The following improvements have been introduced in Boolean Operations algorithm s:
1. UBTree is replaced with EBTree in Boolean operations to be able to add/remove elements into the tree of bounding boxes.
2. Repeated (nested) intersection of sub-shapes is performed with argument vertices whose tolerances increased during the operation.
3. The algorithms of Edge/Edge and Edge/Face intersection have been improved for the cases when the intersection point is located close to the edge boundaries .
4. New procedure has been implemented to ensure forced creation of Edge/Face common blocks in cases when the edge is really close to the face.
5. Post-processing of Face/Face intersection results has been improved.
6. Extension of the planar faces for Plane/Plane intersection is avoided.
7. Builder Face now better classifies potentially internal edges relatively to new faces with filtering by bounding boxes.
Side effect changes:
1. IntTools_ShrunkRange now keeps the length of the valid range of the edge.
2. The method BOPDS_DS::UpdateEdgeTolerance() has been removed as unused (replaced by the BOPAlgo_PaveFiller::UpdateEdgeTolerance()).
