Heya,

Can anyone point me to an algorithm for converting a polyline to a triangle
mesh?  The polyline must be allowed to be highly irregular - concave,
definitely.  Maybe not ... ummm ... fully connected.

I've been doing some googling, but so far I've had surprisingly limited
success.[1]  So I thought I'd ask here. :)  Anyway, back to googling...

I coulda sworn I mentioned this here before.

  http://www-2.cs.cmu.edu/~quake/triangle.html

But I can't find the reference (something about stained glass window
patterns).

Oops, found it.

Just in case I lose it again:  Delaunay, triangle, vectorize, mesh, polyline,
voronoi, and tesselate!  That oughta do it...

(...) Uh. Wow. Yeah, that should do what I need. If it can fill in Lake Superior, it should handle my little de-rasterized figure. I suspect that using Triangle on my little polygon-filling exercise will be like using a firehose to water a flower (...) (20 years ago, 21-Sep-04, to lugnet.cad.dev)
