Hi @aheany, don't worry for the delay.
Here are both header and source from my application, beside a few logging headers and the xr_linear.h header from the OpenXR-SDK, it should be fairly self contained.
mesh_detector.zip (2.9 KB)
As for frame loop, I update the mesh detector between xrWaitFrame and xrBeginFrame only if XrFrameState::shouldRender is XR_TRUE and the session state is either XR_SESSION_STATE_VISIBLE or XR_SESSION_STATE_FOCUSED.
I though about moving the mesh_detector in its own thread but haven't done it yet.
Yes I'm refering to the MLMeshing C api, which I also tried in parallel (exclusively), you can see the issues I found with it here. I can also share the code if you'd like.
