Good morning,

I am trying to resample a part of a field using the Grid and Map
modules but the interpolation takes a long time (e.g. Pick'ing a
single point and feeding its position to Map takes 10-15 seconds
on my Octane, 768Mb).

The datasets I am working with are acquired from a 3D ultrasound
machine. The data from a 3D scan is stored in a block (average
size ~ 400x300x130 bytes). Each plane in this block is acquired
at a different angle. In order to describe the positions I use a
product array of a plane and a line. The line is a regulararray.
The plane is an array with the transformed positions according to
the angles. The connections are regular. What I have described is
the same as Example 6, Appendix B in the User's Guide, page 255),
only more points.

Any advice on improving the interpolation performance?  I am
scared to place a 10x10x10 grid somewhere in the dataset and do a
Map ;-)

Thanks,

Paul
