Brushing techniques for exploring volume datasets

Describes several visualization techniques based on the notion of multi-resolution brushing to browse large 3D volume datasets. Our software is implemented using public-domain libraries, and is designed to run on average-equipped desktop computers such as a Linux machine with 32 MBytes of memory. Empirically, our system allows scientists to obtain information from a large dataset with over 8.3 million numbers in interactive time. We show that very large scientific volume datasets can be accessed and utilized without expensive hardware and software.
