GEOMETRICAL CONSTRAINT SYSTEM DECOMPOSITION: A MULTI-GROUP APPROACH
Pascal Schreck, Pascal Mathis · International Journal of Computational Geometry & Applications · 2006
Since they help to specify the shape of real objects, geometric constraint systems encountered in CAD domain are often invariant by isometries. But other transformation groups can be considered to improve the solving process. More precisely, using different transformation groups leads to a new approach of decomposition which generalizes in some sense the classical approaches. This paper presents a method able to perform such a multi-group decomposition.
