2-D Macroscopic Texture Synthesis

Bennis, Chakib; Gagalowicz, Andre (Blackwell Publishing Ltd and the Eurographics Association, 1989)

We present a new macroscopic texture synthesis method based upon a hierarchical macroscopic texture model. Our model allows the composition of various patterns which can be themselves distorted spatially. Such a method is ...

2.5 Dimensional Graphics Systems

Herman, Ivan (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 ...

8th EUROGRAPHICS UK Conference

Willis, P.J. (Blackwell Publishing Ltd and the Eurographics Association, 1989)

Accelerated Radiosity Method for Complex Environments

Xu, Hau; Peng, Qun-Sheng; Liang, You-Dong (Eurographics Association, 1989)

As form-factor calculation costs about 90% of the computing time when applying radiosity approach for realistic image synthesis, it is of great significance to reduce the required computation, An accelerated radiosity ...

Adding Parallelism in Object Space to the Rendering Pipeline

Chapman, Paul A.; Lewis, Eric (Eurographics Association, 1989)

This paper analyses the problem of adding parallelism to the rendering pipeline and discusses the reasons for advocating an object-space partition. Consideration of the methods of work distribution and the rendering ...

Algorithm for Clpping Arbitrary Polygons

Andreev, Rumen D. (Blackwell Publishing Ltd and the Eurographics Association, 1989)

Algorithms for 2D Line Clipping

Skala, Vaclav (Eurographics Association, 1989)

New algorithms for 2D line clipping against convex, non-convex windows and windows that consist of linear edges and arcs are being presented. Algorithms were derived from the Cohen-Sutherland 's and Liang-Barsky s algorithms. ...

An Analysis of Modeling Clip

O Bara, Robert M.; Abi-Ezzi, Salim (Eurographics Association, 1989)

Modeling clip gives an application the ability to remove sections of an object in order to view internal detail. The clipping volume defied by modeling clip can be concave and disjoint, and is composed of a set of volumes ...

Anti-aliased Ray Tracing with Covers

Thomas, D.; Netravali, Arun N.; Fox, D.S. (Blackwell Publishing Ltd and the Eurographics Association, 1989)

A fast and effective object space method for antialiasing ray-traced pictures is introduced. Traditionally, anti-aliasing has been done using super-sampling. However, this is costly since it requires casting large numbers ...

Anti-Aliasing by Successive Steps with a Z-Buffer

Ghazanfarpour, D.; Peroche, B. (Eurographics Association, 1989)

We present a method allowing to solve the three problems arising when a scene is displayed with the z-buffer algorithm. The proposed algorithm only requires one extra memory bit per pixel and delivers good quality images. ...

Blending Rational B-Spline Surfaces

Bardis, L.; Patrikalakis, N.M. (Eurographics Association, 1989)

A method for blendin non uniform rational B-spline surface patches, either open or periodic, is developed. he blending surface is expressed in terms of an integral, bicubic B-spline patch. The blend ensures position and ...
