Efficient Image-Based Methods for Rendering Soft Shadows

Presents two efficient image-based approaches for computation and display of high-quality soft shadows from area light sources: Layered attenuation maps and coherence-based raytracing. Authors: Maneesh Agrawala, Ravi Ramamoorthi, Alan Heirich and Laurent Moll.

Improved Noise by Ken Perlin, Reference Implementation

An implementation in java of Perlin's 2002 SIGGRAPH paper (available in PDF format) describing a improved noise generating function.

Eliminating Popping Artifacts in Sheet Buffer-Based Splatting

Splatting is a fast volume rendering algorithm which achieves its speed by projecting voxels in the form of pre-integrated interpolation kernels, or splats. By Klaus Mueller and Roger Crawfis.

Robust Monte Carlo Methods for Light Transport Simulation

Eric Veach Ph.D. dissertation describes light transport problems in computer graphics and develops new Monte Carlo techniques that greatly extend the range of input models for which light transport simulations are practical.

Radiance Technical Papers

Various papers describing the free radiance highly accurate ray-tracing software system for UNIX computers.

Smoke Simulation for Large Scale Phenomenas

Nick Rasmussen, Duc Quang Nguyen, Willi Geiger and Ronald Fedkiw presents an efficient method for simulating highly detailed large scale participating media such as nuclear explosions.

Ray Tracing on Programmable Graphics Hardware

Timothy J. Purcell, Ian Buck, William R. Mark, and Pat Hanrahan evaluate trends in programmability of the graphics pipeline and explain how ray tracing can be mapped to graphics hardware.

All-Frequency Shadows

Ren Ng, Ravi Ramamoorthi and Pat Hanrahan presents a method, based on pre-computed light transport, for real-time rendering of objects under all-frequency, time-varying illumination represented as a high-resolution environment map. This gives good shadows.

Animation and Rendering of Complex Water Surfaces

Douglas Enright, Steve Marschner and Ronald Fedkiw describes a method designed to produce visually plausible water effects, for example the pouring of water into a glass and the breaking of an ocean wave.

Bidirectional Estimators for Light Transport

Eric Veach and Leonidas J. Guibas study techniques for reducing the sampling noise inherent in pure Monte Carlo approaches to global illumination.

Henrik Wann Jensen's Publications

A list of publications mainly about Photon Mapping, Global Illumination and rendering natural phenomenon such as fire, skin and smoke.

Symplectic Raytracing: Raytracing with Hamiltonian Dynamics in Blackhole Spacetime

Describes a method to visualize the curved spacetime around blackholes. By Tetsu Satoh, Haruo Takemura and Naokazu Yokoya.

Global Illumination Compendium by Philip Dutré

A compendium containing most of the useful formulas and equations for global illumination algorithms.

Computer Graphics Research Group, Katholieke Universiteit Leuven, Belgium

Research mostly center around global illumination and monte carlo ray tracing. Contains some environment maps, a description of a Cornell box experiment, Publications and the RenderPark ray tracer.
