Thanks! Toxis seems a way to go, but I'm not sure how to implement the timing periode?
How can I add the periode to this example:

1. import toxi.math.*;
   
   void setup() {
     size(200,200,P3D);
   }
    
   void draw() {
     frameRate(1);
     InterpolateStrategy linear=new LinearInterpolation();
     int h=height;
    
     print("----------------");
    
     for(float x=0; x<width; x++) {
       float t=x/width;
       //linear
       float y=linear.interpolate(0,1, t);
       println(y+",");
       }
      
     print("----------------");
