• 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


• 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


A word on performance • Multiple influencers

• Today’s demo: 1920x1080@60Hz : 250Mpixels/s at 20Mb/s (WAN), 160+70 ms latency

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.
