1. The class Bnd_OBB has been created to describe the Oriented Bounding Box. 2. Several key methods have been implemented: Bnd_OBB::IsOut(...), Bnd_OBB::Add(...) and Bnd_OBB::Enlarge(...). 3. Interface of Bnd_Box class has changed. New methods have been created. See Bnd_Box.hxx for detailed information. 4. BRepBndLib and Draw_Box classes have been amended in order to provide correct work with Bnd_OBB class. 5. Interface of "bounding" DRAW-command has been changed. Please see help for detailed information. 6. New DRAW-command "isbbinterf" has been created. Please see help for detailed information. 7. "boundingstr" and "optbounding" DRAW-commands have been eliminated because their function can be made by "bounding" DRAW-command (e.g. see tests/bugs/vis/buc60857 or samples/tcl/snowflake.tcl test cases). 8. Documentation has been updated.
