ESR01 – Predictive Rendering of Fluorescent Materials

Charles University, Prague, Czech Republic

Topic Description

The ESR 01 PhD position within PRIME is about developing efficient light transport simulation algorithms for volumetric materials used in 3D printing, and about the inclusion of fluorescence in modern rendering technology. The optical effect of fluorescence is currently neglected in most rendering software, but it plays a significant role in the appearance of certain materials. The research undertaken by this ESR will be both fundamental research about inclusion of fluorescence in modern rendering technology, as well as work with appearance measurement, and the trialling of such rendering capabilities in actual industrial workflows.

Employment Details

Pay is standardised by the EU, and is ample by local standards. 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.

About the research group

The Computer Graphics Group (CGG) at the Faculty of Mathematics and Physics of Charles University in Prague, Czech Republic is led by Alexander Wilkie and Elena Šikudová, and currently hosts seven PhD students and one PostDoc. The team is very international (British, Slovak, Czech, German, Iranian) and uses English as its working language. Topic-wise, the group’s interests are spread across realistic image synthesis, appearance fabrication, sky models, and computer vision. We are proud of our closely knit team environment, and our far-reaching network of collaborators in academia and industry. We are also privileged to be housed in a magnificent historical building right underneath Castle Hill in the historical centre of Prague.
