(...) <snip> First, this is a nifty idea. Objectifying this is long overdue. But I was struck wondering, is this trying to objectify the current dat format as it is, or an ideal one as we would like to see it be... Also, are you a fan of the MVC (...) (23 years ago, 10-Feb-02, to lugnet.cad.dev)

(...) IIRC (and I wish I could find the reference) the LDraw spec does support this. It depends on the order of the points in the polygon; e.g. clockwise points out, counterclockwise points in. Or something like that. But last I heard of this, there (...) (23 years ago, 10-Feb-02, to lugnet.cad.dev)

(...) I'll have a better answer for this when I port my Java implementation to Perl. But yah, I guess "comprehensive" and "generic" don't quite mix well. I want comprehensive, in that this library could be used for many different methods of (...) (23 years ago, 10-Feb-02, to lugnet.cad.dev)

I like this. I don't think I can contribute that much. I would like to though. I have been working in Java with my animation program ((URL) and I can contribute a class for LineType1. Most useful is a rotation function that I would like to think is (...) (23 years ago, 10-Feb-02, to lugnet.cad.dev)

How about an LDraw DAT model reducer - something that hacks out the insides and leaves nothing but a hollow shell? This way you could port it to platforms that can't handle so many polygons, and also render in realtime. It would kind of be like (...) (23 years ago, 10-Feb-02, to lugnet.cad.dev)
