IMAT graphics manual

The Integrated Multidisciplinary Analysis Tool (IMAT) consists of a menu driven executive system coupled with a relational database which links commercial structures, structural dynamics and control codes. The IMAT graphics system, a key element of the software, provides a common interface for storing, retrieving, and displaying graphical information. The IMAT Graphics Manual shows users of commercial analysis codes (MATRIXx, MSC/NASTRAN and I-DEAS) how to use the IMAT graphics system to obtain high quality graphical output using familiar plotting procedures. The manual explains the key features of the IMAT graphics system, illustrates their use with simple step-by-step examples, and provides a reference for users who wish to take advantage of the flexibility of the software to customize their own applications

Graphics mini manual

The computer graphics capabilities available at the Center are introduced and their use is explained. More specifically, the manual identifies and describes the various graphics software and hardware components, details the interfaces between these components, and provides information concerning the use of these components at LaRC

User's manual for EZPLOT version 5.5: A FORTRAN program for 2-dimensional graphic display of data

EZPLOT is a computer applications program that converts data resident on a file into a plot displayed on the screen of a graphics terminal. This program generates either time history or x-y plots in response to commands entered interactively from a terminal keyboard. Plot parameters consist of a single independent parameter and from one to eight dependent parameters. Various line patterns, symbol shapes, axis scales, text labels, and data modification techniques are available. This user's manual describes EZPLOT as it is implemented on the Ames Research Center, Dryden Research Facility ELXSI computer using DI-3000 graphics software tools

Raster Metafile and Raster Metafile Translator

The intent is to present an effort undertaken at NASA Langley Research Center to design a generic raster image format and to develop tools for processing images prepared in this format. Both the Raster Metafile (RM) format and the Raster Metafile Translator (RMT) are addressed. This document is intended to serve a varied audience including: users wishing to display and manipulate raster image data, programmers responsible for either interfacing the RM format with other raster formats or for developing new RMT device drivers, and programmers charged with installing the software on a host platform

Ada and the graphical kernel system

Since the introduction of the standard language in 1983, Ada has been the subject of controversy about its capabilities and its desirability. Proponents have claimed that Ada may be the ultimate computer language because it is a high-level, structured language that may be used in applications ranging from controlling jet fighters to business. Detractors have argued that Ada\u27s very versatility may be its undoing because it can do many things but not as well as more specialized languages. This thesis attempts to evaluate the capabilities and suitability of Ada for large projects by using it to implement the Graphical Kernel System

Scientific Visualization Using the Flow Analysis Software Toolkit (FAST)

Over the past few years the Flow Analysis Software Toolkit (FAST) has matured into a useful tool for visualizing and analyzing scientific data on high-performance graphics workstations. Originally designed for visualizing the results of fluid dynamics research, FAST has demonstrated its flexibility by being used in several other areas of scientific research. These research areas include earth and space sciences, acid rain and ozone modelling, and automotive design, just to name a few. This paper describes the current status of FAST, including the basic concepts, architecture, existing functionality and features, and some of the known applications for which FAST is being used. A few of the applications, by both NASA and non-NASA agencies, are outlined in more detail. Described in the Outlines are the goals of each visualization project, the techniques or 'tricks' used lo produce the desired results, and custom modifications to FAST, if any, done to further enhance the analysis. Some of the future directions for FAST are also described

Computer graphics standards for man modelling

The human being is arguably one of the most nonstandard and unpredictable components of all systems. Thus, in many application areas of computer-aided design, there is a need to model the physical aspects of humans alongside models of workplace and equipment. The paper briefly describes the Sammie systems, a long-established and succesful computer-aided design system that has fulfilled this requirement across a wide range of application areas. Recently, much development work has been aimed at incorporating a range of graphics and data-exchange standards into the Sammie software. These experiences are described, together with observations on their apparent limitations and advantages. In particular, the Programmer's Hierarchical Interactive Graphics System (Phigs), its extension to Phigs-Plus, the Computer Graphics Metafile (CGM), the Initial Graphics Exchange Specification (iges), and X-Windows with the Phigs extension (Pex) are considered
