PointerOverlay¶
Overview¶
The PointerOverlay shows pointer locations in the scene. This is useful when recording a session for interviews or when a teacher is broadcasting a tablet session on an overhead projector. See https://github.com/phetsims/scenery/issues/111
Each pointer is rendered in a different <svg> so that CSS3 transforms can be used to make performance smooth on iPad.
