Hey everyone,

Has anyone seen this link:  http://oldspeak.net/worldwind/

WorldWind Multitouch Plugin

This is a rudimentary, stub, C# WorldWind plugin which listens for multitouch input using the TUIO protocol, and interprets a basic set of finger gestures to control WorldWind. Supported gestures are single finger drag to spin the globe, pinch and spread to zoom, and two-finger rotate to roll the camera.

You’ll need:

* NASA WorldWind 1.4
* A working installation of touchlib or reacTIVision

I’ve been trying to get this Plugin for Nasa world wind to work but I keep getting this error message when I try and load it.

I’d love to get this plugin to work, as would a number of others.

Any thoughts?

UPDATE
New Version of Touch WorldWind aka Community Earth can be downloaded from nuicode or here http://mtaha.wordpress.com/2009/05/31/community-earth/

Nice find Fairlane.... I will try it soon and leave you feedback!

I’ve been waiting to try it also : )

Thanks guys, I just tried it on another PC with the same error. Haven’t tried to compile it myself yet.

Hi everyone.
I’ve just rebuilt it from source and it works fine.
Problem was missing assembly reference. You’ll need to add PluginSDK.dll WorldWind.exe and WorldWindow.dll references in order to build it.
Attached is working version.

Nice work skeeet! I thought it might have something to do with the compile/rebuild. Thanks for the updated version, I’ll try it soon…

Looking forward to try this out… thanks skeet.

Using OSC + simple-2point.avi works well too. Going to test it later on tonight and post results. The movement is limited but finally a plugin for Nasa WW that I happened to stumble onto while surfing the net! Yay!

Oh and thanks for updating the post too

Yes! I’ve been looking for this… very nice find!

I tried installing it on my DI-setup, but I can’t get it to work properly. It does receive some inputs, but not even close to a smooth experience. It seems the update-rate is not following the touchlistener, that outputs blobs realtime. Any ideas?

1 - Have a working TouchLib (rev. 359) nicely calibrated
2 - Installed WorldWind
3 - Installed pluin through WorldWind (also tried copying the file into the plugin dir)
4 - Had to create log-file manually on C: in order to load the plugin
5 - Started Vision.bat (osc.exe localhost 3333)
6 - WorldWind does react, but not as you would like it to - moves a bit, small increments, then stops, even though the Touchlistener keeps outputting.

Is it different gestures?

No, gestures is the same. It is how plugin should work for now. Will take a look at source soon and make some fixes. Also Fairlane wanted to do the same thing

Yeah it was all over the place. I fixed some issues like correct long/lat movement, fixed pinch and spread measurements and now looking into why it goes weird when you reach the dateline / poles. Also the rotate is a little off and needs attention.

Try this one out for some fixes, but more updates soon… (hopefully )

Yes, much better! I was a bit afraid it was something I had messed up in TouchLib somewhere… Looking forward to see what you come up with eventually, good work!

Thanks entity, I want to incorporate the tilt function (right mouse button) and clean up the code a bit. Too much to do and not enough time!

The pinch is really slow on my test setup (MTmini’sh sorta thing) , even tough i get excelent blobs and my rig is fast enough , the i do the gesture but it takes alot of time to actualy get somewhere.
Could you make it zoom-in faster with a smaller distance of fingers?Not all of us here have tables

Edit: I hope you understand what i’m trying to explain , when i try to zoom in with the pinch gesture or to fingers moving away from each other , even tough it starts zooming in and reacts quite nicely , the zoom-in action is slow as hell.

Something I’d like to add: you can configure camera behavior through Tools > Options. By playing with the settings (such as CameraRotationSpeed and CameraZoomAcceleration) I managed to make the previous version of the plugin to work quite reasonably. The only problem is that now I can’t find a way to reset the changed settings.

I’ll see how the updated version goes. Anyway, thanks Fairlane.
