Abstract: We applied an image-based modeling and rendering technique to reduce
the data size of a CG model to be obtained as a visualization result. To date,
this technique has been applied to the reconstruction of 3D graphical models
from real objects; the size of the models can be reduced effectively because
both color information and geometric information can be reduced. We applied a
silhouette-and-voxel method that does not require design data for geometric
simplification. Using our system, we simplified two models, one of which,
involving medical data, was reduced by about 85% in file size. An accompanying
subjective quality test showed that our approach maintains approximately the
same visual quality as the geometric simplification method traditionally used.
