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.
Approach
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.
