This video describes ongoing research in Mines ParisTech.
We propose intuitive shape modification techniques inside an immersive Virtual Reality system.
There are two types of shape descriptions. The first is the one used in the virtual reality display, it is a mesh model adapted to realtime visual feedback on modifications. The second is an analytic description, that is generated within a CAD engine.
The system performs a realtime bi-directional link between virtual reality shape description and the CAD analytic desciption.
