(...) Bram Lambrecht gave you the formula. 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)

(...) If an alorithm for this works fast enough, it could have multiple uses: 1) Sort with the parts furthest from the viewpoint first to make instructions as legible as possible and make all parts visible. 2) Sort with the parts closest to the (...) (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. HTH, (...) (23 years ago, 28-Aug-01, to lugnet.cad)

Having just recently searched through all 20,000+ posts in the lugnet.cad archive, it was more than a little frustrating to find that these parts (2997 and 2998) that have been asked for repeatedly always result in people being referred back to (...) (23 years ago, 28-Aug-01, to lugnet.cad)
