(...) If we want to bulk up the release and clear out a bit more from the tracker, it might be nice to get the Duplo stud primitives certified. Just getting those 4 files certified would get those plus 15 more files into the next release. When the (...) (22 years ago, 18-Apr-02, to lugnet.cad.dev.org.ldraw)

Since "973ps4" (the Han Solo w/ vest torso) is one of the files that is certified and awaiting release, I need to ask: Weren't we going to switch this file's pattern number with "973ps5" (the Darth Vader torso)?... (Ref: "(URL) (22 years ago, 18-Apr-02, to lugnet.cad.dev.org.ldraw)

All the Horse files, and most of the primitives updated with BFC'ness, are now certified! The one primitive not yet certified is p\48\1-4ndis.dat, but it is not the sole hold-up for any files. Over the next few days, I'll be working on getting the (...) (22 years ago, 18-Apr-02, to lugnet.cad.dev.org.ldraw)

(...) Actually, transparent surface should work fine. As long as they are set to write to the Z buffer when drawn, and their outlines are drawn with Z buffer testing enabled, they should work fine. The wireframe parts that aren't supposed to be (...) (22 years ago, 18-Apr-02, to lugnet.cad.dev)

(...) 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)
