Interactive Product Development and Haptics in Virtual Reality with VrM3d

摘要

The VrM3d design tool has been created to investigate the utility of interactive design in virtual reality with force feedback. VrM3d uses two iterative stress approximation methods for reanalyzing part geometry as it is deformed as well as mesh-free analysis to avoid mesh distortion issues, subdivision volume free-form deformation for shape changes, fast collision detection routines, and haptic feedback tied to stress analysis results for shape manipulation. The application runs in virtual reality on a variety of platforms, from desktop computers to the C6 virtual environment at Iowa State University.
