Abstract

We describe the operational principles of a scalable hardware accelerator for volume rendering. The basic philosophy is to provide an atomic unit which already provides sophisticated volume graphics at interactive rendering speed. Realtime speed can then be achieved by operating multiple units in par allel. The basic unit consists of just four VLSI chips and the volume memory and thus meets the requirements of a small size and low costs. Never theless it provides arbitrary perspective projections (e.g., for walk-throughs), Phong shading, a freely moveable light source, depth-cueing and interac tive, non-binary classification (semi-transparent display) at a frame rate of about 2.5Hz for 256 3 data sets.
