Detailed Description

Sort shapes by their centers of mass, using formula X*999 + Y*99 + Z*0.9.

Algorithm is copied from GEOM module, which uses nexplode Draw command from OCCT. Used for getting index of sub0shape in WeakNaming algorithm.

Member Enumeration Documentation

ShapeOrder

enum GeomAlgoAPI_NExplode::ShapeOrder

Different orders of shape explosion.

Enumerator
ORDER_BY_HASH_VALUE	kept for compatibility
ORDER_BY_MIDDLE_POINT	modern approach comparing middle points of shapes
