8.11 Manipulating Solids

Manipulations on primitives are performed on a routine basis in solid modeling. Set operations in
constructive solid geometry cannot be performed without transformations, that is, re-positioning or
scaling of the primitives. Further, determining intersection, union or difference involves computing
