Oculus Rendering seems off, what is wrong?

Hi,

I've written a sample application with SDKL, OpenGL and SDK 0.3.2 (https://github.com/gaultier/SDL2_OpenGL3.3_Sample). Simple scene, just a cube on a plane and a texture in the background.

My rendering seems weird though (see file attached).

When I put the Oculus on, both images don't quite match up.
Someone told me I might be rendering the eyes inverted (ie right eye on left eye part and vice versa).

Can you tell me what's wrong?

Here's my rendering loop (simplified):

void Oculus::render(Scene * scene)
{
  scene_ = scene;

  computeSizes();
  setCfg();

  ovrBool configurationRes = ovrHmd_ConfigureRendering(hmd_, &cfg_.Config, distortionCaps_, eyeFov_, eyeRenderDesc_);
  //Cannot configure OVR rendering
  assert(configurationRes);

  glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, 0);
  glBindBuffer(GL_ARRAY_BUFFER, 0);
  glUseProgram(0);


  setEyeTexture();

  frameTiming_ = ovrHmd_BeginFrame(hmd_, 0);

  // Bind the FBO...
  glBindFramebuffer(GL_FRAMEBUFFER, FBOId_);
  // Clear...
  glClearColor(1, 1, 1, 1);
  glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

  for (int eyeIndex =0; eyeIndex < ovrEye_Count ; eyeIndex++)
  {
    ovrEyeType eye = hmdDesc_.EyeRenderOrder[eyeIndex];
    ovrPosef eyePose = ovrHmd_BeginEyeRender(hmd_, eye);

    glViewport(eyeTexture_[eye].OGL.Header.RenderViewport.Pos.x,
            eyeTexture_[eye].OGL.Header.RenderViewport.Pos.y,
            eyeTexture_[eye].OGL.Header.RenderViewport.Size.w,
            eyeTexture_[eye].OGL.Header.RenderViewport.Size.h
            );

    // Get Projection and ModelView matrici from the device...
    OVR::Matrix4f projection = ovrMatrix4f_Projection(eyeRenderDesc_[eye].Fov, 0.3f, 100.0f, false);
    OVR::Quatf orientation = OVR::Quatf(eyePose.Orientation);
    OVR::Matrix4f modelView = OVR::Matrix4f(orientation.Inverted());

    // Pass matrici on to OpenGL...
    glMatrixMode(GL_PROJECTION);
    glLoadIdentity();
    glMultMatrixf(&(projection.Transposed().M[0][0]));
    glMatrixMode(GL_MODELVIEW);
    glLoadIdentity();
    // Translate for specific eye based on IPD...
    glTranslatef(eyeRenderDesc_[eye].ViewAdjust.x,
      eyeRenderDesc_[eye].ViewAdjust.y,
      eyeRenderDesc_[eye].ViewAdjust.z);
    // Multiply with orientation retrieved from sensor...
    glMultMatrixf(&(modelView.Transposed().M[0][0]));

    scene_->render();


    ovrHmd_EndEyeRender(hmd_, eye, eyePose, &eyeTexture_[eye].Texture);
  }

  ovrHmd_EndFrame(hmd_);
}

I'm sure the mistake is obvious but I don't see it.

Thanks for your help.
