Abstract
Abstract Ray tracing exhibits visible temporal aliasing artifacts in interactive viewing of complex datasets. We present a technique to reduce scintillation in point sampled imagery by targeting new rays to intersection points from previous frames. Remaining artifacts are abated by blending between successive frames. The algorithm achieves a reduction in scintillation comparable to that of supersampling, but at a significantly lower cost. Sample animations are available on the website listed at the end of this paper.
