Detailed Description

Enables storing of individual overlapped triangles (useful for debug).

Tool class for for detection of overlapping of two BVH primitive sets. 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).

Note that input element sets may correspond to different shapes or to the same shape. In first case, tessellations of two given shapes will be tested for intersection (or overlapping, if tolerance is not zero). In second case, tessellation of single shape will be tested for self- intersections. Please note that algorithm results are approximate and depend greatly on the quality of input tessellation(s).
