Abstract
A number of recent papers have argued that invariantsdo not exist for three dimensional point sets in generalposition [3, 4, 13]. This has often been misinterpretedto mean that invariants cannot be computed for anythree dimensional structure. This paper proves by examplethat although the general statement is true, invariantsdo exist for structured three dimensional pointsets.Projective invariants are derived for two classes ofobject: the first is for points that lie on the vertices of...Keywords
