In Constructive solid geometry, an Euler boolean operation is a series of modifications to solid modelling which perserves the Euler characteristic in the boundary representation at every stage. One or more of these Euler boolean operations is stored in a change state, so as to only represent models which are physically realizable. Failing to to maintain the Euler characteristic would result in geometric and topological entities often painted by M._C._Escher.
