Abstract

We present our work on phase space rendering. Every radiance sample in space has a location and a direction from which it is received. These degrees of freedom make up a phase space. The rendering problem of generating a discrete image from single radiance values is reduced to reconstruct a continuous radiance function from sparse samples in its phase space. The problem of reconstruction in a sparsely sampled space is solved by utilizing scattered data interpolation (SDI) methods. We provide numerical and visual evaluations of experiments with three SDI methods.
