use the spheroid designer in Kai's Power
Tools and then try to add a drop shadow to it using alien skin, PhotoShop
crashes.  Has anyone got a solution to this problem.  It's really bugging
me (pun not intentional).

Yours Pete
