• FRACTIONAL BROWNIAN RELIEF : AN EXACT LOCAL METHOD 

  FELLOUS, A.; GRANARA, J.; HOURCADE, J. C. (The Eurographics Association, 1985)

  Fractional Brownian process has been widely used for computer rendering of terrain models. The implementation constraints in Computer Graphics have led to the use of recursive methods, based on some local properties of ...

• A GENERALISATION OF THE TIMMER BLENDING FUNCTIONS FOR BEZIER-TYPE CUBIC CURVES 

  NTOKO, NZUMBE-MESAPE (The Eurographics Association, 1985)

  Alternative blending functions are derived for a Bezier-type cubic curve touching the middle side of its control polygon. Three shape parameters are used which determine the point on the middle side of the control polygon ...

• GENERALIZATION OF CONTOUR TRACKING IN IMAGE SYNTHESIS, AND APPLICATION 

  Hegron, Gerard (The Eurographics Association, 1985)

  In this report, we propose to present most of the treatments about convex and nonconvex colored shapes from a data structure of their contour which is the general approach of contour tracking . Contour filling and oblique ...

• EXTENDING GKS TO A DISTRIBUTED ARCHITECTURE 

  R.Bettarini,; G.Faconti,; L.Moltedo, (The Eurographics Association, 1985)

  The recently adopted standards in the fields of computer networks and computer graphics has given to the opportunity to start a project to develop a distributed model of the Graphical Kernel System (GKS). The aim of this ...

• NEM: A LANGUAGE FOR ANIMATION OF ACTORS AND OBJECTS 

  Marino, Giuseppe; Morasso, Pietro; Zaccaria, Renato (The Eurographics Association, 1985)

  The animation of actors and objects is considered in the framework of knowledge representation, with particular regard to motor knowledge. In our opinion, a formal model for motor knowledge should fill a gap between action ...

• A Three-Dimensional Shaded Display Method for Voxel-Based Representation 

  OHASHI, Toshiaki; UCHIKI, Tetsuya; TOKORO, Mario (The Eurographics Association, 1985)
