New Methods for Improving the GKS Fill Area Output Primitive
(Blackwell Publishing Ltd and the Eurographics Association, 1987)
The fill area primitive is one of the most powerful primitives of GKS and its derivatives (GKS-3D, PHIGS etc.). Since its specrfication is extremely general, it is important to explore new approaches to achieve higher ...

On The Projective Invariant Representation of Conies in Computer Graphics
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
A general formulation for conies and conic arcs for the purpose of computer graphics is given, based on principles and theorems of projective geometry. This approach allows the approximation of these curves by line segments ...
A Means to Improve the GKS-3D/PHIGS Output Pipeline Implementation
(Eurographics Association, 1987)
The output pipeline of GKS-3D/PHIGS isexamined to find some possible points where the implementation could be improved to raise efficiency while remaining strictly within the scope of the Standards. Some interesting results ...
2.5 Dimensional Graphics Systems
(Eurographics Association, 1989)
The outline of an extension of traditional 2D graphics systems is given. This extension is aimed at supporting a three dimensional application program, without incorporating full viewing into the general graphics system ...
