摘要:
AbstractAlgorithms for the translation and scaling of a digitised image are described. The algorithms have been designed to work on a transputer network which has a simple topology. This transputer network was originally proposed for the arbitrary rotation operation on digitised images1. The data structure used to represent the image is closely related to mnlength encoding. Both operations can be performed in real time on non trivial images.

摘要:
AbstractThis report investigates the problems involved in implementing the GKS 2D graphics standard in Occam. Whilst some of the detail is language specific, similar problems arise with implementations in any parallel system and the paper therefore has wider relevance. The main problems were found to be the lack of data types in Occam, parallel calls to the GKS implementation (which assumes a sequential command stream) and implementing a truly parallel GKS kernel. None of these problems appears to be insuperable, particularly if a preprocessor is used to overcome the potential communication and network conflicts which are possible in a parallel graphic system.

摘要:
AbstractMethods for realistic image synthesis are described. Exact mathematical establishment of reflectance models is presented, together with the development of feasible reflectance models meeting the energy balance. A new bidirectional reflectance type, separable reflectance, is introduced. Necessary and sufficient conditions for the iterative solution of the linear equation system of interreflection are presented. Lastly, a new method of inserting numerically defined objects into real optical surroundings is described.

摘要:
AbstractThe goals of the bulk of commercial computer systems for graphics and animated film/video are different from the kind of systems involving the production of art. The former systems are developed for industrial application. Accurate technical communication and precise representation of measures are the main goals of the drawings and die coloured plates intended for industrial application.In the arts, however, the main goal of a drawing, a painting, or an animated film/video is beauty. The visual artist searches for an equilibrium between proportions of different shapes and an equilibrium between different colours. A system able to help in this search must therefore have its roots in art, i.e. the so‐called modern art. Starting from my experience in painting, in animated film by pencil drawing, and in computer animation, I concluded that a scene could be represented very effectively and accurately by the technique of painting and drawing.The system presented for automatic painting of scenes within a 3D space that are changing in time, is based on the tradition of drawing and painting. The system must be applicable within the visual arts and video production. An experimental computer animation systemSIAS (Strokes Interpreted Animated Sequences)has been developed which produces coloured shapes that are similar to the strokes put on a canvas by a painte
