DOI: 10.1109/tci.2020.2964246
Abstract: The light transport captures a scene's visual complexity. Acquiring light transport for dynamic scenes is difficult, since any change in viewpoint, materials, illumination or geometry also varies the transport. One strategy to capture dynamic light… read more here.

DOI: 10.1111/cgf.13936
Abstract: Layered materials capture subtle, realistic reflection behaviors that traditional single‐layer models lack. Much of this is due to the complex subsurface light transport at the interfaces of – and in the media between – layers.… read more here.

DOI: 10.1117/1.jbo.25.2.025001
Abstract: Abstract. Significance: Monte Carlo (MC) light transport simulations are most often performed in regularly spaced three-dimensional voxels, a type of data representation that naturally struggles to represent boundary surfaces with curvature and oblique angles. Not… read more here.
