Research Activities:
 
Virtual Sculpting with Haptic Interface
The goal of this system is to enable interactive modeling in a virtual environment such that the user can focus on the design intent. An interactive modeling method as shown in Fig. 1 is implemented with VR hardware and software to allow the user creating and modifying 3D free-form object in an advanced virtual environment. The system’s stereo viewing, motion tracking and haptic interface capabilities provide a friendly environment where the user can create freeform objects in an intuitive manner similar to sculpting in a physical environment.
