The three numbers can be seen as PVector.
So you have lines and each line has 4 PVectors
So you can make a 2D grid of PVector
You need to use split() command several times:
-
One you did already
-
Next at
"],"(remove [ ) -
Next at , to fill the PVector
You can see the list as a list of quads / rectangles in 3D
