Abstract:
A three-dimensional (3D) object can be represented as a linear
combination of "blobs" (these are spherically-symmetric
smooth functions) each attached to one of an efficiently-arranged
grid of points in space. The representation problem becomes that
of calculating how much weight to give to each of the individual
blobs based on some given data. Surfaces defined by such a
representation are inherently smooth, allowing superior 3D
displays based on such representations to those obtained from the
traditional voxel-based representations. Volume visualization can
be achieved by efficient footprint algorithms and associated
hardware mappings.
