Dear all,

I have a 3D image stored in a 3D array myimg(x, y, z).
How can I get an artitrary sectional slice image fro such a 3D array
(Not only along x-, y- or z- direction).
Namely, given an arbitrary plane with (point, normal_vector) in 3D
space, which indicates
that this plane goes through point "point" and normal vector is
"normal_vector",
we can easily get the image laied in this plane.

Certainly, we can get the data in arbitrary plane by interpolation. I
only wonder if
there is an existing function in IDL ? (my version is 6.0)
