4. Methods
We have developed an intuitive 3D interface for painting on 3D
computer models, using the sensor of a Polhemus 6D tracker as a
paintbrush. The fundamental feature of our system is that a physical
object provides a force feedback guide for painting. Our system is
fast enough to paint a mesh in real time as the sensor is moved over
the physical surface, giving the user a sense of directly painting on
the mesh. With this system there is no need to perform a
transformation from 2D input space to the 3D mesh surface, as is
required by other 3D painting systems that use a 2D input device. Also
unlike other 3D painting systems, the meshes we paint do not need to
be parameterized in any way. With our system an artist who is
experienced with painting on 3D physical objects can almost directly
apply that experience to painting on surface meshes.
