Abstract

Advanced graphics techniques for rendering photo-realistic scenes have seen little use in scientific visualization due to uncertainty as to whether the higher computational cost is worth the increased visual realism. This paper presents a new low-cost method, containing more visual cues for interpreting complex dynamic data. The method has been used to visualize neurobiology data with neuron synapse modeled as a radiative burst. Images are produced at the rate of 3 per minute for a 395 neuron simulation. Implementation of this method was accomplished using the Illumination Networks energy-balance rendering technique introduced at SIGGRAPH '89. Work is underway to parallelize the algorithm which should yield interactive speeds. Two exclusive features of this method are (1) the ability to represent dynamic changes in data by mapping these changes to brightness of polyhedral objects in an abstract data space; the light emitted by these objects into the surrounding scene forms another dimension for data interpretation, and (2) the ability to better represent complex data geometry on a finite resolution computer screen. Because objects emit light, their effects on the environment can be seen even if the objects are smaller than a pixel when mapped to the screen or are obscured by other objects in the scene.
