+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
