(...) I'm not sure what you mean by "sort first". However, I do what you say, and make the right and up perpendicular, then use the cross product to determine the direction. POV-Ray is only pedantic when the "vista buffer" is enabled (which is true (...) (19 years ago, 6-Dec-05, to lugnet.cad.ray)

(...) POVray worked hard for those images. Shrinking them is telling it that you have no respect for its work. You never know, all future renders might turn out wrong because it is mad. ;) Tim (19 years ago, 6-Dec-05, to lugnet.cad.dev.org.ldraw, FTX)

(...) While I agree with both of you, we should keep in mind that Orion said that this is a postnuke problem.
