Shape.getVertexY returning always same data ?

Hello,

I'm making some test with a cube I created, I'm trying to detect the side facing bottom or top or ...

But when I use the getVertex or getVerterX/Y/Z I always get the same value from the vertices even if my cube is moving and rotating.

My cube :
2. void createCube() {
3. s = createShape();
4. s.beginShape(QUAD);
5. s.fill(col, alpha);
6. //bottom
7. s.vertex(-size/2, -size/2, size/2);
8. s.vertex(size/2, -size/2, size/2);
9. s.vertex(size/2, -size/2, -size/2);
10. s.vertex(-size/2, -size/2, -size/2);
12. //left
13. s.vertex(-size/2, -size/2, -size/2);
14. s.vertex(-size/2, -size/2, size/2);
15. s.vertex(-size/2, size/2, size/2);
16. s.vertex(-size/2, size/2, -size/2);
18. //top
19. s.vertex(-size/2, size/2, -size/2);
20. s.vertex(size/2, size/2, -size/2);
21. s.vertex(size/2, size/2, size/2);
22. s.vertex(-size/2, size/2, size/2);
24. //front
25. s.vertex(-size/2, size/2, size/2);
26. s.vertex(-size/2, -size/2, size/2);
27. s.vertex(size/2, -size/2, size/2);
28. s.vertex(size/2, size/2, size/2);
30. //right
31. s.vertex(size/2, size/2, size/2);
32. s.vertex(size/2, -size/2, size/2);
33. s.vertex(size/2, -size/2, -size/2);
34. s.vertex(size/2, size/2, -size/2);
36. //back
37. s.vertex(size/2, size/2, -size/2);
38. s.vertex(size/2, -size/2, -size/2);
39. s.vertex(-size/2, -size/2, -size/2);
40. s.vertex(-size/2, size/2, -size/2);
41. s.endShape();
42. }
44. void update()
45. {
46. translate.add(speed);
47. position.add(translate);
48. }
50. void display() {
51. pushMatrix();
52. s.translate(translate.x/frameRate,translate.y/frameRate,translate.z/frameRate);
53. translate.set(0,0,0);
54. s.rotateX(rot.x/frameRate);s.rotateY(rot.y/frameRate);s.rotateZ(rot.z/frameRate);
55. rot.set(0,0,0);
56. shape(s);
57. popMatrix();
58. }
When I try a s.getVertexY/... I get always the same thing...
What am I doing wrong ?

Best regards,

E.D
