I'm in the process of creating a lists of polygons from other lists of polygons (triangles in this case). Thing is the function that creates the new list of triangles from the old one, does produce overlapping triangles. What I actually get is a list of lists of vertices and my idea is to discard a triangle if the distance of each of his vertices from the vertices of any other is less than, say, 0.1. Can I use Union and a sametest? What I'm unable to write down is a feasible declaration of this test. Any help would be appreciated Thanks in advance
