class Shape contains two methods drawCircle() and drawTriangle(). Each 
function takes different set of arguments. At present, I invoke this 
by calling the pde file directly. How to pass these arguments from a 
HTML file directly if I have to control the arguments being passed to 
the draw function? 
1) Example.html has (current version) 
<script src="processing-1.0.0.min.js"></script> 
<canvas data-processing-sources="example.pde"></canvas>
2) Example.pde has 
    class Shape { 
         void drawCircle(intx, int y, int radius) { 
              ellipse(x, y, radius, radius); 
        } 
         void drawTriangle(int x1, int y1, int x2, int y2, int x3, int 
y3) { 
              rect(x1, y1, x2, y2, x3, y3); 
        } 
    } 
    Shape shape = new Shape(); 
   shape.drawCircle(10, 40, 70); 
I am looking to do something like this in my HTML file, so that I can 
move all the functions into a separate file and call them with 
different arguments to draw different shapes (much similar to how you 
would do it in Java) 
A.html 
<script> 
Shape shape = new Shape(); 
shape.drawCircle(10, 10, 3); 
</script> 
B.html 
<script> 
Shape shape = new Shape(); 
shape.drawTriangle(30, 75, 58, 20, 86, 75); 
</script>
2) Iam using Example2.pde has 
void setup()  {  
  size(200,200);  
  background(125);  
  fill(255); 
}
  void rectangle(int x1, int y1, int x2, int y2) {
          rect(x1, y1, x2, y2);
}
My Example2.html has 
    var processingInstance;
    processingInstance.rectangle(30, 20, 55, 55);
but this is not working. How to pass these parameters dynamically from html.
