I've been trying to get peasycam to work with the Leap Motion -- I've been trying to replace the mouse movement to move the cam in peasycam around a shape with movement on the Leap Motion.

I was able to get some control with the following code, but the rotation in peasycam seems to refresh with each new frame.

2. PShape s;
3. 
   
4. import peasy.*;
5. import com.leapmotion.leap.Finger;
6. import com.onformative.leap.LeapMotionP5;
7. 
   
8. LeapMotionP5 leap;
9. 
   
10. PeasyCam cam;
11. 
    
12. PeasyDragHandler RotateDragHandler;
13. 
    
14. void setup() {
15.   size(displayWidth, displayHeight, P3D);
16.    if (frame != null) {        
17.     frame.setResizable(true);  
18.   }
19.  
20.  
21.   s = loadShape("sculpture.obj");
22.   s.scale(6,6,6);
23.   
24.   cam = new PeasyCam(this, 500);
25.   cam.setMinimumDistance(10);
26.   cam.setMaximumDistance(800);
27.   
28.   leap = new LeapMotionP5(this);
29.   
30.   RotateDragHandler = cam.getRotateDragHandler();
31.   
32. }
33. 
    
34. void draw() {
35.   background(0);
36. 
    
37.   shape(s);
38.  
39.   for (Finger f : leap.getFingerList()) {
40.     PVector screenPos = leap.getTipOnScreen(f);
41.     println(screenPos.x + ", " + screenPos.y);
42.     
43.    RotateDragHandler.handleDrag(screenPos.x, screenPos.y);
44.     
45.   }
46.   
47. }

I tried to slow that refresh rate by first specifying a frameRate, but that didn't help much. I then tried to smooth out the refresh by adding a buffer around the x,y positions with each refresh. I was hoping it wouldn't refresh unless the change in the x and/or y was beyond a specified range. I think this slowed it a bit -- I'm able to hold the image steady at times -- but then movement seems to spin the view wildly out of control again. I'm printing the x,y values, and they're not moving beyond the range, yet the view is still spinning out-of-control. Here's that code with the attempt at smoothing it:

2. PShape s;
3. 
   
4. import peasy.*;
5. import com.leapmotion.leap.Finger;
6. import com.onformative.leap.LeapMotionP5;
7. 
   
8. LeapMotionP5 leap;
9. 
   
10. PeasyCam cam;
11. 
    
12. PeasyDragHandler RotateDragHandler;
13. 
    
14. int x;
15. int y;
16. 
    
17. int xx;
18. int yy;
19. 
    
20. void setup() {
21.   size(displayWidth, displayHeight, P3D);
22.    if (frame != null) {        
23.     frame.setResizable(true);  
24.   }
25.  
26.  
27.   s = loadShape("sculpture.obj");
28.   s.scale(6,6,6);
29.   
30.   cam = new PeasyCam(this, 500);
31.   cam.setMinimumDistance(10);
32.   cam.setMaximumDistance(800);
33.   
34.   leap = new LeapMotionP5(this);
35.   
36.   RotateDragHandler = cam.getRotateDragHandler();
37.   
38. }
39. 
    
40. void draw() {
41.   background(0);
42. 
    
43.   shape(s);
44.  
45.   for (Finger f : leap.getFingerList()) {
46.     PVector screenPos = leap.getTipOnScreen(f);
47.     println(int(screenPos.x) + ", " + int(screenPos.y));
48.    
49.    
50.    if (int(screenPos.x) < (x-50)) {
51.      x = int(screenPos.x);
52.    } else if (int(screenPos.x) > (x+50)) {
53.      x = int(screenPos.x);
54.    }
55.    
56.    if (int(screenPos.y) < (y-50)) {
57.      y = int(screenPos.y);
58.    } else if (int(screenPos.y) > (y+50)) {
59.      y = int(screenPos.y);
60.    }
61.    
62.    if (xx != x) { 
63.    RotateDragHandler.handleDrag(x, y);
64.    xx = x;
65.    } else if (yy != y) {
66.    RotateDragHandler.handleDrag(x, y);
67.    yy = y;
68.    }  
69.     
70.   }
71.   
72. }

Any suggestions as to what I could try to get this to work? Is there something I'm not getting about peasycam, or the way Leap is sending positions vs. what the mouse movement did? Is there a way to do relative movements, instead of absolute positions -- maybe the relative change in position is what peasycam uses?

Any help is appreciated. Thanks for checking this out.
