Modular Radiance TransferModular Radiance Transfer (MRT) models coarse-scale, distant indirect lighting effects in scene geometry that scales from high-end graphics processing units (GPUs) to low-end mobile platforms. MRT eliminates scene-dependent precomputation by storing compact transport on simple shapes, akin to bounce cards used in film production. Bradford J. Loos, University of Utah |

LightSlice: Matrix Slice Sampling for the Many-Lights ProblemThis paper presents LightSlice, an algorithm that efficiently solves the many-lights problem for large environments with complex lighting. Our algorithm effectively exploits both the global and local structure of the light transport matrix by clustering matrix columns independently for each slice (group of neighboring rows) of the matrix. Jiawei Ou, Dartmouth College |

Practical Filtering for Efficient Ray-traced Directional OcclusionWe give a frequency analysis of shadow light fields using distant illumination with a general bidirectional reflectance distribution function (BRDF), allowing us to share occlusion ray information even among complex receivers. We also present a new rotationally invariant filter that easily handles samples spread over a large angular domain. Kevin Egan, Columbia University |

Progressive Photon BeamsWe present progressive photon beams, a new consistent rendering algorithm capable of simulating extremely complex lighting in both homogeneous and heterogeneous media efficiently. Wojciech Jarosz, Disney Research Zurich |
