    So far, the problem of global illumination calculation has almost exclusively been approached from an algorithmic point of view. We propose an architectural approach to global illumination. The proposed rendering architecture Vision is derived from a model of the physical rendering process, which is subsequently mapped onto an object-oriented hierarchy of classes. This design is powerful and flexi... View full abstract»

    The hemicube estimates of form factors are based on a finite set of sample directions. We obtain several optimal arrangements of sample directions, which minimize the variance of these estimates. They are based on changing the size or shape of the pixels or the shape of the hemicube, or using non-uniform pixel grids. The best reduces the variance by 43%. The variance calculation is based on the as... View full abstract»

  • Visualization of multidimensional shape and texture features in laser range data using complex-valued Gabor wavelets

    The paper describes a new method for visualization and analysis of multivariate laser range data using complex valued non orthogonal Gabor wavelets (D. Gabor, 1946), principal component analysis and a topological mapping network. The initial data set that provides both shape and texture information is encoded in terms of both amplitude and phase of a complex valued 2D image function. A set of care... View full abstract»

    Networks are critical to modern society, and a thorough understanding of how they behave is crucial to their efficient operation. Fortunately, data on networks is plentiful; by visualizing this data, it is possible to greatly improve our understanding. Our focus is on visualizing the data associated with a network and not on simply visualizing the structure of the network itself. We begin with thr... View full abstract»

  • Real time responsive animation with personality

    Building on principles from prior work on procedural texture synthesis (K. Perlin, 1985), we are able to create remarkably lifelike, responsively animated characters in real time. Rhythmic and stochastic noise functions are used to define time varying parameters that drive computer generated puppets. Because we are conveying just the “texture” of motion, we are able to avoid computatio... View full abstract»

  • Volume rendering of DCT-based compressed 3D scalar data

    The paper proposes a scheme to perform volume rendering from compressed scalar data. Instead of decompressing the entire data set before rendering, blocks of data are decompressed as needed. Discrete cosine transform based compression technique is used to illustrate the method. The data is partitioned into overlapping blocks to permit local rendering and allow easy parallelization. Compression by ... View full abstract»
