摘要:

AbstractRay‐casting techniques provide a very general framework in which many problems can be solved in a much easier way than with conventional methods. This is particularly true for the illumination model when a high level of realism is required. Another interesting feature of ray‐casting is its ability to display a wide class of algebraic surfaces with a minimum of approximation. Both aspects are developed in this paper where a full lighting model, based on a theoretical approach, is presented. Then, an algorithm for the display of surfaces of revolution is described.Computation time is the major drawback of ray‐tracing. Special purpose parallel processors seem to offer a good price/performance ratio compared to the use of supercomp

摘要:

AbstractThe human visual system's capacity and capability to process colour can be applied as a design criterion for colour information displays. This paper reviews key elements in the visual domain of colour, encompassing the visual, perceptual, and cognitive modes and develops a series of recommendations for effective colour usage based on these elements.

摘要:

AbstractThe use of computers in art is not new: examples are given of past and present applications. Three categories are mentioned: computer as tool, as origin of concepts and metaphors, and as controller. The use of the computer in art gives rise to the idea of computing as representation‐ rather than just information‐processing. Thus the computer can be said to ‘belong’ to artists and designers, and can be seen as a qualitative device. It is argued that computing is ‘really’ an art or design activity, and that this has implications for art, design an
