As some of you might have seen, I have been doing some programming lately to convert various 3D file formats to DAT format. This resulted in the MAX2DAT converter, which is useful but does not handle primitives, and is limited to the file formats (...) (20 years ago, 5-Mar-05, to lugnet.cad.dev)

PTBrowser enables the user to create multiple views of the LDraw Parts Tracker Parts List. Each view can be filtered to include only parts meeting user-defined criteria and is displayed in a configurable hierarchy. Parts displayed in each view can (...)

(...) more like a whitepaper-with-actual-code rather than source-code-with-comments. Triangle seems to be a 2D utility, I don't remember it handling 3D curved surfaces. But that shouldn't be a problem in this case. Steve (20 years ago, 28-Feb-05, to lugnet.cad.dev)

(...) Your best bet to get a quick result would probably be to look in some 3D graphics libraries for OpenGL and find working code to get a TT glyph out into a mesh model. Exporting a flat mesh model to LDraw format yourself is not very difficult, (...) (20 years ago, 26-Feb-05, to lugnet.cad.dev)

Does anyone know of a utility to convert TT font glyphs to LDraw DATs? I would be interested in looking at writing such a beast, if it hasn't already been done. I'm looking at this to be able to create LDraw representations of custom stickers. And (...) (20 years ago, 26-Feb-05, to lugnet.cad.dev)
