21 | class RoughShapeIntersector from BOPTools |
22 | |
23 | ---Purpose: The class RoughShapeIntersector describes the algorithm of |
24 | -- intersection of bounding boxes of |
25 | -- shapes stored in ShapesDataStructure. |
26 | -- It stores statuses of intersection in 2 dimension array. |
27 | |

47 | -- Warning: |
48 | -- Using this function, after the destructor of |
49 | -- the object pointed by PDS (see constructor) |
50 | -- was invoked, lead to crash. |

55 | ---C++: return const & |
56 | ---Purpose: |
57 | -- Returns 2 dimension array of status flags. |
58 | -- First indices of the array corresponds to indices of |
59 | -- subshapes of Object of myPDS. |
60 | -- Second indices of array corresponds to indices of |
61 | -- subshapes of Tool of myPDS. |
