virtual geom::AlignedCuboid GetBoundingBox ( bool  use_tf = false  )  const [virtual]

returns the bounding box of this object

The bounding box, i.e. the left-bottom-front and the right-top-back corner of the object, is obtained with this method. The single boolean parameter denotes whether to return local coordinates or global scene coordinates; global scene coordinates are local coordinates with the object's transformation (if present) applied. The default is false, i.e. return local coordinates.
