    A fundamental light reflection model that takes into account the internal structure of cloth to render the peculiar gloss of cloth objects is presented. In developing this model, the microscopic structure of textiles was considered. The model represents fabric features such as fiber's cross-sectional shape or weave. By measuring the reflected light intensity from actual cloth objects of several ty... View full abstract»

    An algorithm for compactly and accurately capturing the illumination of a diffuse polyhedral environment caused by an area light source is presented. The algorithm constructs a discontinuity mesh that explicitly represents discontinuities in the radiance function as boundaries between mesh elements. A piecewise quadratic interpolant is used to approximate the radiance function, preserving the disc... View full abstract»

    The Image chip, which accelerates 3D rendering algorithms base on Bresenham's line drawing and Pineda's parallel polygon drawing algorithms, is discussed. With these algorithms, Image can directly draw lines, spans, and triangles in wireframe, hidden-line, and Gouraud-shading modes. Image also directly antialiases vectors or provides antialiasing information to enhance antialiasing of vectors or t... View full abstract»

    The multimedia video processor (MVP) architecture, which incorporates a variety of parallel processing techniques to deliver very high performance to a wide range of imaging and graphics applications, is described. The MVP combines, on a single semiconductor chip, multiple fully programmable processors with multiple data streams connected to shared RAMs through a crossbar network. Each of the inde...

    Logic-enhanced memory chips that can remove the rasterizer/frame buffer bottleneck which limits the performance of current image-generation architectures are discussed. Putting pixel memory on-chip with rasterizing processors provides the two to three orders of magnitude improvement in access rates needed to support realistic shading models and aliasing in interactive systems. Current high-perform... View full abstract»
