Ok, I messed around with the Face() object and it seems like it is
exactly what i was looking for, EXCEPT i can't figure out one tiny
thing as described below:
var hex:Face = new Face(); // Create Face object
hex.moveTo(0,0,0);
hex.lineTo(x,y,z); // x,y,z= some number
hex.lineTo(x,y,z); // x,y,z= some number
