| | | | | (...) Well I am sort of doing that right now, although not in perl. I chose to use my company's product, sort of as a learning exercise. If someone has perl code that recognises the various line types that would be spiffy. If you have the formula (...) (23 years ago, 28-Aug-01, to lugnet.cad)

| | | | | | | (...) If the viewpoint is at location (a,b,c) and the part is at (x,y,z), then the distance between them is: ((a-x)^2 + (b-y)^2 + (c-z)^2)^0.5 Since all you want to do is sort, there's no need to take the square root after summing the squares.

Depending on what you want to do and what kind of viewing transformation (if any) you are using, the euclidian distance _may_ be the wrong kind of measure to use. But it is probably an ok approximation... (...) (23 years ago, 28-Aug-01, to lugnet.cad)
