Interacting with direct volume rendering

Visualization researchers at the San Diego Supercomputer Center have written a program called Volume Explorer, or vx, which performs interactive direct volume rendering on the Volume Pro board. Using OpenGL, the GL Utility Toolkit and the Micro User Interface, vx generates the graphics and facilitates user interaction around the Volume Pro card. Regardless of the method, my colleagues and I have become very big fans of interactive direct volume rendering. This article shows some of our preliminary work with vx. On the screen, you can change and manipulate images at update rates of more than 30 frames per second.
