ofxOpenVrUtil

openFrameworks addon for bridging OpenVR, a refactored version of perevalovds/ofxOpenVR.

OpenVR is a cross-platform open source API to access VR system through SteamVR (by ValveSoftware). Main support target is HTC VIVE (I was using VIVE PRO for developping/debugging) but it might be compatible to Oculus Rift S, Valve Index or other VR hardwares which can play SteamVR for just displaying a scene. But for major hardware vendors, such like Oculus(facebook) and HTC published native SDK which are supposed to run faster than via OpenVR.

Feature

• Rendering controllers (mesh + texture)

• Simple interface: just submit texture to show in HMD!

  class ofApp : public ofBaseApp {
  public:
      ofxOpenVrUtil::Interface vr;
      // ...
  
      void setup() {
          vr.setup();
      }
      void update() {
          vr.update(); // update device orientations
  
          // ... update your textures for both eyes
  
          // submit textures to VR!
          vr.submit(tex_l, vr::Eye_Left);
          vr.submit(tex_r, vr::Eye_Right);
      }
      void exit() {
          vr.close();
      }
  }
  

• VIVE Only: Stencil Mesh (Hidden Area Mesh) to avoid pixels to be rendererd. (17% faster)

• VIVE PRO Only: See-through from stereo-camera on HMD

• Controller inputs as ofEvents

• Gizmo UI in VR

• Vive trackers

• Run without HMD (see an example)

Setup

• OpenVR is a submodule of this repo, so we have to git submodule

  > cd of\addon
  > git clone https://github.com/nama-gatsuo/ofxOpenVrUtil
  > git submodule init
  > git submodule update
  
  

• You can then use the OF Project Generator to generate projects with the appropriate headers and libraries included.
