I don't get it...the points don't appear?!?

Is there any special code needed for points in 3D/OpenGL?

Heres my code (without the rotating methods)

import processing.opengl.*;
import damkjer.ocd.*;
import java.awt.image.*;
import java.text.*;
import processing.opengl.*;
import javax.media.opengl.*;  


Camera camera1;



void setup()
{
 size(800, 600, OPENGL);
 noStroke();
 camera1 = new Camera(this, -300, 0, 400);

}

void draw()
{
 
 background(125);
 lights();
 camera1.feed();

 
 //Sphere #1
 noStroke();
 pushMatrix();
 translate(50,100,10);;
 fill (85,198,23);
 sphereDetail(60);
 smooth();
 sphere(40);

 
 
 
 //Sphere #2
 noStroke();
 translate(20,50,70);
 fill (23,23,198);
 sphereDetail(60);
 smooth();
 sphere(40);

 
 
 //Sphere #3
 noStroke();
 translate(20,100,50);
 fill (249,145,22);
 sphereDetail(60);
 smooth();
 sphere(40);
 popMatrix();
 
 

 zoomZ();
 rotateIt();
 //helixA();
 
 pushMatrix();
 for (float z = 0 ; z < 2*PI ; z += 0.1) {
 stroke(3);
 fill(255);
 point( cos(6*z), sin(6*z), z);
 line(  cos(6*z), sin(6*z), z,6*z);
  }
 popMatrix();
 
}
