Spacecut

Also, since part of a polygon (facet) of one object might be obscured by that of another intersecting object, I would assume that the standard Z-sort alogrithms^([sic]) would not be enough. Does this mean that I would have to use Z-buffering, or tessellate (sp?) the resultant (possibly nonconvex) polygon into triangles and draw them in Z-order? If not, what is a fast way of doing spacecuts?

Effect 6: Gouraud spacecut - Probably the worst effect in the demo - has been done miles better before!
