#8880 TIRE -> Part Number (2997) #8880 WHEEL -> Part Number (2998) Note: These Numbers were taken from the parts, no guessing, they are easilly visible. You can get them from here: Low poly version: (URL) High poly version: (URL) Should I post them (...) (24 years ago, 20-Jun-00, to lugnet.cad.dev)

:-) Much better ... the compution of the determinant of a matrix was wrong ... this explains also some strange effects with bfc ... Thanks anyway! Michael (...) (24 years ago, 20-Jun-00, to lugnet.cad.dev)

AFAIK the only pieces still missing from the 8880 are the wheels and tyres, the gear stick and shift plate and the stickers and decorated elements. If you have finished these parts and are looking for something else to do, dont bother with the 8448 (...) (24 years ago, 20-Jun-00, to lugnet.cad.dev)

(...) Ok I got it partly somehow running, but currently I'm fighting with matrixes which do not have an inversion-matrix, I got to algorythms on how to get the inversion-matrix and in some rare cases they return different values, and tell me that (...) (24 years ago, 19-Jun-00, to lugnet.cad.dev)

(...) What do you mean by "translated into model space" ? Back from World coordinates? By applying inv(VM)? How can you find a z value for the screen point. There are many possible values. (How do you go from 2D to 3D?) Assuming that you could find (...) (24 years ago, 19-Jun-00, to lugnet.cad.dev)
