• Guiding the product plan of the Group – Reducing the time of the design cycle and unit costs (MCP)
• Rapid delivery of vehicle innovations,
• Reactivity to market demand,
• Supporting the increase in the vehicle product plan,
• Guaranteeing our competitiveness.
– Guaranteeing quality : design to deliver “good” • Requirement with regard to the competition and to the growth in volumes,
• Having processes that guarantee quality and being able to measure it.
– Working in the Extended Enterprise • Access for suppliers to our systems from outside,
• The same for our partners in Europe, Asia ….
• The Technico-Industrial Upstream assists the Group’s product plan with high-performance tools, such as digital factory and virtual reality.

No compromises : RTT Scale For What
• Scale with clusters in order to render complex scenes at high speed with high-end quality
• Allows high-resolution output on multi-segment Powerwalls
For Whom
• Engineers & designers
• Accelerated process through distributed realtime renderings
• Highly flexible – scalability for single and multiple display setups
March 26, 2014 | San Jose, CA
• Enable high-end graphics mobility and asset rationalization
• Focused on high-end requirements
– Viz-friendly:
• Minimal image quality loss
• Minimal latency
• Minimal sender machine performance impact
– Viz-center friendly: 4k and above, stereo3d, multi-GPU
• Based on OEM technology from Scalable Graphics

Use case : Digital Project Review
• For virtual reality , we use : • OpenGL rendering with precomputed lightmap.
• Stereo, tracking, multi display.
• For fixed point of view, we can use raytracing or global illumination after few seconds.
• For styling use cases, we use : • Realtime Raytracing and Ambient Occlusion or precomputed lightmap.
• For fixed point of view, we can use global illumination after few seconds
• 1 Computer with one Nvidia K 6000 is enough for 2K, limited framerate on 4K resolution
• For perceived quality review, we use : • Interactive global Illumination or offline rendering with GI.
• 1 or 2 Computers with multi GPU but is not enough for realtime global illumination.

Use case : Digital Project Review
The aim is to challenge the physical mockup.
• To do that, we need:
• Real time rendering.
• Physical Renderer approach.
• Physical inputs, ex :Material measurement, …
• Real point of view.
• High resolution.
The solution is to combine virtual reality + Styling + perceived quality setting ….
Could we take decision on approximate renderer ? No, but a renderer with physical approach is the way.
Could you do that with 1 or 2 computers ? No, but HPC with GPU & renderer based on GPU are the solution
We must buy a HPC by user ! No, but an efficient remote graphics is the way to access to this power.
