OSX snippet for using GL to transfer full-frame video (without head-tracking) to Oculus Rift via libovr

gistfile1.cpp

uint8_t* EyeBuffer[2]; // raw per-eye data; 

void onIdle() {

    HmdFrameTiming = ovrHmd_BeginFrame(Hmd, 0);

    // ...normal frame management from OculusWorldDemoApp::OnIdle goes here..
    
    // ...and then immediately before you EndFrame:
    // just transfer directly onto the eye textures
    // The texture we're going to render to.

    GLuint texId;

    for (int i = 0; i < 2; i++) {
        texId = ((ovrGLTextureData&)(EyeTexture[i])).TexId;

        glBindTexture(GL_TEXTURE_2D, texId);
    
        // Upload the current texture from EyeBuffer
        glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA,
                     EyeTexture[i].Header.TextureSize.w,
                     EyeTexture[i].Header.TextureSize.h,
                     0, GL_RGBA, GL_UNSIGNED_BYTE, EyeBuffer[i]);

        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
    }

    ovrHmd_EndFrame(Hmd, EyeRenderPose, EyeTexture);
    
}
