Have you read

> http://wiki.povray.org/content/Documentation:Tutorial_Section_3#Bicubic_Patch_Object

?

The corner of each grid should match. (aka, duplicate them)
The control points along the jointing line should also.

Do you really want to manage the 16 points of patch with 0-15, or use a
double index 0-3,0-3 instead ?

(array[n][4][4])

Or even simpler to understand: array[n][m][4][4]
n height
m width (as number of patch)
