Light Transport

Light transport research focuses on modeling and simulating how light interacts with objects and scenes, aiming to accurately render images and reconstruct 3D scenes from observations. Current efforts concentrate on improving the efficiency and accuracy of light transport simulations, particularly for complex phenomena like subsurface scattering, specular inter-reflections, and global illumination, often employing neural networks, differentiable rendering techniques, and novel algorithms like factorized inverse path tracing. These advancements have significant implications for computer graphics, 3D reconstruction, and related fields by enabling more realistic rendering, improved 3D scanning under challenging lighting conditions, and more accurate material estimation.
