We present an intuitive interface for painting on unparameterized
three-dimensional polygon meshes using a 6D Polhemus space tracker as
an input device. Given a physical object we first acquire its surface
geometry using a Cyberware scanner. We then treat the sensor of the
space tracker as a 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.
