| (...) Yeah, the stencil buffer, that's gotta be it. If you've got BFC working then you can use the stencil buffer to count how many times an edge is draw in GL_LINE mode. Edges on back facing triangles won't be drawn, so you'll only count one edge (...) (22 years ago, 18-Apr-02, to lugnet.cad.dev)

| (...) That sounds like glPolygonOffset which would be part of the solution because it allows the edges to look clean. We all use that already. (...) I can see how you might accomplish some of that by manipulating glEdgeFlag when you define your (...) (22 years ago, 18-Apr-02, to lugnet.cad.dev)

| (...) OpenGL has glPolygonOffset, which does what you describe by allowing you to move the polygons further away in the Z direction, where the amount they move can depend on the slope of the polygon in the Z direction. This works great, and I use it (...) (22 years ago, 17-Apr-02, to lugnet.cad.dev)

| (...) The obvious case where it's useful is studs - without these lines, viewing any brick from the standard "oblique" position above & to the side, you would see a circle at the top & bottom of each stud, but no sides, which IMHO would not look (...) (22 years ago, 17-Apr-02, to lugnet.cad.dev)

| (...) Well, I believe that there is something called a 'Z offset' that can be used not to actually move the geometry, but to make sure the lines appear 'on top' of the faces. Before I go more into this I need to back up a bit. I currently use the (...) (22 years ago, 17-Apr-02, to lugnet.cad.dev)
