Abstract
This paper presents a technique to carry out progressive transmission
of a volume data set using a hierarchical index of the data set. The intermediate
data transmitted can be used as a complete representation, allowing the
client to perform any computation on the volume and to generate any isosurface.
The experiments performed show that a good approximation can be achieved
for medical data sets with less than ten per cent of the data transmitted.
The hierarchical index used is a compressed BONO index (cell octree), that
is also used to speed up the isosurface generation.
