View Full Version : is there a way to determine the perimeter of a triangulated planar structure

11-03-2008, 12:54 PM

I have a planar object made up of about 20 triangulated polygons;

I would like to write a script that would go through the object, one triangle at a time and in no specific order, and determine what vertices form the boundary of the object;

it is fair to say that all triangles have normals in the same direction;

the final list of vertices will need to maintain the same cw/ccw orientation as any and all of the triangles;

any thoughts;
