[Algorithms] Res: Res: Polygon from point cloud and other from triangle list?

[Jose M. <jos...@ya...>]

Yes, polygon union!

I should have done more research before posting, so the description of the problem would be more clear.

I have found some libraries that do that, but all that I need is a simple algorithm to compute the union, not a full feature geometry library.

Thanks

this is a completely different problem, this is just a polygon union
function isn't it?

Just because the world is full of people that think just like you,
doesn't mean the other ones can't be right.
