openxr-vulkan-example's Issues

Have you set this up to support any kind of batched "single pass rendering"?

Hey, nice project. Can you pls elaborate a little bit on how you render the geometry? Do you use the classic old multipass way of one swapchain per eye and render all geometry twice? Or do you use texture array / image array / target array, and batch-render each object to both indexes? Or do you use a double-wide swapchain with both eyes, with two different imageRects? 🙂🙃

I'm new to openxr sdk, and am searching around for the sake of my sanity and reference/verification, if there are any boilerplates out there that have actually done some kind of single pass rendering with openxr. (nothing comes up in search beyond unity and unreal)

Exception while acquiring new image from swapchain

The exception occurs while acquiring new image from swapchain, it doesn't occur on oculus quest 2, but when I tested it on HTC VIVE PRO it occured

No swapchain image has been acquired

Hello! Thanks for providing this sample, it is the best looking I found so far!

I am trying to run it on Windows 10, MSVC 2022 with a HP Reverb G2 headset. I installed a fresh Vulkan SDK 1.3.283.0.
Now as far as I know my headset doesn't support OpenXR with Vulkan, but with the help of this tool: https://github.com/mbucchia/OpenXR-Vk-D3D12, I managed to run Godot XR samples using the Vulkan renderer (called Forward+). So I assumed this sample should also work with my setup (this assumption can be easily wrong). I made sure to disable my OpenXR Toolkit.

I am getting the following validation errors in Debug, not sure if they are important:

I am confused about the first ones regarding empty usage, because I confirmed ImageBuffer.cpp always assigning a non-zero usage.

The VR app does start up in my headset and keeps running, but I am only getting a black scene. Meanwhile this error is continuously logged:

Exception thrown at 0x00007FFD8167BA99 in openxr-vulkan-example.exe: Microsoft C++ exception: msxr::XrResultException at memory location 0x000000F8974FD890.
ERROR (OpenXR) : [xrReleaseSwapchainImage] No swapchain image has been acquired.

Please let me know if you have any suggestion.

xrGetSystemId: -2

OS: Windows 10
Device: Oculus Quest 2
Runtime: SteamVR
OpenXR version: 1.0.22
OpenXR-SDK-Source version built: 1.0.26 (because, I don't need eye tracking, and Oculus Quest 2 dosn't has it)

Hi.
I create my own application to interact with VR and can you help me with it, pls? When I try to get system id, I get error code -2 (with your app the same behavior).
Maybe, you know how to fix it? Thx, in advance!

Did a clone/build, only got left eye rendering

Hi thanks for doing this projects as I've been trying to get my head around Vulkan/OpenXR as a background thing and this helps a lot.

Anyway I've just done a clone and build using MSVS2019 & latest Vulkan SDK, all I get rendered is the cube in the left eye. The right eye and mirror display are black. I've not started to dig in to why but through you should know.

Also I've got WMR headset so I'm going through StreamVR, M$ will be M$
