Geom-e-Tree Gesture Reference

Here are the basic definitions to go with the chart:
  • Panning - is putting one finger down on the display, and then moving it, and finally lifting it to end your gesture.
  • Tapping - is tapping one finger once on the display.
  • Double Tapping - is tapping one finger twice in about the same time you'd say tap tap.
  • Pinching/Spreading - These gestures are two sides of the same coin, one having the opposite effect of the other. Two fingers (typically your thumb and index finger) must touch the display to start the gesture. Then you can move your fingers together or spread them apart. In the same gesture you can spread open for a while then pinch then change back to spreading again all without lifting your fingers off the display. You can use one finger from each hand, and start them further apart for finer control.
  • A Two Finger Tap - is tapping two fingers (simultaneously) once on the display.

Experiment!

ONE FINGER GESTURES
Change.. Gesture
increase angle
open the tree up 		pan down with one finger
decrease angle
close the tree up 		pan up with one finger
bump angle +1° (eg. 45° → 46°) tap lower half of display.
bump angle -1° (eg. 45° → 44°) tap upper half of display.
The Perfect Common Ratio Mode
Toggle it on/off. 		double tap anywhere on the display.
TWO FINGER GESTURES
Change.. Gesture
increase common ratio
makes branch lengths relatively shorter from level to level. 		Two fingers spreading apart.
Tip: For fine adjustments, start with fingers further apart.
decrease common ratio
makes branch lengths relatively longer from level to level. 		Two fingers pinching together.
Tip: For fine adjustments, start with fingers further apart.
Add a branch
(decrease branching factor) 		two-finger tap in upper half of display
Remove a branch
(decrease branching factor) 		two-finger tap in lower half of display
