Summary: 3D Painting on Scanned Surfaces

Computer Science Department
We present an intuitive interface for painting on unparameterized
three-dimensional polygon meshes using a 6D Polhemus space
tracker asan input device. Given a physical object we first acquire
its surface geometry using a Cyberware scanner. We then treat the
sensorof the spacetracker asa paintbrush. As we move the sensor
over the surface of the physical object we color the corresponding
locations on the scanned mesh. The physical object provides a
natural force-feedback guide for painting on the mesh, making it
intuitive and easy to accurately place color on the mesh.
