Haptic Gdraw: A fun and Easy to Use 3D Haptically Enhanced Sculpting Program

We have developed a simple haptically-enhanced 3D sculpting application which utilizes Hermite spline-based primitives as building blocks to construct more complex solid models. To accomplish this, we have constructed a VR work environment which is intuitive and whose control affordances are made clear through the use of graspable handles. Haptics is used to support handle selection and provide physical constraints on handle movements consistent with their visual affordances. Our goal is to demonstrate how relatively simple haptic force constraints can combine with a visually intuitive and compelling environment to enable a program that is fun and easy to use.
