Real time 3D object remote rendering in 5G

Tested systems

TMIT VKE4

HW: Virtual machine with NVIDIA Tesla V100 GPU used as a vGPU

OS: Windows Server 2022

Software:

• NVIDIA CloudXR SDK (4.0)
• NVIDIA Graphics Driver (451.48_grid_win10_server2016_server2019_64bit_international)
• Steam and SteamVR (latest, not required for CloudXRServerSample.exe)

Desktop computer

HW: NVIDIA GeForce RTX 3050

OS: Windows 11

Software:

• NVIDIA CloudXR SDK (4.0.1)
• NVIDIA Graphics Driver (32.0.15.6094)
  • This is the default driver, that was installed through Windows Update, no other configuration was needed
• Steam and SteamVR

I want to thank Simonyi Károly Collegium for providing this extra hardware for testing.

Usage

• Replace the .obj file in C:\Program Files\NVIDIA Corporation\CloudXR\VRDriver\CloudXRRemoteHMD\bin\win64\assets\models\ with your model of choice. (In 4.0 this is lucy.obj and in 4.0.1 this is ship_large.obj)
  • Alternatively you can symlink the new .obj by executing New-Item -Path .\ship_large.obj -ItemType SymbolicLink -Value .\exported.obj
• Start C:\Program Files\NVIDIA Corporation\CloudXR\VRDriver\CloudXRRemoteHMD\bin\win64\CloudXRServerSample.exe.
• Connect the client to the server.

Tested models

All files in the models folder are either from CloudXR SDK or Poly Haven, licensed under CC0 1.0. To view a copy of this license, visit https://creativecommons.org/publicdomain/zero/1.0/

Models from Poly Haven should be downloaded as .blend files, you can export them to .obj files using Blender. You can also make more complex models using these models and export them into one .obj file.

Statistics are from Blender.
