  • Constant-Time Filtering by Singular Value Decomposition? 

    Gotsman, Craig (Blackwell Science Ltd and the Eurographics Association, 1994)
    We present a technique implementing space-variant filtering of an image, with kernels belonging to a given family, in time independent of the size and shape of the filter kernel support. The essence of our method is efficient ...

  • A Survey of Shading and Reflectance Models 

    Schlick, Christophe (Blackwell Science Ltd and the Eurographics Association, 1994)
    Since the beginning of computer graphics, three decades ago, a large number of models intended to describe the behaviour of light on a given point of a surface have been proposed. Almost every author uses his own terminology ...

  • Wavelet Projections for Radiosity 

    Schröder, Peter; Gortler, Steven J.; Cohen, Michael F.; Hanrahan, Pat (Blackwell Science Ltd and the Eurographics Association, 1994)
    One important goal of image synthesis research is to accelerate the process of obtaining realistic images using the radiosity method. Two important concepts recently introduced are the general framework of projection methods ...

  • Five-dimensional Adaptive Subdivision for Ray Tracing 

    Simiakakis, G.; Day, A. M. (Blackwell Science Ltd and the Eurographics Association, 1994)
    This paper presents a directional subdivision method for speeding up ray tracing. This method is easy to use, because it automatically adapts the subdivision to the scene relieving the user from having to set parameters ...

  • Making Shaders More Physically Plausible 

    Lewis, Robert R. (Blackwell Science Ltd and the Eurographics Association, 1994)
    There is a need to develop shaders that not only"look good", but are more physically plausible. From physical and geometric considerations, we review the derivation of a shading equation expressing rejected radiance in ...

  • A Theoretical Framework for Physically Based Rendering 

    Lafortune, Eric P.; Willems, Yves D. (Blackwell Science Ltd and the Eurographics Association, 1994)
    In this paper we introduce the concept of the global reflection distribution function which allows concise formulation of the global illumination problem. Unlike previous formulations it is not geared towards any specific ...
