Haptic Paint


Our goal is to allow textures to be directly painted onto 3D models using a haptic device. The haptic device provides natural contact cues to the user.


Our approach is based on work we have done for a Virtual Prototyping project. We have developed methods to trace along 3D models using force feedback devices. These methods provide a single point of contact. In order to simulate a brush, we sample texture pixels near this point to measure the distance from the brush center. In this way, we are able to overcome the distortion of the mapping from texture space to 3D space.
