third axis: deltaZ / zoom

[xiel]

• normalize pinch to deltaZ

hey @xiel, was this ever implemented / does this package support z axis stuff in general?

e.g. doing const wheelGestures = WheelGestures({ preventWheelAction: "z" }) doesn't seem to prevent pinching to zoom, which I would think it would? Changing to y prevents this behavior, but then of course this also prevents vertical scrolling.

Documentation indicates that z is supported, but this issue suggests otherwise so thought I'd check. Thanks and nice work btw!

Hi @lawderp,

currently the z axis is only supported for mice that emit deltaZ. The pinch gesture is not supported yet.
I'll try to have a look into this during the next weeks.

Cheers

ah ok no worries. If you get it working do let me know!

(more on my use case: I just want to do trackpad pinch to zoom, except using a custom zoom function. So I basically want to "prevent default" while also capturing the pinch "delta". Surprisingly, there doesn't seem to be a good library for this!)

also: love this interactive demo 😍
