I have added a new swf plugin to the fov_plugins package that enables multitouch ("pinch") zooming on Windows 7 and Android based devices supporting multitouch. Just include the plugin in your xml, and multitouch zoom starts working magically on supported devices.

Quoting Klaus from a different thread:

Hi,
the reason for this is still the Android Flashplayer itself - it still doesn't support Multi-Touch events with more than 1 finger,
krpano itself can't change that,

I found that while it is true that the Flashplayer (and Air) for Android does not report multitouch gestures, it is possible to capture each individual touchpoint. So instead of relying on the zoom-gesture, my plugin tracks touch points and calculates the pinch "scale" when two or more fingers are used.

I have tested the plugin on both an Android device (Android 2.3.6, Flash Player 11) and a Windows 7 touch-enabled TabletPC. It probably also works on multitouch touchpads on the Mac.

The multitouch.swf file and its sources are available as part of the krpano_fovplugins package on github.

Enjoy

Updating the pages on github didn't go very smoothly, so you might have seen me fumble.

The example is intentionally left at a preview-grid. All that is exciting about the example is that pinching works on multitouch devices. If you don't have either a multitouch display attached to a Windows 7 computer, or an Android devices which supports Flash, there's nothing here to see.

Somewhere between testing and cleaning up the plugin, I must have broken something on the Android side of things.
I'll be right back.

Update: Hmm... bad news. I had been testing the plugin inside an AIR app, and it works great. However, it seems that the Flash Player inside the Android browser does not report multiple touchpoints. So the plugin will not work in the browser at this point :-(
