| Abstract |
We implement an interactive 3D painting application that stores paint
in an octree-like GPU-based adaptive data structure. Interactive
painting of complex or unparameterized surfaces is an important
problem in the digital film community. Many models used in production
environments are either difficult to parameterize or are
unparameterized implicit surfaces. We address this problem with a
system that allows interactive 3D painting of complex,
unparameterized models. The included movie demonstrates interactive
painting of a 817k polygon model
with effective paint resolutions varying between 64^3 to
2048^3. Our implementation differs from previous
work
in two important ways: first, it uses an adaptive data structure
implemented entirely on the GPU, and second, it enables interactive
performance with high quality by supporting quadlinear (mipmapped) filtering and fast, constant-time data accesses.
