about

PatternTouch - multi touch framework for vvvv, based on common user interaction patterns.

Features:

Translate, Scale, Rotate gestures (all via center).
Alpha channel support.
GPU based intersection analysis, especially useful for complex meshes.
Display List support via Group node.
Created with vvvv in mind.

In next releases:

Pan and Zoom gestures.
Transformation limits with iOS like behavior.
Multidirectional swipe gesture.
Photo Gallery module.

Limitations:

No sorting support. All transformations always sorted by ID.
No complex transformation hierarchies. For example, if you have a touchable element in container and want to scale this container, you need to touch container only in empty places. Upper object always receive all blobs.

Bugs:

VPA (PatternTouch Split) outputs zero AspectRation matrix if no input connected.

Hey alg,
first of all thanks for sharing your work!
I tried your PatternTouchDebug patch and I found a strange behavior. When I scale or rotate 2 objects at the same time (e.g. using a multitouch with 4 hands), sometimes the transformations work only on 1 object. In this case the ID number on the bug object is -1. I tested the patch with a IR multitouch frame.

@alg: sorry if I stress you, but also the IntersectGeometry help patch doesn't work as expected.

alg 14/03/2013 - 14:18

Hmm, never saw such behavior. This bug can be possible, because i tested this lib on dual-touch frame, so transformed only one object at once. Maybe this is the bug inside intersect geometry module.

@alg: code is not my friend. I can't understand what's going on inside IntersectGeometry.fx. I wait for your solution... :)

@Alec ok, i fixed it, will publish new release soon. Help patch also was fixed, thank you again for bug report.

Alec 21/03/2013 - 14:45

@alg: great! Can't wait! I need your new release to continue my tests... thanks!
