I am drawing trapezoidal parts of a shape and while the the top and bottom seem so have no problems, the sides seem to be constructed from triangles and not quads. Btw, this was based on the 'textured cube" example.

EDIT: Added Screen Shot.


This screen shot is from 2.06a on Windows 7.

1.   beginShape(QUADS);
     texture(tex);
   
     //top
     vertex(-2,  2, -4,  0, 0);
     vertex( 2,  2, -4,  1, 0);
     vertex( 4,  4,  0,  1, 1);
     vertex(-4,  4,  0,  0, 1);
   
     // mid
     vertex(-2, -2, -4, 0, 0);
     vertex( 2, -2, -4, 1, 0);
     vertex( 2,  2, -4, 1, 1);
     vertex(-2,  2, -4, 0, 1);
   
     //bott.
     vertex(-4, -4,  0, 0, 0);
     vertex( 4, -4,  0, 1, 0);
     vertex( 2, -2, -4, 1, 1);
     vertex(-2, -2, -4, 0, 1);
   
     // left -- HAS A CREASE FROM CORNER TO CORNER
     vertex(-4, -4,  0, 0, 0);
     vertex(-2, -2, -4, 1, 0);
     vertex(-2,  2, -4, 1, 1);
     vertex(-4,  4,  0, 0, 1);
   
     // right -- HAS A CREASE FROM CORNER TO CORNER
     vertex( 2, -2, -4, 0, 0);
     vertex( 4, -4,  0, 1, 0);
     vertex( 4,  4,  0, 1, 1);
     vertex( 2,  2, -4, 0, 1);
   
     endShape();

I can post the rest of the program if anyone thinks its necessary or easier to debug ( I am trying to recreate David Ope's black and white GIFs.)

I've got an Enttec DMX USB Pro and I'm using the dmxP512 library to send data to my device. This works on 1.5.1, but not on 2.0a5. I get a serial error on the alpha build and the release notes refer to changes in the Serial Library, however I cant seem to find anything with more information. Does anyone either have experience with the new serial library or reference on it?
