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!

``C++ 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.
