Prism

Research archive · original page Research.Prism · last recorded update 2009-11-14

This is a 1970s algorithm and implementation for displaying 3D prism maps showing data depending on geographic regions by raising a prism above each region. The program preprocessed the 2D map in advance so that new data could be displayed, with hidden surfaces removed, quickly. Titles include:
