Abstract
. The known sampling methods can roughly be grouped into regular and irregular sampling. While regular sampling can be realized efficiently in graphics hardware, it is prone to inter-pixel aliasing. On the other hand these artifacts can easily be masked by noise using irregular sampling which, however, is more expensive to evaluate as it lacks the high coherence of a regular approach. We bridge this gap by introducing a generalized sampling scheme that smoothly blends between regular and irregular sampling. By interleaving the samples of regular grids in an irregular way, we preserve the high coherence and efficiently reduce inter-pixel aliasing thus significantly improving the rendering quality as compared to previous approaches. 1
