Joint project for performance enhancement of global illumination (GI) in realtime is initially presented at GTC 2014

RTT, leading provider of high-end 3D visualization solutions, and its customer PSA Peugeot Citroën join forces with technology partners to reach a better performance for realtime Global Illumination (GI). Through deployment within a High Performance Cluster (HPC) noise free, realtime rendering and presentation in 4K resolution are now possible. RTT developed in close collaboration with PSA Peugeot Citroën and chosen technology partners like Reims University, a realtime full GI showcase with a PSA Peugeot Citroën car as rendering model. Therefore the Romeo supercomputer based in Reims, France, equipped with a GPU Cluster consisting of 260 NVIDIA Tesla K20s drivers was being used. The initial live presentation in realtime is scheduled for March, 26 at GTC 2014 in San José, California.

The digital asset is the PSA Peugeot Citroën show car Onyx with complex exterior and interior geometry for the 3D visualization. This will be loaded into the visualization software RTT DeltaGen, which, in turn, will be rendered and streamed in 4K visual quality via RTT Scale from France to the US through a remote display in order to demonstrate the conductivity of the cluster. Native Infiniband enables the transfer of all knots within a few minutes to the full utilization of the GPU resources.

"Tapping into this feasible ´power-on-demand´ potential allows us to achieve photorealistic results in realtime, as if the physical vehicle was right in front of our design and development team. Under these conditions, Design Studies or Perceived Quality Reviews with live changes of geometry, materials or colors can be visualized instantly and offer a high degree of flexibility, while the decision-making process is condensed to the review session itself", states Benoît Deschamps, Manager Visualization Solutions at PSA Peugeot Citroën.

Key technology institutions collaborated with the initiators PSA Peugeot Citroën and RTT: Reims University, who are ranked 5th of the Green500 list with their Romeo supercomputer and technology provider Mechdyne, enabling the high-quality streaming.

"Physical correctness and photorealism in combination with high speed rendering are nowadays key for product development. In this context, the utilization of HPC, in flexible and scalable ways, is gaining in importance. We have today cutting-edge technology solutions in plan and we are currently working on bringing the next big step to 3D visualization", explains Fabien Bartel, Head of Industry Solutions at RTT.
