This image of the electron wave function of C60 was generated using VFleet, running on 8 processors of the PSC's Cray T3D.

VFleet Distributed Volume Renderer

VFleet is a volume renderer, which is a program that produces color images from 3D volumes of data. This program can run either locally or in a distributed mode, meaning that it farms the work out over a network of workstations or a parallel computer. The operation of the user interface is pretty much identical in either case. It is intended for use in computational science, in that it can handle very large datasets representing multiple variables within the same physical system.

The rendering modules of VFleet will run on any Unix platform. The user interface requires a Unix platform running Motif. The distributed version requires that PVM is also installed.

VFleet is intended to be installed and run at your site.

VFleet was developed at the Pittsburgh Supercomputing Center with major support from the Grand Challenge Cosmology Consortium.

This software is currently at release 1.1. Improvements since the previous release include:

• volume masking
• optional trilinear interpolation
• optional 3D mipmapping
• better camera control
• more complete scripting support
