Abstract The Point-to-Point Protocol (PPP) [1] provides a standard method for transporting multi-protocol datagrams over point-to-point links. The PPP Compression Control Protocol [2] provides a method to negotiate an...

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 t...
