How to get raw sensor data of Oculus with the SDK later than v1.3?
I've tried getting raw sensor data (raw acceleration, gyro, magnetometer) of my Oculus DK2 via ovrTrackingState::RawSensorData, which is wrote in the official document of SDK v0.4 to v0.8. But it seems that the section related to raw sensor data doesn't in the document of later version than 1.3. And there is no RawSensorData in ovrTrackingState. So can I get the raw sensor data of an Oculus DK2 or CV1 through the official SDK? Or can I get it from another way?
Multiple Apps Running Without Focus
tl;dr Best way to run a program that accesses head position while a different program is 'in focus'? I am beginning (play nice, I have no VR dev experience yet) VR development on an application for my honours project 'Creating a VR driving simulator and analysing head movement in VR'. My main goal as far as an actual application is a program that tracks head position during a session and stores it in a usable data format. I need to be able to run this program while the user is playing a session of 'City Car Driving'. So the app needs to have realtime access the sdk while it is not in focus, or it needs to be an 'overlay' or 'underlay' to the program that's already running. Is this accomplishable? Or do I need to go about it some other way? Thank you, Otto
Is it possible to disable all tracking?
Hi, I've spend couple days trying to find a way to disable all tracking from the HMD(so extend display mode?), but could not get a working method so far. By all tracking i mean both position and rotation, where position is simple, current SDK provide that toggle directly. I'm using Unity 5.4.0f1 as of today, and testing on both DK2 and CV1. So far I've tried every method I could find via google and forums, nothing seem to work including tricks like "zero out" rotations each frame. Using Unity's build-in camera system does not seem to allow any control of camera at all, and the OVR camera rig does not provide such function directly. I also tried the timewarp methods and it's not/no longer working. For now I'm going to take a deeper look at the camera rig and see if i could come up with something. Researched on this for days and saw all methods were for 0.6 and earlier, or everyone turned to argue about the "uncomfortable experience" by disabling the tracking, which is out of the scope in my situation. For those of whom interested in providing evidence of "uncomfortable experience", I want to achieve this because I'm using external tracking system, which provides better information than the HMD's. Having both the HMD and external tracking system makes the rotation "doubled". I'm not sure if i should post this in Oculus forum or Unity's, so maybe I'd to create a duplication over there later today if it remains unanswered.. Thank you and everyone in advance.sRGB render target issue
I created an sRGB render target + view and my app clearly appears too bright in the HMD. I used: desc.Format = OVR_FORMAT_R8G8B8A8_UNORM_SRGB; desc.MiscFlags = ovrTextureMisc_None; and verified that ovr_CreateTextureSwapChainDX() returns a DXGI_FORMAT_R8G8B8A8_UNORM_SRGB texture. Checking the Tiny Room sample, I was surprised to find that it doesn't follow the guideline from: https://developer.oculus.com/documentation/pcsdk/latest/concepts/dg-render/ and creates a non-sRGB view for the sRGB render target. I am puzzled, can somebody explain what is going on? OculusRoomTiny: main.cpp: bool Init(ovrSession session, int sizeW, int sizeH) { Session = session; ovrTextureSwapChainDesc desc = {}; desc.Type = ovrTexture_2D; desc.ArraySize = 1; desc.Format = OVR_FORMAT_R8G8B8A8_UNORM_SRGB; desc.Width = sizeW; desc.Height = sizeH; desc.MipLevels = 1; desc.SampleCount = 1; desc.MiscFlags = ovrTextureMisc_DX_Typeless; desc.BindFlags = ovrTextureBind_DX_RenderTarget; desc.StaticImage = ovrFalse; ovrResult result = ovr_CreateTextureSwapChainDX(session, DIRECTX.Device, &desc, &TextureChain); if (!OVR_SUCCESS(result)) return false; int textureCount = 0; ovr_GetTextureSwapChainLength(Session, TextureChain, &textureCount); for (int i = 0; i < textureCount; ++i) { ID3D11Texture2D* tex = nullptr; ovr_GetTextureSwapChainBufferDX(Session, TextureChain, i, IID_PPV_ARGS(&tex)); D3D11_RENDER_TARGET_VIEW_DESC rtvd = {}; rtvd.Format = DXGI_FORMAT_R8G8B8A8_UNORM; rtvd.ViewDimension = D3D11_RTV_DIMENSION_TEXTURE2D; ID3D11RenderTargetView* rtv; DIRECTX.Device->CreateRenderTargetView(tex, &rtvd, &rtv); TexRtv.push_back(rtv); tex->Release(); } return true; }
Exception thrown when calling ovr_CreateTextureSwapChainDX
Hello, My name is Johann and I've been using the OVR SDK with DX11 for 4 months now with an Oculus Rift CV1 and everything worked fine (TrackingState OK, rendering in textures OK). Until I switched to a new computer. Both are on Windows10 (the new one is Professional, the old one is Family). The samples (downloaded on the 02/02/2018) compile just fine. However when I launch OculusRoomTiny (DX11) in Debug Win32, Visual Studio (14 2015) breaks on the function ovr_CreateTextureSwapChainDX(). The error is : Exception thrown at 0x74E65F5D in OculusRoomTiny (DX11).exe: 0xC0000005: Access violation reading location 0x00000000. However when I click on "continue", the program runs just fine on the Oculus. Here is the call stack when the violation occurs : > ntdll.dll!_NtProtectVirtualMemory@20 () Unknown KernelBase.dll!VirtualProtect() Unknown LibOVRRT32_1.dll!0f63b5a4() Unknown [Frames below may be incorrect and/or missing, no symbols loaded for LibOVRRT32_1.dll] LibOVRRT32_1.dll!0f63a3bb() Unknown LibOVRRT32_1.dll!0f64f371() Unknown LibOVRRT32_1.dll!ovr_ReleaseHapticsClip() + 2832 bytes Unknown d3d11.dll!NDXGI::CResource::QISurface(void *,struct _GUID const &,void * *,unsigned long) Unknown d3d11.dll!NOutermost::CDevice::CreateLayeredChild() Unknown Here is the full output of the program : 'OculusRoomTiny (DX11).exe' (Win32): Loaded 'C:\Users\jnovak\Downloads\OculusSDK\Samples\OculusRoomTiny\OculusRoomTiny (DX11)\Bin\Windows\Win32\Debug\VS2015\OculusRoomTiny (DX11).exe'.

I have tried to uninstall/reinstall the OculusRift application several times (I was thinking maybe there was a corrupted dll or something) but nothing has changed. I really don't know what I can do to solve this issue. Have one of you ever encountered such a problem ? Thank you, Kind regards, Johann NOVAKDK2 and CV1
Hi all. This is a two part question. Question 1: What is the latest SDK that the DK2 supports. Can it be developed with the newest as of Nov 2017, 1.20.0? Question 2: When developing with the CV1, does Home need to be installed in order for it to work with developer apps? The reasons for the questions is that I am trying to determine which headset to go with to begin development for my own personal apps, no intent on distributing. Preferably I would like to remain offline.ovrSensorData struct removed from SDK 1.3.2?
It appears the ovrSensorData / rawSensorData data have been removed from the 1.3.0 SDK. Now you see them in v0.8.0: https://developer.oculus.com/doc/0.8.0.0-libovr/structovr_tracking_state.html and now you don't in v1.3.0: https://developer.oculus.com/doc/1.3.0-libovr/structovr_tracking_state.html I can't see any mention of that removal in the release notes, but there ya go. Is there an equivalent query in v1.3.2 to examine the HMD sensor data for CV1, or is reading of the Oculus sensor data now blocked?
Assigning custom cameras to the separate displays (scientific research)
Hi guys, the question is rather simple: can I assign my own cameras to the two separate displays of my rift? (Unity x CV1) I've been calibrating my display by spectral measurements (I do scientific research on colour perception) and it seems that there is a large colour difference between the left and right display. I'd like to solve this by rendering different cubemaps (with corrected colours which differ for each display) with two different cameras and sending the feed to the respective displays. Thanks in advance
