sgCGroup* sgBoolean::Union(const sgC3DObject& aOb, const sgC3DObject& bOb)
Description:
Creates a group of objects by joining two objects, i.e. all the objects with points lying on the first or on the second object.
Arguments:
aOb - first object,
bOb - second object.
Returned value:
Returns the pointer to a group of objects constructed by joining the arguments. If the objects are not intersecting or in case of an internal error the function returns NULL.
Note:
An internal error may occur in case you call this function for the surfaces or solids with self-intersections (these solids may be constructed, for example, by a number of kinematic operations).
The function for correcting self-intersections of solids is planned in the next library version.
