(...) 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)

(...) If you want to see the medium blue in LDView, just add the following line to C13-73.dat (anywhere outside the IFPOV section): 0 !COLOUR Medium_Blue CODE 13 VALUE #6E99C8 EDGE 0 Tore, is the color 24 line in the file necessary in order to make (...) (18 years ago, 9-Apr-07, to lugnet.cad.ray)

(...) Now that I'm at work, I'm able to look at Microsoft's implementation of fgets for Visual Studio 2005. They do a lock on the file prior to their loop, then call _fgetc_nolock to get each character, instead of fgetc or fread. (That's an (...) (18 years ago, 9-Apr-07, to lugnet.cad, FTX)

(...) Well, it was worth a try. I tried both LDD1.6 and LDD2.0 . Both required a new Linux /lib32 library, libdrm.so.1 . I got that and installed it. LDD1.6 tries to do what looks like some OpenGLL stuff that isn't supported. It *did* manage to (...) (18 years ago, 9-Apr-07, to lugnet.trains, lugnet.cad.ldd)

(...) As long as you only have one character to 'unget' you could probably speed it up by introducing a static char which holds the 'ungetted' char (or null), instead of going through ungetc() -- fgetc(). OTOH, the if-statement to check if there is (...) (18 years ago, 8-Apr-07, to lugnet.cad)

(...) 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)
