This video presents ongoing research in Mines ParisTech's Virtual Reality lab. The subject is developing tools for the modification of shapes and surfaces in immersive virtual reality systems. The objective here is to provide the user with a direct manipulation of the model. Direct manipulation consists of superimposing visualization and manipulation spaces. VR litterature often uses the term "colocalization". To do this we allow the user to interact with waypoints, which is very different from control points. Our hypothesis is that direct manipulation, using waypoints, is more intuitive, since the hand is very close to the shape compared to control points manipulation.
