Description

Precomputed Lens Transport Maps is an ACM Transactions on Graphics paper by University of Waterloo authors, hosted on arXiv as a PDF. Precomputed Lens Transport Maps presents a neural, wavelength-aware lens model that maps incident rays to exitant rays with Fresnel throughput and an occlusion classifier for aperture discontinuities. The TOG paper from the University of.

Accurate real-time simulation of lens optics remains challenging due to the computational expense of full ray tracing and the limitations of existing approximations. The commonly used pinhole model and thin-lens model ignore many optical.

It targets advanced researchers and engineers in rendering, vision, or geometry who already work with the problem domain. Authors listed in the submission include Yang Chen, Xiaochun Tong, Afet Abzar, Leo Hanxu, Matthew Avolio, Toshiya Hachisuka.
