- I'm looking for an algorithm (or better yet, a program) that would
- tessellate/triangulate an arbitrarily-shaped planar surface, possibly with one
- or more arbitrarily-shaped cutouts/holes in it, given only the outline points.
- These points for the external outline will be in one order
- (clockwise/anti-clockwise) and the points representing cutout outlines will be
- in the opposite order. At this point, I'm not really worried about the size of
- these "mosaic" pieces as long as they're either triangular or quadrilateral.
- I've seen this being done in finite-element analyses software. I'd appreciate
- it if anyone who has information on this could give me some ideas. Thanks.
