We exploit frame-to-frame coherence in animated sequences by transferring rendering results from a reference image to nearby viewpoints in space and time using a novel image warping algorithm based on fixed point iteration. By analyzing the behavior modalities of the iteration we establish a framework in which to define heuristics for providing the necessary guidance to the iteration. Additionally we derive local convergence criteria and use it to inform a new robust image warping algorithm. The resulting warping algorithms represent a unified reprojection kernel that we use to generate multiple effects including fast stereoscopic 3D, 30-to-60Hz post conversion, defocus blur and motion blur.
