Coplanar triangles substraction

Hi all,

My first post in this forum.
I’m looking for some refs to perform a substraction between 2 triangles and I dont want to use CSG stuff.
By triangles substraction I mean, given two coplanar triangles A and B, I want to generate a list of triangles resulting from the A - B operations

Thx in advance

Well, it IS csg, only in 2d …
Maybe google on “geometry boolean operations” ?

Well… What I though was called CSG can be found there :

Maybe try the Graphics Gems faq?

This will give you methods for performaing all the necessary operations, using trigonometry and/or linear algebra.


Try GPC…
