Matrices

vr::HmdMatrix43_t mat = m_pHMD->GetEyeToHeadTransform( nEye );

##Events vr::VREvent_t event; while( m_pHMD->PollNextEvent( &event, sizeof( event ) ) ) { ProcessVREvent( event ); }

##Controllers for( vr::TrackedDeviceIndex_t unDevice = 0; unDevice < vr::k_unMaxTrackedDeviceCount; unDevice++ ) { vr::VRControllerState_t state; if( m_pHMD->GetControllerState( unDevice, &state ) ) { m_rbShowTrackedDevice[ unDevice ] = state.ulButtonPressed == 0; } }

##Composition
