   Jason S. Mantor wrote... (...) The "row 0 all zeroes" warning relates to the "Singular Matrix" problem. Because PovRay is a ray tracer, it needs to calculate transformations backwards and therefore it calculates inverse matrices. If a matrix is (...) (23 years ago, 7-Dec-01, to lugnet.cad)

     Hello (...) Yep . right.. sometimes. ;).. Especially when it is a more complicated part with subpart you get rarely a response. And even in the Lugnet parts tracker people sometimes seem to be scared of subparts ;). Greetings Carsten (23 years ago, 7-Dec-01, to lugnet.cad)

     (...) That would make it easier. But I don't think the server can control the file location during download -- it's up to the browser (and the user). Steve (23 years ago, 10-Dec-01, to lugnet.cad)
