| | | (...) Well, I added an initial go at Martijn's suggested algorithm to LDView (with some modifications here and there), and the results look extremely promising. Here is a sample: (URL) that this was rendered with Primitive Substitution disabled, so (...) (23 years ago, 20-May-02, to lugnet.cad.dev)

Only calculated when an edge is an exact match with a type 5 line; this requires some extra work to accomplish. Completely ignore the (...) (23 years ago, 20-May-02, to lugnet.cad.dev)

| | | | (...) If you ignore the type 5 control points, what points do you use to generate the cross products? I would think to generate "fair" lengthy vectors you'd have to use the center of gravity point for the adjacent quads or triangles. Otherwise you (...) (23 years ago, 21-May-02, to lugnet.cad.dev)

| | | | (...) I only use the actual (un-normalized) normals of the faces adjacent to the type 5 line. It's a little more complicated, because when a single point has multiple type 5 lines radiating out from it, the surface normal I compute at that point (...)
