For official parts, what I'd *love* to do is to build a separate library of
POV-Ray parts that are made to be compatible with LDraw settings, in terms
of placement, orientation, and coordinate system.  These parts would match
their LDraw counterparts in positioning, but wouldn't have to have anything
in common at the code level.  They could be much higher quality (rounded
edges, true curved surfaces, etc., etc.).  This would allow people to
create models in LDraw, but then use the POV-Ray parts for rendering.

The L3GO parts could be folded in using this method.


Except they increase the size of the parts library.  Disk space may be
cheap, but it's still not free, and many people still use modems to
download.  Bigger files cost them time (and often money, too).


In general, the POV definitions are much smaller than the DAT counterparts,
so the size increase is menimal.  However, perhaps a set of files that could
be downloaded seperately and "overloaded" on top could be the best way to go.

(...) This is a very cool feature, for anyone 'rolling their own'. I'd definitely recommend it for including scanned/bitmap images (like printed tiles), as the POV-Ray versions will be far superior to an BMP2DAT2POV-Ray conversion. For official (...) (24 years ago, 4-Dec-00, to lugnet.cad.ray)
