Hi all,
I am not a newbie to python and numpy, but however, I kinda do not
find a proper solution for my interpolation problem without coding it
explicitly myself.
All I want to do is to increase the resolution of an tree dimensional array.
I have a volume 'a'
a = numpy.random.rand(3,3,3)
Hi,
you can have a look at the method interp2d of scipy.interpolate.
I think it is what you are looking for.
Best,
Luca

You might want also to look into scipy.ndimage.zoom.

scipy.ndimage.zoom is exactly what you're looking for, as Zach Pincus
already said.
As far as I know, numpy doesn't have any 3D interpolation routines, so
you'll have to install scipy. Interp2d will only interpolate slices of your
data, not the whole volume.

Yep,
thats the one.
Unfortunately, installing scipy makes my project dependant on another
package. However, I installed it and it works...
Thank you

The ndimage package can be accessed as numpy.numarray.nd_image. scipy is not
needed

numpy.numarray.nd_image just imports from scipy.ndimage or a
standalone ndimage if you have built it so. numpy does not contain the
ndimage code.
