Hello all! I am having a bit of a difficult time implementing a multi touch library to a cover flow sketch I am using. I am using the SMT library here:  SMT Library Link

My issue is in the SMT cursor alignment with my mouse cursor. As you can see in this first basic sketch, the mouse cursor aligns fine with the SMT cursor point  illustrated with this sketch:

2. import vialab.SMT.*;
3. void setup(){
4.   size(400,400,P3D);
5.   SMT.init(this, TouchSource.MULTIPLE);
6. }
7. void draw(){
8.   background(125);
9. }

Now my issue is below when I am implementing a "cover flow" effect sketch with the basic SMT sketch, the coordinate point of the SMT object is all out of wack. The code is a bit too advanced, and I am trying to disect but am having a difficult time. 

code below:  (original sketch below found here)

2. import vialab.SMT.*;
3. 
   
4. 
   
5. final float MAX_ANGLE = radians(70);  // ジャケットの最大傾斜角
6. final float interval = 500;           // 間隔
7. final int   offsetZ  = 400;           // Z方向の移動分
8. final int   bgColor  = color(255, 255, 255);

16.   size(400, 400, P3D);

18. //SMT.add(new ButtonZone("TestButton",100,100,200,200,"Button Text"));

24.     p[i].nX = (i - p.length / 2) * interval;
25.   }
