OWL for VR

[bipul-mohanto]

Hello!

As you may agree, real-time ray tracing and VR are the best fit to level up immersion (under some constraints). As this is an active research domain, I am also interested in exploring. But, at this moment, I have a few queries if you could give me some directions:

1. Is it possible to work on VR with OWL?
2. If I want to extend the sample codes (e.g., Ingo Wald's optix7course) to VR (Vive Pro Eye), which API/SDK should I use to communicate between OWL and VR?
3. Should I use OpenVR (deprecated), or OpenXR?
4. NVIDIA VRWorks SDK seems a good fit also, it has already included some amazing features, e.g., Variable Rate Shading, DLSS. However, the documentation says the SDK is based on Maxwell and Pascal GPU architecture, not on Turing. So will it work on RTX Turing?
5. The sample codes come with VRWorks are DX11/VK12/VK11/VK12/OGL. No OptiX/OWL sample of course.
6. I found in GTC, developer from STARVR saying OpenXR would not be optimized for high end graphics (I assume ray-traced scene is high end), VRWorks would better optimized - but I am not sure VRWorks would support ray-tracing.

I would request you to give some guidelines on how to work on ray-tracing-VR-OWL-OptiX.

After searching a bit, I found some of the answers (but not all), please correct me if I am wrong:

1. --
2. --
3. OpenXR is better (and may be the only one) option than OpenVR
4. VRWorks SDK has designed for raster pipeline only. It will work any latest architecture, eg. turing, ampre.
5. VRWorks works for DX11/VK12/VK11/VK12/OGL, if use OWL-OptiX-CUDA, probably data need to introp to any of the APIs that has been included to it already. Although I am not sure how it would work.
