Why is an external a better solution ?

Anyway. I was inspired to make a bézier patch. It's an integer solution, 
so, for 17 points I run t from 0 to 16 instead of to 1, then I divide by 
pow(16,3) at the end to compensate. I could redo it in floats with almost 
the same number of boxes though.

Here's the screenshot of the whole patch :


It takes only 9 (nine) objects to compute it. For large numbers of points, 
I can add a cache using two more boxes. Float requires two extra boxes 
(and editing some more). Using a different order doesn't require any 
repatching, just edit three or four boxes to change some numbers (I'm not 
counting the fact that you have to recreate the multi-numberbox at the 
right to have more rows). When I count the objects I'm not counting the 
multi-numberbox nor any of the objects on the left. The wire that goes up 
is carrying the polygons ready to be rendered.
