How can I remove unnecessary triangles from it? Every set of 3 values in the DrawElements array forms a triangle. Each value is an index into the VertexArray list in your Geometry. Go through and find any vertex that falls outside your original boundary and remove it's indicies from the DrawElements. There is a function DelaunayTriangulator::removeInternalTriangles that does the opposite operation. You could probably use that as a template. Glenn
