Point light fields for point rendering systems


In this paper, we introduce the concept of point light fields for point-based rendering systems, analogous to surface light fields for polygonal rendering systems. We evaluate two representations, namely, singular value decomposition and spherical harmonics for their representation accuracy, storage efficiency, and real-time reconstruction of point light fields. We have applied our algorithms to both real-world and synthetic point based models. We show the results of our algorithm using an advanced point based rendering system.
