Constructor.

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::TBoundingBoxf internalBoundingBoxLocal() const

Must be implemented by derived classes to provide the updated bounding box in the object local frame of coordinates.

This will be called only once after each time the derived class reports to notifyChange() that the object geometry changed.
