Abstract:

After a quick overview of my professional carrer, I will present some of recent research works I was involved in. Physically based rendering offers a tremedous visual quality, but misses artistic control needed for story telling. Skilled graphists tend to break the production workflow to have artistic freedom. We explore how to give artistic directed tools to efficiently control computer generated images in a physically based context. I will present the Ray Portal[1] and Global illumination shadow layers [2]. Next I will focus on the color content editing and present our work on constrained palette space exploration [3] as well as trending research direction I am focused on.

Short Bio:

David Vanderhaeghe is an Associate Professor at IRIT-Université de Toulouse where he started in 2010. He completed his Ph. D. in 2008 at Université de Grenoble-INRIA Rhône-Alpes under the supervision of Joëlle Thollot and François X. Sillion. Then he spent two years as a Postdoctoral Researcher at LaBRI-INRIA Bordeaux Sud-Ouest/Université Bordeaux 1. His research focus on image synthesis, rendering, stylization and user control for image and animation creation. He has participated to several program comittee (Eurographics short paper, Expressive, WSCG...) and is a regular reviewer for major journals and international conferences (ACM Siggraph TOG, Eurographics, IEEE-TVCG, CGF). He is co-head of the computer graphics and image analysis master program of Université de Toulouse, France. He was also invovled in national animation of the research as a comittee member of the french association for computer graphics (AFIG) and the national research agency lab on computer graphics and virtual reality CNRS GRD IG RV, as well as the lead of the working group on rendering. He is currently involve in IRIT laboratory concil.
