HapticFlow: PDE-based mesh editing with haptics: Research Articles

This paper presents HapticFlow, a haptics-based direct mesh editing system founded upon the concept of PDE-based geometric surface flow. The proposed flow-based approach for direct geometric manipulation offers a unified design paradigm that can seamlessly integrate implicit, distance-field based shape modeling with dynamic, physics-based shape design. HapticFlow provides an intuitive haptic interface and allows users to directly manipulate 3D polygonal objects with ease. To demonstrate the effectiveness of our new approach, we developed a variety of haptics-based mesh editing operations such as embossing, engraving, sketching as well as force-based shape manipulation operations.
