Norbert Bus

PhD student in computer science

I have obtained my MSc degree in Mathematics at Budapest University of Technology and Economics. I am in the 3rd year of my PhD at Université Paris-Est which is focused on the application of data structures and algorithms from computational geometry to various problems (mainly in computer graphics). As the end of my PhD is quickly approching, I am searching for a new research oriented position. I am interested in vision problems as well, however I have not worked on them recently.

You can find my CV here.

IlluminationCut

Abstract

We present a novel algorithm, IlluminationCut, for rendering images using the many-lights framework. It handles any light source that can be approximated with virtual point lights (VPLs) as well as highly glossy materials. The algorithm extends the Multidimensional Lightcuts technique by effectively creating an illumination-aware clustering of the product-space of the set of points to be shaded and the set of VPLs. Additionally, the number of visibility queries for each product-space cluster is reduced by using an adaptive sampling technique. Our framework is flexible and achieves around 3-6 times speedup over previous state-of-the-art methods.
