DataSpace: 3-D Visualizations of Large Databases
Vinod Anupam, Shahid Shafi Dar, T. F. Leibfried, Eric D. Petajan · 1995
DataSpace is a system for interactive 3-D visualization and analysis of large databases. DataSpace utilizes the display space by placing panels of information, possibly generated by different visualization applications, in a 3 -D graph layout, and providing continuous navigation facilities. Selective rearrangements and transparency can be used to reduce occlusion or to compare or merge a set of images (e.g. line graphs or scatter plots) that are aligned and stacked in depth. A prototype system supporting the basic 3-D graphic operations (layout, zoom, rotation, translation, transparency) has been implemented. We provide several illustrative examples of DataSpace displays taken from the current system. We present the 3-D display paradigm, describe the query, layout and rendering steps required to create a display, and discuss some performance issues.
