Senior Project - UGRAPH


C Language Scientific Graphic Library for Streamlines and Vectors

Senior Project: 1989-1990
Victor Gurule, Risa Halim and Glenn Hostetler

Unidata is a program within the University Corporation for Atmospheric Research for improving the accessibility and usefulness of scientific data to atmospheric scientists at universities. The program provides software and support for systems that run on networks of scientific workstations in university departments. C language graphics display utilities are an important part of the Unidata software systems for capturing and displaying real time weather data. C language facilities for generating map backgrounds and overlaying contours of data fields were developed in one of last year's senior projects. However, some data are better displayed with velocity vectors and streamlines as opposed to contours. This project developed the velocity vector and streamline routines (similar in functionality to the FORTRAN routines in the NCAR Graphics package) and integrated them with the existing map and contour packages. All the output was done on X Windows displays using GKS for the vector graphics.
