Returns the structure corresponding to the given ID.

◆ Remove()

Standard_Boolean OpenGl_BVHClipPrimitiveSet::Remove ( const OpenGl_Structure 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 OpenGl_BVHClipPrimitiveSet::Size ( ) const
overridevirtual
