I am using cesium on a touch screen device, and the zoom experience is lacking. The user is required to drag with both hands, because a one-handed gesture doesn’t zoom the map nearly enough. Is there any way to increase the touch screen zoom amount (preferably by a multiplier like 4x or 5x)? I couldn’t find anything in the camera API…
We are aware of this behavior and are tracking this in an issue https://github.com/AnalyticalGraphicsInc/cesium/issues/4363. If you have any input, please comment on that issue.
