Representation of three-dimensional scenes using screened voxel expressions

We propose an approach far the generation and distribution of three-dimensional scenes that is practical on existing networks. In spite of needs and expectations from many fields, three-dimensional visualization? is not yet commonly used. Our approach is based on the idea that multimedia data should be both infrastructure-friendly and user-friendly. We represent three-dimensional objects using screened vox el expressions. This representation keeps the data size small enough so that existing network bandwidth is sufficient, and can be rendered efficiently enough (using the 3DDDA algorithm) so that low cost client computers can be used. In this paper we explain how to represent scenes using screened voxel expressions and give some examples.
