spacecut (plural spacecuts)

(computer graphics, demoscene) An animated visual effect in which one polyhedron intersects another, forming an empty space where their volumes overlap.
- 1993, Keith Lau, “More help needed! Spacecuts, etc ...”, in comp.graphics (Usenet):
  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!
