You don't quite have an understanding of what Isosurface does.
Isosurface will find an equal potential surface within a regular mesh
using a variant of the marching cubes algorithm. What you want to do
is just define the order of your points to be row major and define
them as a grid with a 'locations' component as you did. Then use
ShowConnections to see how your object is importing.

This must be a simple thing to do but I am having problems.
I have a series of data that represent points in 3D space, which
essentially form a deformed sphere. I thought that if I attached to
each point a constant data value, say '1', then all I would have to do
is to use IsoSurface to form a surface from all the points with the
data value '1', .i.e. all points
Thus my data set of 'n' points looks like n lines of :
x y x 1
.... etc
In my case the number of points is formed from sampling a sphere
at 3 deg intervals in theta and phi, yielding 120 x 60 = 7200 points.
Isosurface needs connections, so read the data set in using the
data importer as a 120x60 regular grid with two fields. The first field
I changed to 'locations', as a 3-vetcor field, and the second I
changed to 'data' as a scalar field.
I then hocked up the IMPORT module to the ISOSURFACE module
and IMAGE. But I don't get anything out.
Is there something obvious I am doing wrong.
Any help would be appreciated.
