Introduction to MLML_DBASE Programs
The MLML DBASE family of programs described here provides many of the. algorithms used in oceanographic data reduction, general data manipulation and line graphs. These programs provide a consistent file structure for serial data typically encountered in oceanography. This introduction should provide enough general knowledge to explain the scope of the program and to run the basic MLML_DBASE programs. It is not
intended as a programmer's guide. (PDF contains 50 pages
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
Survey of currently available high-resolution raster graphics systems
Presented are data obtained on high-resolution raster graphics engines currently available on the market. The data were obtained through survey responses received from various vendors and also from product literature. The questionnaire developed for this survey was basically a list of characteristics desired in a high performance color raster graphics system which could perform real-time aircraft simulations. Several vendors responded to the survey, with most reporting on their most advanced high-performance, high-resolution raster graphics engine

Current and future graphics requirements for LaRC and proposed future graphics system
The findings of an investigation to assess the current and future graphics requirements of the LaRC researchers with respect to both hardware and software are presented. A graphics system designed to meet these requirements is proposed
A proposed C language binding for the Graphical Kernel System-3D
This thesis introduces a proposed C language binding definition for the International Standards Organization\u27s draft international standard of the Graphical Kernel System-3D. This work augments the earlier C language binding of the two dimensional version of the Graphical Kernel System commonly known as GKS. The proposed function interface will provide a basis for, if not a final, C language binding for the three dimensional version of the Graphical Kernel System --Abstract, page ii
An Overview of Computer Graphics Industry Standards.
This paper presents the status of the family of computer graphics standards that have been under development in recent years. In order to take advantage of the graphics standards, the industrial communities should be aware of what standards exist, and the relationship of the standards to each other. Since it is also beneficial to understand the process for the development of standards, the role of organizations in the standards-making field and the standardization process is presented.
This discussion will provide an introduction and reference source for the computer graphics standards for those who have a need to understand the emerging standards, but have no technical involvement in their development. A level of understanding is provided which will assist in determining whether or not a particular standard would be appropriate for an intended application, and if further research into the standard might be required
Data synthesis and display programs for wave distribution function analysis
At the National Space Science Data Center (NSSDC) software was written to synthesize and display artificial data for use in developing the methodology of wave distribution analysis. The software comprises two separate interactive programs, one for data synthesis and the other for data display
A Graphics Function Standard Specification Validator
A validation methodology is proposed and implemented for natural language
software specifications of standard graphics functions. Checks are made for
consistency, completeness, and lack of ambiguity in data element and function
descriptions. Functions and data elements are maintained in a relational
database representation. The appropriate checks are performed by sequences of
database operations. The relational database manager INGRES was used to support
a prototype implementation of the proposed technique. The methodology supports
the development of a scenario-based prototype from the information available in
the specification. This permits various function sequences to be checked
without implementation of the environment specified. The application of a
prototype implementation of the proposed methodology to the specification of
the Graphics Kernel System (GKS) software package demonstrates the
practicability of the method. Several inconsistencies in GKS related to the
definition of data elements have been identified
