| | | | | | | (...) You're right; I'm wrong. I'm still having a hard time visualizing it, but your stud example below convinced me that negating the one value in the matrix will indeed flip a 2D primitive like a disk, and this is the expected behavior. In fact, (...) (21 years ago, 3-Jan-04, to lugnet.cad.dev)
