Pressure visualization (PreViz) package version 1.0 user's guide

The Pressure Visualization (PreViz) package is a software tool which merges a wireframe model of the test aircraft with pressure data represented as a series of displacement vectors normal to the aircraft's skin. The PreViz package automates much of the researcher's data reduction effort, reduces the time required to review large amounts of pressure data, presents the data more clearly than tabular listings, and provides a wireframe description for a black and white graphic suitable for a technical publication (the actual graphic images must be created by a local package since PreViz has no graphics capability). Although designed for pressure data, the PreViz package works equally well for any surface property (such as structural loading or skin temperature). Written in ANSI-standard FORTRAN 77 and self-contained, PreViz executes in UNIX, VAX/VMS, and CDC/NOS host environments.
