If so, this should prove that all the lines are defined in the (...) (25 years ago, 30-May-99, to lugnet.cad.dev)

I'm viewing these in ldlite, though I believe I've seen this before in ldraw and ledit.. I'll take another look though just to be (...) (25 years ago, 30-May-99, to lugnet.cad.dev)

The problem is the primitive stud*.dat files are specifying two different colors for the same voxel (3D pixel)--the voxels are the edges are being filled with both the edge color and the surface color. So the renderer has to 'decide' which (...) (25 years ago, 1-Jun-99, to lugnet.cad.dev)

| | | | (...) You don't need to change anything in the LDraw language, you can use something called "Polygon Offset" (those who have used OpenGL will know what I mean), it moves the lines a little bit to the front when checking the Z-buffer.

And it is the following lines near the top of stub.c: // replace pixels within tolerance to avoid rounding problems #define Z_LINE_TOLERANCE 2 // move lines closer to viewer before drawing to avoid (...)
