    Is there a way to keep featurePoints from dying when they go off screen? When panning they seem to be cleared.

    Also, is there a way to adjust the sensitivity and amount of feature points provided, or is this handled completely by ARkit/ARcore?

    What's your purpose for keeping them alive outside of the screen?

    I'm using planes primarily and featurePoints secondarily for tracking. For featurePoints, the pose is estimated using the available featurePoints near the touch position. Everything is fine with constant movement, but when you hold still and just rotate the device, there's hardly ever enough parallax for a sufficient amount of new featurePoints to be picked up. By using the old featurePoints the user could pan and move object simultaneously. Once new (more accurate) featurePoints are found, the older featurePoints can be discarded.
