◆ Remove()

Standard_Boolean Graphic3d_BvhCStructureSet::Remove ( const Graphic3d_CStructure theStruct)

Removes the given structure from the set.

Returns
true if structure removed, otherwise returns false (structure is not in the set).

◆ Size()

virtual Standard_Integer Graphic3d_BvhCStructureSet::Size ( ) const
overridevirtual

Returns total number of structures.

Implements BVH_Set< T, N >.
