Methods

virtual void onUpdateBuffers_Wireframe()

Must be implemented in derived classes to update the geometric entities to be drawn in “m_*_buffer” fields.

virtual mrpt::math::TBoundingBox getBoundingBox() const

Evaluates the bounding box of this object (including possible children) in the coordinate frame of the object parent.
