(...) A new, fully revised and up-to-date Primitives Reference is currently undergoing review. I hope to be able to make this public on ldraw.org soon. This will answer both there questions (and more !). Chris (22 years ago, 10-Oct-02, to lugnet.cad.dev, lugnet.cad.dat.parts.primitives)

Hi all, I have a question about the sphere primitives: Does there exists a 1-16sphe.dat? (the half of a 1-8sphe) If not, is it possible that I could make one like this (only wireframe): 1 16 0 0 0 10 0 0 0 1 0 0 0 10 1-4edge.dat 1 16 0 0 0 9.2388 (...)

(...) Most programs that use DAT files as the sources file for a rendered image break all the quads into triangles anyway. Technically, this change would slow down the conversion process (though you would need a *lot* of studs) -Orion (22 years ago, 14-Jul-02, to lugnet.cad.dat.parts.primitives)
