Using leapmotion to control Unity3d interface - unity3d

Question

I understand that I can use leapmotion in game with Unity3D.
What I can't see any information on, is if I can use it to actual interact with assets, models etc as I build the game. For example revolving a game object around the x axis or zooming in or out of the view.
Is this possible?

Answer 1

Yes, it is possible, but requires some scripts that nobody has written yet (ASFAIK). Here is a VERY rough example that I worked up today since I've been curious about this question, too.
All it does is move, scale, and rotate a selected game object -- it doesn't try to do this in a good way -- it is a proof of concept only. To make it work you would have to do a sensible conversion of Leap coordinates and rotations to Unity values. To try it, put this script in a folder called "Editor", select a game object in the scene view and hold a key down while moving your hand above your Leap. As I said, none of these movements really work to edit an object, but you can see that it is possible with some sensible logic.
#CustomEditor (Transform)
class RotationHandleJS extends Editor {
var controller = new Leap.Controller();
var position;
var localScale;
var localRotation;
var active = false;
function OnSceneGUI () {
e = Event.current;
switch (e.type) {
case EventType.KeyDown:
position = target.transform.position;
localScale = target.transform.localScale;
localRotation = target.transform.localRotation;
active = true;
Debug.Log("editing");
break;
case EventType.KeyUp:
active = false;
target.transform.position = position;
target.transform.localScale = localScale;
EditorUtility.SetDirty (target);
break;
}
if(active){
frame = controller.Frame();
ten = controller.Frame(10);
scale = frame.ScaleFactor(ten);
translate = frame.Translation(ten);
target.transform.localScale = localScale + new Vector3(scale, scale, scale);
target.transform.position = position + new Vector3(translate.x, translate.y, translate.z);
leapRot = frame.RotationMatrix(ten);
quats = convertRotation(leapRot);
target.transform.localRotation = quats;
}
}
var LEAP_UP = new Leap.Vector(0, 1, 0);
var LEAP_FORWARD = new Leap.Vector(0, 0, -1);
var LEAP_ORIGIN = new Leap.Vector(0, 0, 0);
function convertRotation(matrix:Leap.Matrix) {
var up = matrix.TransformDirection(LEAP_UP);
var forward = matrix.TransformDirection(LEAP_FORWARD);
return Quaternion.LookRotation(new Vector3(forward.x, forward.y,forward.z), new Vector3(up.x, up.y, up.z));
}
}
