BRepExtrema_ProximityValueTool Class Reference

Tool class for computation of the proximity value from one BVH primitive set to another, solving max(min) problem. Handles only edge/edge or face/face cases. This tool is not intended to be used independently, and is integrated in other classes, implementing algorithms based on shape tessellation (BRepExtrema_ShapeProximity and BRepExtrema_SelfIntersection).

Detailed Description

Tool class for computation of the proximity value from one BVH primitive set to another, solving max(min) problem. Handles only edge/edge or face/face cases. This tool is not intended to be used independently, and is integrated in other classes, implementing algorithms based on shape tessellation (BRepExtrema_ShapeProximity and BRepExtrema_SelfIntersection).

Please note that algorithm results are approximate and depend greatly on the quality of input tessellation(s).
