Computer Science
ACM Trans. Graph.
11 November 2016

We propose a practical foveated rendering system that reduces number of shades by up to 70% and allows coarsened shading up to 30° closer to the fovea than Guenter et al. Expand

Particle‐Based Simulation of Fluids

Simon Premoze, T. Tasdizen, J. Bigler, A. Lefohn, R. Whitaker
Computer Science
Comput. Graph. Forum
1 September 2003

Due to our familiarity with how fluids move and interact, as well as their complexity, plausible animation of fluidsremains a challenging problem. We present a particle interaction method for… Expand

Interactive reconstruction of Monte Carlo image sequences using a recurrent denoising autoencoder

Chakravarty R. Alla Chaitanya, Anton Kaplanyan, +4 authors Timo Aila

We describe a machine learning technique for reconstructing image sequences rendered using Monte Carlo methods. Expand

Adaptive transparency

M. Salvi, J. Montgomery, A. Lefohn
Computer Science
HPG '11
5 August 2011

Adaptive transparency is a new solution to order-independent transparency that closely approximates the ground-truth results obtained with A-buffer compositing but, like a Z-buffer, operates in bounded memory and exhibits consistent performance. Expand

An Ocularist's Approach to Human Iris Synthesis

A. Lefohn, Brian Budge, P. Shirley, R. Caruso, E. Reinhard
Computer Science
IEEE Computer Graphics and Applications
1 November 2003

We present an approach that enables users other than trained ocularists to create a realistic looking human eye, paying particular attention to the iris by layering semitransparent textures. Expand
