| | | (...) I'm guessing this is a limitation of the accuracy of the l3p -check, so probably ignorable. Does the -dist option affect this test too, or just the coplanar quad test? Maybe there could be another option in l3p to adjust the accuracy of the (...) (20 years ago, 8-Jan-05, to lugnet.cad.dev)

| | | | | (...) I think so too. William, could you please e-mail me the actual coordinates of A, B, etc., and perhaps the whole file. (...) Good question! (...) The colinearity test currently has a hardcoded threshold of 0.01. The colinearity test is carried (...) (20 years ago, 8-Jan-05, to lugnet.cad.dev)

| | | | | | (...) That's a small triangle! Side lengths: 0.0684 0.0671 0.0132 The reason it doesn't show in L3Lab is that you have color coded it in your file! Back in 1998 PovRay would crash if it was given a triangle with collinear vertices and a texture (...) (20 years ago, 14-Jan-05, to lugnet.cad.dev)
