But now have a look at what POV can do... ("with a little help from my fiends" :-) I started 3 1/2 years ago but never finished building the 2556 in LDraw http://news.lugnet.com/cad/?n=971 so I grabbed the Ferrari by Kenneth Storm from http://www.leocad.org/models/old/models.htm and in LeoCAD I exported a DAT file, ks2556.dat Then I ran it through L3P: l3p ks2556 -b15 -f19 -cg11,52,-5 -ca45 and made the POV file available at http://home16.inet.tele.dk/hassing/ks2556.zip Next I asked the remarkably talented people at povray.org what they could do with that scene http://news.povray.org/povray.newusers/26913/ and look what came up...

Fantastic renderings ! Both ! The Brazil 3D-Studio and the POV-Ray. Now the question is: how can we "normal" users (without Silicon graphic equipment ;-) ) make SO NICE renderings ?! For example I'm using ML-Cad, L3PAO, LGEO parts library and (...) (22 years ago, 3-Sep-02, to lugnet.cad.ray)
