Hi there,

Do you have an idea what cause and how to fix the problem?

Thank you, tj

https://answers.unity.com/questions/1437621/how-do-i-solve-vr-openvr-error-openvr-failed-initi.html Check those steps. You can also find the last line that says the line number and google the error too. It only works on Windows. It must have steam and steam vr running possibly steam vr has to be in beta mode ( see the link)

also, what are you trying to do with this script?

Hi, Thank you for reply.

also, what are you trying to do with this script?

Please look here https://github.com/EpistasisLab/3DHeatmap Above project is a VR for data visualization. And in shortcut I'm trying to check if it is possible to do data visualization vr with blender.

it must be vr in server-client mode. big data can be accessed only on server. must be accesed from all over the world.

why is that? because data files can't be moved from server to client and typical usage examle is : parse 50GB file, process data/do some calculation, construc dynamic mesh which represents the data, show it and more on 3d scene.

So, I think best idea is to stream camera view from server to client. client can sent coordinates which are request for camera location and rotation. also requests which data and how to visualize. Server based on requests processes data and builds 3d scene and of course sends stream from camera view to client.

that's going to have some serious lag unless you have caching - it may be better to get "proxies" - such as bounding boxes to look at, then when you're ready press a button to load that image from the server at that pitch/lat/lon/yaw - otherwise it's not going to be the best experience. How's progress on checking to see if it works with openvr and such?

I can programming + I know nothing about VR + I know nothing about blender = no progress for now. I will let you know when I find something. Thank you, tj
