Pointeract

Appearance

Wheel Pan Zoom Module ​

This module monitors wheel events, resolves them and emits pan/zoom events. It supports touchpad gestures and different control schemas, and is able to automatically change the control schema based on the user's behavior.

Events: pan zoom

Control Schemas ​

Normal Control Schema: uses the mouse wheel to zoom.

Professional Control Schema:

  • Zoom: mouse wheel + ctrl key
  • Pan Horizontally: mouse wheel + shift key
  • Pan Vertically: mouse wheel

INFO

Most devices with touchpad interpret touchpad gestures as mouse wheel + key press. So professional control schema enables critical touchpad support.
