| Summary | 0006503: Incorrect calculation of bounding box for infinite surfaces | ||||
| Description | Run following commands: plane pl 0 0 0 0 0 1 mkface f pl bounding f It gives an infinite bounding box while infinite directions only X and Y, and the box must be thin in Z direction. The same problem occurs with other infinite surfaces. E.g., bounding box of a surface of extrusion must have infinite only one direction if the extrusion direction coincides with one of main axes (X, Y or Z), and two infinite directions if the extrusion direction has a slope but lies in one of planes XOY, YOZ or ZOX. The problem code is in the function BndLib_AddSurface::Add, where box is assigned an infinite value (SetWhole) if one of first/last U/V parameter is infinite. Note that this bug leads to very slow execution of boolean operations when a tool is infinite (e.g., section by plane, or cut by halfspace), since all the subshapes of the object hit in bounding box of the tool. Furthermore, it sometimes leads to impossibility to perform a boolean operation with the object if it contains "problem" edges even when they are situated very far from the tool. For details on this problem see the bugs OCC6502 and OCC6289. | ||||
