H/C config for sensor stereo views

[Lales.Charles]

Hi,

We would like to setup an H/W config to generate sensor stereo views, left / right eye, each view at 1600 x 1200 resolution.
We need to pick one or two Quadro GC, more or less expensive, because of external sync based on Quadro Sync II.

Question: to render these 2 views, what would be suitable..

• 2 instances of Unigine engine with 2 camera positions.. right? or is there another way?
• 2 x RTX4000 or 1 x RTX6000?

Thanks in advance.
Kind regards,
Charles

In general it's better to use one more powerful GPU on one PC. So I'd say go for the 1x RTX 6000

May I ask you how what will be like your final build? And what kind of stereo sensor imitaion you're working on?

Thanks.

Ok, noticed.

Is it fine with 2 x 1600 x 1200 resolution?
Is it right 2 instances of engines with 2 cameras or is there another possibility?

Regarding sensor, you have kind of idea on this other post:

Regarding pipeline:
Unigine generated stereo view box1 (syncII) +  another box2 (syncII) > blending box3 > worping + symbology box4 (syncII) > HMSD
with feedback loop HMSD > box1,2,4
... maybe a diagram could be helpful.

Kind regards,
Charles

I'm sorry, but this raised even more question for me :)

1. First of all, I'd like to ask why do you want to generate a stereo image on two engine instances? Is it HMD specific?
2. What are the boxes?
3. The most mysterious term for me is symbology box4. Could you please explain what is it?

Best regards,

Hi,

The different box are H/W related, material sometimes by external providers.
Symbology consists of all info overlay.

Regarding the IG starting point, with Unigine, we need to get 2 output of 1600 x 1200, one per eye.
What would you suggest then? One engine instance running with one RTX6000..?
Sorry for basic question, but then how to address different camera or view port to different GC output with expected resolution..?

Kind regards,
Charles

I'm confused with the requirement for stereo rendering. We support it out-of-the-box, but maybe I don't fully understand your need.

I remember you were building a prototype with HTC Vive. Is this task similar to what you're doing now? We have OpenVR support with AppOculus and AppVive and built-in stereo with render_stereo command (also can be turned on in the UnigineEditor).

Here's the article that describes stereo in UNIGINE: https://developer.unigine.com/en/docs/2.7.3/principles/render/output/stereo/

Please, let me know if I misunderstood you.

Hi,

Yes we have some project VR oriented with HTC Vive, but this another one is more multi screen oriented, with here a complex IG chain including different HW in the loop as described previously. FYI UNGINE is aimed to be used for several different activities in our company. This explain why we're motivated as well to setup a clean / efficient collaborative strategy.

Thanks for link, I guess we have to check out these 2 options:
- Separate Images
- Quad Buffered Stereo
We have the need to use 2 dedicated CG output and set resolution 1600 x 1200 for each.
Additional suggestion welcome ;)

Kind regards,
Charles
