Virtual Wave Optics for Non-Line-of-Sight Imaging
Xiaochun Liu, Ibón Guillén, Marco La Manna +6
Non-Line-of-Sight (NLOS) imaging allows to observe objects partially or fully occluded from direct view, by analyzing indirect diffuse reflections off a secondary, relay surface. D…

Progressive Transient Photon Beams
Julio Marco, Ibón Guillén, Wojciech Jarosz +2
In this work we introduce a novel algorithm for transient rendering in participating media. Our method is consistent, robust, and is able to generate animations of time-resolved li…

Area-preserving parameterizations for spherical ellipses
Ibón Guillén, Carlos Ureña, Alan King +4
We present new methods for uniformly sampling the solid angle subtended by a disk. To achieve this, we devise two novel area-preserving mappings from the unit square to a…
