Haptic display with force feedback is often necessary in sev-eral virtual environments. To enable haptic rendering of large datasets we
introduce Continuously-Adaptive Haptic Rendering, a novel approach to
reduce the complexity of the rendered dataset. We construct a continu-
ous, multiresolution hierarchy of the model during the pre-processing and
then at run time we use high-detail representation for regions around the
probe pointer and coarser representation farther away. We achieve this
by using a bell-shaped filter centered at the position of the probe pointer.
Using our algorithm we are able to haptically render one to two orders
of magnitude larger datasets than otherwise possible. Our approach is
orthogonal to the previous work done in accelerating haptic rendering
and thus can be used with them.
