OCC.Bnd module¶

Supports the Boundings Volumes. A Bounding Volumeis used to bound a shape to optimising algorithms.If a point is outside the Bounding Volume of ashape it is also outside the shape. The contraryis not necessarily true.Various classes are then implemented to describethe usual Bounding volumes. Not all classes areimplemented.in 3D :Box ImplementedBoundSortBox Implementedin 2D :Box2d ImplementedBoundSortBox2d Implemented-Level : Public.All methods of all classes will be public.
