does anyone here knows AR(augmented reality)??

Upvote for excellent and unique question, and introducing me to a type of development I hadn't considered.

yes.. and i welcome u for that..

so.. my big question here is how to create a script to use it with finger gesture like pinching(zoom), dragging(rotate) and what not..

do you want to roll your own code or buy someone else'? spk on the forums wrote code for a couple of finger gestures, such as drag, pinch, twist etc. http://forum.unity3d.com/threads/95983-RELEASED-FingerGestures-Robust-input-gestures-at-your-fingertips!

I havn't downloaded the SD$$anonymous$$ yet, but just watching the Vuforia video, they actually move the $$anonymous$$pot from the 'tile' by touching the screen and raycast screen point to world, then the model moves and retains its relationship to the parent 'tile' when the camera moves. It's all looking quite easy to implement (of course they make it look easy, but both videos I watched are developed in Unity). So my question would be : are you using the Qualcomm Vuforia system to implement AR, or using another product. I shall be playing around with the SD$$anonymous$$ this afternoon, and if the whole process (inc registration, getting the 'tile' image sheets in print and data form, implementation, etc) is done well and non-intrusive, I'll post back on my results for moving, rotating, scaling.

You know how to use Input.touches, right?

I tried Vuforia, it's pretty easy to use :)

Yeah, looks like that is true. It's hard not to get excited watching these video's!

Regarding Input.touches and code : That's why I asked if you have already built to iOS / Android (I'm in iOS). I have a few answers here I can link to covering Input.touches if you have not and are developing for iOS (they are just a small extension from the Unity API, so just the basics) =]

Wait until I download, or if you already have, just look at the $$anonymous$$pot example (if it's there).

This is the video I mentioned that showed the fellow moving the $$anonymous$$pot by touching and dragging on the screen :

Scroll down to : AR Tutorials/Workshops : then watch the first one : Tutorial: Qualcomm's Augemented Reality SD$$anonymous$$ / July 2011

exactly...

but the thing is.. how to implement the finger gesture without buying it..

i've already got scripts to drag, zoom and rotate... and its not AR..

its for touch screen devices that has built-in camera... and supports android and IOS..

*my brain hurts..

@alucardj and @purplelilgirl...

please let me know if you got any information or source scripting..

thank you for your kindness of helping..

nice, I rolled out my own code for that too, since I'm too poor/stingy to buy ready-made solutions, so need scripts? or you want to figure it out on your own?

I do not know if it has been said already but the book "Holistic program$$anonymous$$g with Unity", Penny de Byl has an introduction to AR. (I do not know the author and am not related to the book in any manner).

heh fantastic title, did not know about it! :)

It is actually Holistic Game Development with Unity. The book has some real good parts and some...less real good ones. But it has an introduction on AR like simply adding a cube on top of a camera capture and something about a GPS also (can't recall what exactly...).

@purplelilgirl... any help will do... and yes.. i do need the scripts.. i'll figure it how based on the script.. thanks..

@Fattie .. well.. so did i.. and its really new..

@zerox911

I got this script somewhere in the forums: Gestures.js, I based my code on this code (sorry I don't know how to format this >.<)

var panTranslate : Vector3 = Vector3.zero; var distance : float = 5.0;

/ vars used to track camera rotation /

var rotation : Quaternion; var position : Vector3; var x : float; var y : float;

var zoomSpeed : float; var speedFactor : float;

function LateUpdate () { / do other stuff /

 /* zoom in/out for two finger pinch */

 if ( Input.touchCount == 2 ) {

     var firstFinger   =  Input.GetTouch(0);
     var secondFinger  =  Input.GetTouch(1);

     var currentDist   =  firstFinger.position - secondFinger.position;

     var deltaOne      =  firstFinger.position  - firstFinger.deltaPosition;
     var deltaTwo      =  secondFinger.position - secondFinger.deltaPosition;

     var lastDistance  =  deltaOne - deltaTwo;

     var deltaDist     =  currentDist.magnitude - lastDistance.magnitude;

     distance -= (deltaDist * Time.deltaTime) * zoomSpeed * $$anonymous$$athf.Abs(distance); 

     /* clamp the distance so you can't get too close or far */

     //distance   =  clampDistance (distance, distance$$anonymous$$inLimit, distance$$anonymous$$axLimit);
 }

 /* pan for three touches */

 if ( Input.touchCount == 3 ) {

     var total$$anonymous$$ovement = Vector2.zero;

     for ( var thisTouch : Touch in Input.touches ) {
         total$$anonymous$$ovement += thisTouch.deltaPosition;
     }

     var pan$$anonymous$$ovement = total$$anonymous$$ovement / Input.touchCount;

     var deltaPanY  =  pan$$anonymous$$ovement.y * transform.up    * distance * speedFactor;
     var deltaPanX  =  pan$$anonymous$$ovement.x * transform.right * distance * speedFactor;

     panTranslate  -=  deltaPanY;
     panTranslate  -=  deltaPanX;

     /* clamp the pan vector to constrain movement */

     //panTranslate = clampPanTranslate(panTranslate);
 }

 /* ignore rotation for this example... */

/** rotation = Quaternion.Euler(y, x, 0); position = rotation * Vector3(0.0, 0.0, -distance) + target.position + panTranslate;

 transform.rotation = rotation;
 transform.position = position;
 **/

}

well... im gonna give it a try...

thanks.. if it didn't work.. im not bla$$anonymous$$g u...

Here are some links from the Unify Community 'site :

http://wiki.unity3d.com/index.php/Basic_iOs_Input_Tutorial

these two are JS for rotate, and have youtube links at the bottom (working script at bottom of page too) :

http://www.revelopment.co.uk/tutorials/unitytutorials/73-howtorota$$anonymous$$nobjectbytouch

http://forum.unity3d.com/threads/17382-Click-n-drag-iphone

All the other Unify Community scripts are in C#, but this is the one I learned from :

http://wiki.unity3d.com/index.php/Tap_to_$$anonymous$$ove_Drag_to_Look_iPhone

C# for reference :

http://wiki.unity3d.com/index.php/Finger$$anonymous$$anager

http://wiki.unity3d.com/index.php/DetectTouch$$anonymous$$ovement

http://wiki.unity3d.com/index.php/TouchLook

I have something I wrote for scaling if one of the pros don't provide a better structured answer first =]

Edit : Also check my answer here to rotate an object (JS) :

http://answers.unity3d.com/questions/289055/rotate-on-drag-for-ios.html

It seems like this question has turned from AR to iOS input !

thanks @alucardj... i'll check on it..
