Interactive direct visualization of 3D data requires fast update rates and the ability to extract regions of interest from the surrounding data. Parallel volume rendering yields rates that make interactive control of image viewing possible for the first time. We have achieved rates as high as 15 frames per second by trading some function for speed. while(More)
We describe a software system on the Pixel-Planes 5 graphics engine that displays user-defined antialiased procedural textures at rates of about 30 frames per second for use in real-time graphics applications. Our system allows a user to create textures that can modulate both diffuse and specular color, the sharpness of specular highlights, the amount of(More)
We describe the VISTAnet gigabit testbed's visualization system, a parallel, interactive, multimodal renderer implemented on the Pixel-Planes 5 graphics engine. The system displays multiple superimposed data sets characterizing a 3D radiation treatment scenario. Its features are designed to facilitate comprehension of spatial relationships among(More)
