Hello everyone again, got it, I think I've figure my problem out, at least I've got the result I wanted. This is how I proceeded, please tell me if this could be improved.
I have a TriangleFanArray with 10 vertices. Vertice 0 is the center of the octogon, vertice 1 through 9 are positioned on the "bounding" circle of the octogon. Now to make some kind of correspondace I took the 10 points and place them as if they were describing a TriangleStripArray. Once this is done I have a perfect quadratic form. This time is just a matter of dividing the picture in 4 and assigning the points as follows 1---3---4---6---8 |\ |\ |\ |\ | | \ | \ | \ | \ | | \| \| \| \| 0---2---5---7---9 And that's about it. Anyhow if you have comments go ahead and post them, maybe there's a faster way to do this.
