How do I integrate SRWorks SDK to another OpenVR projects?

[bluekyu]

Hello. I am developing a SRWorks sample in my C++ project (using open source engine).

 

The project is already using OpenVR SDK, but integration of SRWorks SDK does not works well.

(Note that, Unreal sample and C API samples work well)

 

I tried some codes, but failed:

1. Pre-init SRWorks: Crash in ViveSR_API.dll when creating a new window in the engine.

2. Post-init SRWorks after OpenVR init

   1) Set VR_INIT to true OR false for ID_SEETHROUGH: Crash by GL context

   2) Use "SeeThrough::InitType::BACKGROUND": Crash by GL context

   3) Threading for SRWorks parts: Rendering works, but VR submit does not work

 

Is there right usage when SRWorks is used with OpenVR?

Hi bluekyu,

 

did you set InitType of SEETHROUGH module BACKGROUND?

[bluekyu]

Yes. I tried to use below codes for SeeThrough module:

 

ViveSR_SetParameterBool(ID_SEETHROUGH, ViveSR::SeeThrough::Param::VR_INIT, true);ViveSR_SetParameterInt(ID_SEETHROUGH, ViveSR::SeeThrough::Param::VR_INIT_TYPE, ViveSR::SeeThrough::InitType::BACKGROUND);

 

Also, I did it in non-thread and multi-thread cases.

In non-thread (main thread), it caused crash on my GL draw call.

 

In multi-thread, crash does not happen, but HMD rendering becomes off (HMD shows black display and SteamVR does not show my application name.)

 

And I attached SRWorks log using SRLOG_LEVEL_MAX in non-thread.

(I created only ENGINE_SEETHROUGH module and did not start it.)

Are you using OpenGL in your existing code?

Seems SRWorks having conflict with other GL initialization due to it works with hellovr_dx12 sample in OpenVR SDK but failed with hellovr_opengl sample. 

[bluekyu]

Yes, I am using OpenGL for rendering.

So, if SRWorks is initialized using multi-thread, the crash does not happen.

But OpenVR rendering (submitting texture) does not work.

[Daniel_Y]

which version of SRWorks you are using?

[bluekyu]

I used version 0.7.5 and downloaded it at June 11.

[liyi_zheng]

Hi bluekyu,

 

Please replace those two dlls(DualCameraInterface and ViveSR_SystemMonitor) with workable attaced files of version 0.7.5.1.

 

Thank you

[bluekyu]

Thank you! First of all, I just ran my project with those.

The crash did not happen and VR rendering worked well!

 

I will test SeeThrough and Depth module and will close this discussion if a issue does not exist.

 

Thanks.
