[PD] int.lib for PD? (interpolating between numerous preset values)

Hi Joseph,
I did exactly that but in pd so I wonder who it was?
Anyway my patch is called pDM and can be downloaded at
It includes 2D interpolation of a number of variables. The corner values 
of each variable are set to specific values and the rest of the space is 
more or less linearly interpolated. Since 4 points are defined it will 
result in a somewhat curved surface. All this is described in the 
papers, see the readme.
Defining presets in arbitrarily positions in the space would be an 
interesting extension that needs some other method of interpolation.
