Early Stage Researcher PhD - #04
The ESR 04 PhD position is about developing robust error bounds for light transport algorithms. Sophisticated light transport algorithms are used throughout product design, architectural rendering, and movie production. Often the quality of the final image depends simply on the presence of noise in the image. With the increasing use of deep learning for denoising there is less understanding of the actual error in the final image. Simple algorithms such as path tracing support stochastic error bounds by analysing the variance in the image, but bidirectional methods such as photon mapping and path tracing in combination do not have a metric developed that enables computing error bounds. The goal of this task is to develop error bounds for state of the art light transport algorithms and if necessary modify these algorithms to support robust error bounds. Having error bounds will facilitate accurate predictions of lighting in architecture and product design. Understanding the error properties of advanced light transport algorithms will also help to guide future refinements of these algorithms for the purpose of faster convergence.
Pay is standardised by the EU, and allows for comfortable living as a student by local standards. Living allowance is approximately 4400 EUR/month with Family allowance and Mobility allowance to cover cost of moving. Taxes apply, which would normally be in the range 37-40%. Employment duration within PRIME is 36 months, and the start date can be anytime between October 1st, 2020, and September 30th, 2021. However, we prefer candidates to be available as soon as is practical: ideally, we would like to hire until March 2021 at the very latest.
Luxion is a research-driven company. At its core, Luxion brings innovations in computer graphics and related fields to users in industrial design, marketing, and engineering through a fast and easy to use software application. We are a leading developer of advanced 3D rendering, animation, and lighting technology with expert knowledge in areas related to daylighting (atmospheric scattering), light scattering by materials (BRDF and BSSRDF models), light transport algorithms such as photon mapping, and real-time rendering technology.
KeyShot is the first real-time ray tracing application that uses a physically correct render engine based on scientific research in the areas of scientifically accurate material representation and global illumination. Luxion ApS office is located in Aarhus, Denmark. The candidate will benefit from Luxion’s expertise with VR including having access to state of the art VR equipment. In addition, Luxion has developed a VR application based on classic rasterization techniques that provide guidance for the goals of VR in general. This project will benefit from Dr. Jensen, who has been working on advanced light transport algorithms for more than 30 years. The academic supervisor will be Dr. Frisvad at DTU, Copenhagen. As such the candidate should expect to also spend time in Copenhagen and travel back and forth accordingly.
