In this work, we present our experiences in disseminating the results of two studies to national audience. The resulting visualizations and press releases allowed the studies' researchers to educate a national, if not global, audience. Continue reading

This paper shows that images constructed with non-pinhole cameras improve approximation quality at little additional cost provided that the non-pinhole camera offers fast projection. We demonstrate the advantages of non-pinhole depth images in the context of reflections, refractions, relief texture mapping, and ambient occlusion. Continue reading

We present a system for visualizing memory reference traces, the records of the memory transactions performed by a program at runtime. The visualization consists of a structured layout representing the levels of a cache and a set of data glyphs representing the pieces of data in memory being operated on during application runtime.

Multiperspective images (MPIs) show more than what is visible from a single viewpoint and are a promising approach for alleviating the problem of occlusions. We present a comprehensive user study that investigates the effectiveness of MPIs for 3-D scene exploration. The results of our experiments show that MPIs can greatly outperform conventional images.
