4D Volume Rendering with the Shear Warp Factorisation

Abstract

A novel approach for rendering time-varying data based on the Shear-Warp factorisation is presented. Reduction in storage space is achieved by detecting the changed areas within each volume and compressing them. Time-coherence is exploited by detecting and rendering the changes in every volume while spatial-coherence is exploited by utilising a data structure that allows easy volume update and stores information about the empty space within each volume.
