Colour quantization is an established method for the reproduction of high visual quality colour imagery on systems with limited frame buffer resources. The ever increasing demand for fast and image/graphic intensive applications for cheap desktop platforms has called for greater savings in display and storage resources and simple, easy to implement architectures. Because human visual informatio...

The propagation and reflection of electromagnetic waves in a three-dimensional environment is simulated, and realistic images are produced using the resulting light distributions and reflectance functions. A finite difference time domain method is employed to advance the electric and magnetic fields in a scene. Surfaces containing wavelength scaled structures are created, the interaction of the...

A metallic paint scheme for an architectural wall is created using computer aided color appearance design techniques. New computer graphic hardware that allows real-time rendering of complex reflectance functions is employed to produce photo-realistic images of the metallic paint applied to the surface of the wall. An interpolation scheme is developed that permits one and two dimensional metall...

Recent advances in the computer graphics of woven images on arbitrary surfaces in 3-space motivate the development of weavings for higher genus surfaces. Our paradigm differs markedly from what Grünbaum and Shepard have provided for the plane. In particular, we demonstrate herein how weavings on surfaces in 3-space are inducible from graph imbeddings on surfaces in 3-space. Moreover, we show th...

Computer-aided learning (CAL) has great potential in facilitating learning. In medical education, several approaches using CAL have been used. In this paper, we present a novel software platform which we developed to provide a virtual learning environment to support anatomy teaching and learning. This learning platform provides accurate, interactive models which are derived from actual CT and f...

Over the past five years, computer-generated images (CGIs) have become commonplace as a means to market urban redevelopments. To date, however, they have been given relatively little attention as a new form of visualising the urban. This paper argues that these CGIs deserve more attention, and attention of a particular kind. It argues that, instead of approaching them as images situated in urba...
