PVR: The parallel volume rendering package

PVR in a nutshell

Runs on the Intel Paragon (OSF/SUNMOS)
Tcl-based command front-end
Tk/Tcl GUI front-end
Ray casting renderer exploits Image-space, Object-space, and Time-Space parallelism
Content-based load balancing (click for MPEG movie)
Pipelined compositing

PVR Status

Currently under development (25,000+ lines of code). Have demonstrated the ability to render a 500 million voxel data set on the Intel Paragon using about 350 nodes -- once the data is loaded, a 120 frame animation can be computed in about 5 minutes.
