(The code below is a stripped version of a bigger project)

I need to know the x, y and z pos seem from the beginning.
If you look at the comment line you get what i mean, cause explaining here is really hard.

1. import processing.opengl.*;
   
   void setup() {
     size(600, 600, OPENGL);
   }
   
   
   void draw() {
     background(255);
     lights();
   
     pushMatrix();
     translate(width/2, height/2, 0);
     rotateY(radians(40));
     rotateX(radians(30));
     rotateZ(radians(20));
     scale(2);
   
     pushMatrix();
     translate(40, 60, 20);
     stroke(0);
     strokeWeight(10);
     point (0, 0, 0);
   
     popMatrix();
     popMatrix();
    
     //how do i find out the coordinates (xyz) of the point in able to draw on the same spot from here
    
   }
