just in case, I suppose you didn't forget to specify the framerate you want?

Code:

void setup() {
  frameRate(30);
}

void draw() {
  // ...
} 

can you post your whole code, so we can see where is the problem?

my code is here:
it was working but now it is not working :(

it is not whole code....

void setup() {
 size(320,240,P3D);
 loadPixels();
colorMode(RGB,1.0,1.0,1.0,1.0);

background(0);
 m = new JMyron();
 m.start(width,height);

 m.findGlobs(1);
 m.adaptivity(50.0);
 loadPixels();
 // rectMode(CORNERS);

 pt2=map2;
 framerate(40);
}

float lu(int x, int y, float array[]){    // look up a table
 return(array[(y*width)+x]);
}

void display(int [][] lst) {
 for (int i=0;i<lst.length ;i=i+1) {
   int x = lst[i][0];
   int y = lst[i][1];
   splash(x,y,.1,2);        // Create splashes where mouse cursor
   //rect(x-1,y-1,x+1,y+1);
 }
}


void draw() {
 m.update();
 m.imageCopy(pixels);
 updatePixels();
 display(m.globCenters());
 //  water effect 2
 for(int j=1;j<height-1;j++){      
   for(int i=1;i<width-1;i++){
     pt1[i+j*width]=.70*(((  lu(i+1, j,   pt2)+  lu(i-1, j,pt2)+  lu(i,   j+1, pt2)+  lu(i,   j-1, pt2)  )/2.)-lu(i,j,pt1));
   }
 }

when I type frameRate, it is still not working

ok i solved it, one of the library, i have imported, was the problem. thanks for help...
