Résumé
This paper addresses haptic rendering for large data sets resulting from CFD (Computational Fluid Dynamics) applications. We present a new haptic interaction technique for volume rendering of isosurfaces. This method is based on an existing process [1]. This contribution makes it possible to take into account 3D regions presenting high frequency data. In addition, with this technique we can explore and understand complex data fields without having any intermediate geometrical representation (such as the polyhedral mesh provided by Marching Cubes [14]), thus having a very fast haptic rendering loop. Lastly, we led several psychophysical studies to assess the interest of this method for isosurface haptization.
