generalize selector to pick last Nth rather than very last
adapt getIdFromPick() with .slice() after filter then map on length-N instead of length-1
selector pickers : pickClass and pickId
display result in 3D HUD with rotating objects and selector value
ideally themselves also selectable/usable, e.g clone from HUD to bring back "out"
requires extra work as becoming a child will not work, own positionning
should fix that
could compare to world coordinates instead of "just" position attribute
add a clear selector function to avoid making the HUD unusable
could also pick via volume, e.g wireframe box
start with https://threejs.org/docs/#api/en/math/Box3.containsPoint
can iterate with https://threejs.org/docs/#api/en/math/Box3.containsBox
consider also https://threejs.org/docs/#api/en/math/Box3.intersectsBox
consider pick then apply, i.e changeColorLastId() but for next Id
should be cancealable
