(...) Yes, it did the trick! I just pasted "SET LDRAWDIR=F:\LDraw" into the batch file and L3P went nicely back to work. Now I have to figure out how to remind Windows please to use its enviroment variables... Thanks again! /Tore (18 years ago, 22-Apr-07, to lugnet.cad.ray)

(...) Sometimes Windows seems to have a hard time remembering environment variables in DOS boxes (I'm sure there's some long, complicated and stupid system to it). Maybe add something to set them to the batch files and see if it works. Tim (18 years ago, 22-Apr-07, to lugnet.cad.ray)

I have used L3P for years, and suddely it went on strike. AutoExec.bat still contains: SET LDRAWDIR=F:\LDraw And the SET command still outputs: LDRAWDIR=F:\LDraw And C:\Windows\ldraw.ini still contains: BaseDirectory=f:\LDraw But running the .bat (...) (18 years ago, 22-Apr-07, to lugnet.cad.ray)

(...) I thought it was, but in this case it wasn't. The color 24 line can be skipped. And the double pigment declaration was just a pure mistake; one definition is of course sufficient. :) /Tore (18 years ago, 9-Apr-07, to lugnet.cad.ray)

(...) Good to know. Thanks! (...) I kind of recall that. In some cases, I've seen that L3P ignores an LDraw file with just Type 0 lines. I haven't checked if the IFPOV code makes it not ignore C13-73.dat, but I just did it in a routine manner. /Tore (18 years ago, 9-Apr-07, to lugnet.cad.ray)

(...) Just take the transpose of the 3x3 world rotation matrix and it should work as the inverse. Transpose means swap diagonals M[1,2] <=> M[2,1] etc. If this doesn't work I've misunderstood you. Tim (18 years ago, 7-Apr-07, to lugnet.cad.ray, lugnet.cad)

(...) I just realised something... do you want a general inverse or a specific inverse? Some inversions are simple eg. a pure rotation can be inverted by taking its transpose and reflections are their own inverses. Tim (18 years ago, 7-Apr-07, to lugnet.cad.ray, lugnet.cad)
