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)
A combination of segmentation tools and fast volume renderers that provides an interactive exploration environment for volume visualization is discussed. The tools and renderers include mechanisms that distribute volume data across multiple processors, as well as image compositing techniques and solutions to representation problems in the selection and(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)
With the increase in the amount of information available on the internet, there is a challenge of providing relevant and useful information to the interesting users on the basis of their interest although when user wants to search data of their interest, they have to search in whole databases, which is very tedious and time consuming too. So a system is(More)
