TL;DR: A symmetric linear algorithm for the digital generation of line segments is described, where the same points are selected irrespective of the order of the end points.

TL;DR: GRAFEDIT is a general-purpose interactive graphical editor that provides means to create, modify, transform, copy, store and retrieve almost any kind of two-dimensional line diagrams on a CRT terminal.

TL;DR: The tensioning rationale for the rational spline is developed for use in an interactive mode with minicomputer and graphics terminal, but may also be used in a batch environment.

TL;DR: It is found that despite certain limitations, the graphics capability of a large scale interactive molecular modeling system (AIMS) provides a useful assortment of graphics which aid the researcher in model visualization and understanding.

TL;DR: This paper describes an algorithm for calculating a viewing direction which will render visible the entire object whenever this is possible, and will furthermore minimize distortion in the projected image.

TL;DR: Geans has been applied to various network models such as a transportation analysis problem, PERT/CPM planning, Petri Net analysis and a guidance system for an urban railway network, and moreover it is being applied to other analysis areas as evolving itself.

TL;DR: Abstract STRUKEDIT allows the user to create a drawing according to the principles of step-wise refinement and top-down design, and may be a useful tool in business administration, technical and industrial design, electronic design and in all areas that involve the representation of complex objects or structures.

TL;DR: This work presents the most unusual primitives, which have been developed for use with the MIRA system, which may be useful for almost anyone interested in the production of drawings.

TL;DR: HCS not only provides a significant compaction ratio but also renders processing operations such as map intersection or union easier and allows the use of variable scale.

TL;DR: PASCAL/Graph as discussed by the authors is a high-level programming language that offers data types, variables, constants and operators, with which the programmer can represent the actual world as a model inside the computer.

TL;DR: Two different approaches for the application of problem specific attributes to finite element models are discussed; in both approaches interactive computer graphics techniques and the use of a top-down program approach is emphasized.

TL;DR: Interactive computer graphics as a means of dealing with problems of optimal shape using the finite element method when the aspect ratios of elements degenerate is discussed.

TL;DR: Five software modules have been developed to introduce the student to the graphics terminal and to demonstrate its capabilities for making engineering drawings without requiring any programming skill on the part of the student.

TL;DR: The important features of the GRASS-Graphic Software System are its low cost, software character generation and a user-trainable character recognizer, which has been included.

TL;DR: A graphical editing and Dynamic Analysis system for VIbration Systems with arbitrary degrees-of-freedom (DAVIS) on PDP-11/34 minicomputer, developed in consideration of a network property of the systems and also enables us simultaneous analysis for some topologically unconnected systems.

TL;DR: An INTEractive Relational GRAphics Database (INTERGRAD) based on relational models has been developed to create, store, retrieve and update the data related to two dimensional drawings.

TL;DR: The Shepard and Maude methods are considered for interpolating points in two three-dimensional spaces by closed smooth curves because the interpolation depends upon the choice of a “pole” and is not unique and, thus, can be controlled at will up to some extent.

TL;DR: Some computer graphics options useful for both computation and display of three-dimensional motions within buried high-voltage power transmission lines as they undergo temperature changes (load cycling) are discussed.

TL;DR: In this article, the enhancement, inhibition and selection operators are discussed and a discussion of how they are used and their effect on a picture matrix is given. But the authors do not discuss the effect of these operators on the image.

TL;DR: A simple algorithm for hidden line Ruled Surface graphics, typically used in Radio Astronomy, is discussed using low cost microcomputer system built around Motorola 6800 processor and Matrox 256∗∗2 graphics module of raster size 256 × 256 points.
