  Levy-Vehel, J.; Gagalowicz, A. (Eurographics Association, 1988)

  We present some new techniques for shape approximation with fractals, using Iterated Function System, a powerful method which allows good control on the resulting fractal. The main point discussed here can be stated as ...

• Animation of Stochastic Model-Based 3-D Textures 

  Gagalowicz, Andre; Ma, Song D. (Eurographics Association, 1988)

  We have previously shown the validity of a statistical model proposed by us for realistic textures. We have also shown how to use this model to map realistic textures onto a still surface of any shape and extent, maintaining ...

• Liberation from Rectangles: A Tiling Method for Dynamic Modification of Objects on Raster Displays 

  Slater, Mel; Davison, Allan; Smith, Mark (Eurographics Association, 1988)

  When graphics objects (also called segments) are used on raster display hardware, problems arise because of the mismatch between the high level requirements of object manipulation, and the low level representation from ...

• Outline Phase Control for Character Rasterization 

  Hersch, R. D. (Eurographics Association, 1988)

  Character rasterization on middle-resolution output devices (screens, laser printers) is one of the most difficult tasks in the domain of resolution-independent raster imaging. Low sampling leads to unacceptable low-quality ...

• A Simple Spectral Approach to Stochastic Modelling for Natural Objects 

  Anjyo, Ken-ichi (Eurographics Association, 1988)

  Stochastic modeling has been widely used in computer graphics to depict natural objects or phenomena. Various techniques are available, depending on what object is to be represented and what extent of realism to be achieved. ...

• Free-Form Surfaces Modeling by Evolution Simulation 

  Lienhardt, Pascal (Eurographics Association, 1988)

  We present in this paper a procedural method for modeling free-form, planar surfaces subdivisions, which allows simulating evolutions of such subdivisions. This method is founded on the common principles deduced from ...

• A Evalution of Some Three-Color Tiling Patterns 

  Alt, Paul; Cordonnier, Vincent (Eurographics Association, 1988)

  Some new technologies for information display use discrete arrays of cells or picture elements. Each cell displays a single color and the colors do not overlap as they do on a CRT screen. Colored cells are distributed on ...
