The Clockworks: An Object-Oriented Computer Animation System
(Eurographics Association, 1987)
The Clockworks is an object-oriented computer animation system developed at RPl's Center for Interactive Computer Graphics (CICG). The Clockworks has the ability to model and graphically simulate complex 3-D engineering ...
Splines for Engineers
(Eurographics Association, 1987)
This paper introduces the concept of interpolation consistency. It is claimed that this property is an essential one for splines that are intended for use in Computer Aided Design. Consistency is defined as the property ...
Experiences in Implementing Postscript
(Eurographics Association, 1987)
This paper describes an implementation of POSTSCRIPT for previewing use on workstations with high resolution bitmapped displays. It discusses implementation of storage management, area fill and line drawing, imaging, fonts ...
A New Algorithm for Contour-plotting
(Eurographics Association, 1987)
A new algorithm for contour-plotting is introduced. The input function, tabulated or in a subroutine description, is approximated by an interpolation function. The contours of this approximating function are drawn piecewise ...
A New Algorithm of Space Tracing Using a CSG Model
(Eurographics Association, 1987)
This paper describes a new algorithm of space tracing. Scenes are modeled by a CSG tree. Space is subdivided regularly into 3D regions called boxes. With each box is associated a subtree which is the restriction of the ...
A Shareable Centralised Database of KRT3 - A Hierarchical Graphics System Based on PHIGS
(Eurographics Association, 1987)
The Programmer’s Hierarchical Interactive Graphics System (PHIGS), currently under development by ISO, is a specification of a set of functions for device-independent computer graphics programming, supporting dynamic ...
A Metric for Computing Adaptive Detail in Animated Scenes Using Object-Oriented Programming
(Eurographics Association, 1987)
A spatial metric for adapting the level of detail in a modelled object to achieve a convincing degree of realism on a display is formulated and illustrated with a simple implementation. This spatial metric is designed to ...
Generative Scene Modelling
(Eurographics Association, 1987)
We describe a new theory of scene modelling that includes generative processes as integral components of scene descriptions. A single, uniform treatment of generative processes replaces the variety of ad hoc mechanisms ...
Interaction Management in CAD Systems with History Mechanism
(Eurographics Association, 1987)
User friendliness is one of the unresolved problems in CAD systems. There are many possible directions for improving user friendliness. Understanding of the modeling process is one of the most important directions. It is ...
An Algorithm for 3D Scan-Conversion of Polygons
(Eurographics Association, 1987)
A three-dimensional (3D) scan-conversion algorithm, that scanconverts 3D planar polygons into their discrete voxel-map representation within a Cubic Frame Buffer (CFB), is presented. The algorithm, which is a variation of ...
