Global Illumination - Solved Problem or Challenge?
Physically-based light transport simulation is an essential component of rendering photorealistic images and has a wide-range of applications, e.g. in movies, games, but also in engineering and visualization. After roughly three decades of research we can retrospect on major progress, but are still left with deficits in existing approaches. Light transport is an inherently complex, but also parallel(izable) problem - will advances in hardware eventually solve it for us? An introduction to the topic followed by an overview of different approaches and technical aspects will allow us to examine this question and - to anticipate the answer - develop understanding for unsolved issues.

Carsten Dachsbacher is Full Professor at the Karlsruhe Institute of Technology. Prior to joining KIT, he has been Assistant Professor at the Visualization Research Center (VISUS) of the University of Stuttgart, Germany, and post-doctoral fellow at REVES/INRIA Sophia-Antipolis, France. He received a MSc/diploma degree in Computer Science from the University of Erlangen-Nuremberg, Germany, in 2002 and a PhD in Computer Science in 2006. His research focuses on real-time computer graphics, interactive global illumination, and perceptual rendering, on which he published several articles at various conferences and journals including SIGGRAPH, I3D, EG, EGSR. He has been a tutorial speaker at Eurographics and the Game Developers Conference and reviewer for various conferences and journals.

DIVA Lecture by Jacopo Pantaleoni, NVidia
Remapping Graphics on the Graphics Processors
This talk will take a look at recent work made to remap general purpose graphics on the GPU, a parallel processor originally designed to execute a specific fixed-function graphics pipeline. It will show-case examples ranging from modern parallel algorithms for spatial indexing of geometric primitives to the efficient execution of software rasterization pipelines, while highlighting the careful balancing acts needed to remap complex algorithms to modern massive multithreading architectures.

Jacopo Pantaleoni is a Senior Architect at NVIDIA Research, where he has been studying new stochastic methods for physically based light transport simulations, developing novel rendering techniques for the film visual effects industry (contributing key technology - the PantaRay engine - for the Oscar winning special effects in Avatar), providing new algorithms for real time ray tracing and rasterization, and studying the feasibility of complex, programmable software pipelines on massively parallel processors.
