When building enterprise applications that need to be accessed through a variety of client devices, developers usually strive to implement most of the business logic device-indepen...
We present a novel method for rendering shadow volumes. The core idea of the method is to locally choose between Z-pass and Z-fail algorithms on a per-tile basis. The choice is ma...
We present a system allowing real-time image based lighting based on HDR panoramic images. The system performs time-consuming diffuse light calculations in a preprocessing step, w...
This paper addresses the problem of pattern noise encountered in single-stage delta-sigma modulators in the presence of a DC input signal. By utilizing state-space matrices, we ex...
We present a method for automatically rendering pen-and-ink illustrations of trees. A given 3-d tree model is illustrated by the tree and a visual representation of the foliage us...
