Polygons

Hi, whenever I create some of my polygons, they never get filled in, the fill method has been called and the points appear, but it never fills it?

import processing.opengl.*;
float x = 0;

 void setup()
 {
   size(800,600, OPENGL);
 }
 
 void draw()
 {
 translate(width/2, height/2);
 background(255);
 lights();
 rotateZ(0);
 rotateY(x);
 rotateX(0);
 //noStroke();
 scale(3);
 
 fill (120, 120, 120);
 beginShape(POLYGON);
 vertex(5, 5, 0);
 vertex(-5, 5, 0);
 vertex(-5, -5, 0);
 vertex(5, -5, 0);
 endShape();
 translate (0, 50, 18);
 //main front wing
 box(60, 5, 20);
 
 //side of wing
 fill (120, 120, 120);
 
 beginShape(POLYGON);
 vertex(30, -10, 15);
 vertex(30, 5, 15);
 vertex(30, 0, 0);
 vertex(30, 5, -15);
 vertex(30, -10, -15);
 vertex(30, -5, -5);
 vertex(30, -10, 15);
 endShape();
 
 beginShape(POLYGON);
 vertex(-30, -10, 15);
 vertex(-30, 5, 15);
 vertex(-30, 0, 0);
 vertex(-30, 5, -15);
 vertex(-30, -10, -15);
 vertex(-30, -5, -5);
 vertex(-30, -10, 15);
 endShape();
 
 //wing holders
 translate (-5, -5, 0);
 box(5, 10, 5);
 translate (10, 0, 0);
 box(5, 10, 5);
 translate (-5, -10, 0);
 
 translate (0, 0, 18);

 vertex(30, 5, 25);
 vertex(15, 5, 15);
 vertex(15, 5, -10);
 //vertex(0, 5, -30);
 endShape();
 
 fill(255, 255, 255);
 
beginShape(POLYGON);
vertex(0, 5, -30);
vertex(15, 5, -10);
vertex(10, 0, -10);
endShape();

beginShape(POLYGON);
vertex(0, 5, -30);

fill (255);
translate (0, 10, 52.5);
box (70, 20, 55);
translate (0, 0, 32.5);
box (60, 20, 30);

 
 x = x + 0.01;

Try building the same objects using TRIANGLES or QUADS, instead of POLYGONS..

you may be getting bitten by this bug:
http://dev.processing.org/bugs/show_bug.cgi?id=111

though you also should avoid the shapes coming back around to meet themselves, because that will prevent things from being filled.
