Senior Project - VISTA


Terrain Data Visualizer

Senior Project: 1991-1992
Jacqueline Atkinson, Karen Jackson, Micah Moore and Thomas Wilsher
Scientific Computing Division
Boulder, CO

The Scientific Visualization Group (SVG) of NCAR needed a high-level scientific visualization application which would offer a quick-look capability for plotting global terrain data overlaid with maps of political and/or continental boundaries from NCAR's EZMAP database. The terrain data was required to be rendered as a 3D surface with either a wire frame or as filled polygons.

The project allows scientists to view arbitrary rectangular regions of the surface of the earth, while controlling various aspects of the view. These include rotation of the viewed surface, the overlay of various boundaries, and the control of the colors used to represent the various elevations on the rendered surface. The software was written in C, using the X Window System, Motif graphical user interface toolkit, and PEX rendering package.
