VR viewer

Hi all,

I'm very new to the whole VR headset thing. I'm trying to have a workflow where I render in V-ray and present the images on the Meta Quest 3 headset.

From V-Ray I can export either VR cube map or VR Spherical Panorama. But in which app can I view them on the MQ 3?

Thanks in advance!

Maarten

I've not tried it myself but Dj_DooM3 has a video on how to view stereoscopic cube maps: https://www.youtube.com/watch?v=HPZNZs7MC9o

An alternative, if you're comfortable using Unity, would be to code your own app.

Thanks for your reply. I will try the Dj_DooM3 video.

But I am amazed that there is no easy ready to go option for this! 

I work on complex models in sketchup/cinema 4d so I can't use the sketchup viewer on the headset as that can't handle the large models I work on. So an alternative would be to render them out using V-Ray. But as it turns out there is no viewer to display these?!

What do  interior designers/real estate people/retail designers use to display their work in a vr environment? Surely there must be a huge demand for this quite basic functionality?

 

Thanks for the help!

I'm no expert in these industries but my understanding is that real estate agents' VR apps have often just been 360 video tours with clickable hotspots to travel between different video clips for different sections of the apartment or house. 

Architecture firms use a more high end solution that leverage NVIDIA's Omniverse and CloudXR protocol to stream from CAD applications, Unreal or the Omniverse viewer. In the automotive sector, Varjo Reality Cloud is often used to stream directly from VRED.

In essence, you're rendering your complex models on a cloud-based high-end workstation (a virtual machine with crazy powerful GPUs) and only receiving a stream on the more low end headset. Not unlike using AirLink.

You can roll out your own solution if you're good with cloud computing (search for NVIDIA CloudXR) or third party companies like Innoactive have ready to use solutions. It's still pretty early days for this technology and I've not found it great for full VR applications that require low latency, but for visualisations of static models and teleporting around a CAD model, it works well. There are always a lot of demos of this kind of thing at the regular NVIDIA GTC conferences https://www.nvidia.com/gtc/
