Couldn't see the scene

[chen1325-star]

Hi,

I directly launched the GaussianSplattingVRViewer.exe, and this is what I could see. I have already connected to a Quest 2 and make sure my device follows the requirements. Is there any limitation for the openxr version?

Thanks

do you see anything in your headset ?
It seem it's like you have not connected your headset to your computer via link or airlink.
If it's properly connected you can see the Oculus Home:

Now the second problem can be that that Oculus is not your default OpenXR environment.

Hi, I think I setup the headset correctly, v1.1 works smoothly but I couldn't see anything using v1.2

Hi, @chen1325-star I have the same problem. Did you solve it?
Also I want to ask about build config. Did you built it on android or windows platform? and in player settings did you choose in the XR Plug-In management OpenXR or Oculus in the corresponding platform?

In your screenshot, i can see that a file named "point_cloud.ply" should be near the executable file "GaussianSplattingVRViewer.exe". If you remove this file and any other "*.ply" file near the executable does you can see the "default.ply" in VR ?

If it's the case, your point_cloud.ply file should be corrupted, scaled or translated somewhere you cannot see it. can you send it to me that i check it ?

Also is you ply file a file with degree 3 shs ?
This project only work with this kind of gaussian ply file.

To check that you can open the ply file with a text editor and check the header. it should contains 44 f_rest parameters if you have less it's probably not a degree 3 shs file and it will not work.
