    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" ?

    Maybe try the Graphics Gems faq?

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