Thanks Padraig, i've looked at the example and that approach should do what i
want, after making a few modifications.
Unfortunately i know only very basic details about the inr format, and i'm
not able to find a lot of information.
I know that we can give scalar data for each voxel in a cubical image, which
is called its grey value.

Since i have a uniform grid of points on which i know scalar function
values, should i treat the points as voxels? (because voxels, according to
the int file documentation have a height, width and breadth, so that may not
be right for me)

Secondly can this gray value be negative, or should i shift the origin for
the data and give an adjusted isovalue?  because the domain of my scalar
function values is the real number space (same goes for the coordinates of
the grid of points i have), and in the inr file i inspected after loading in
matlab, i only saw positive values

Lastly should i use INRIA's zinrimage library(or cgal if it can write inr
files) to write an inr file, or should i follow what has been suggested by
someone in this approach (since i have points in cgal's data structures
already)

In the link above, the person has tried to eliminate the step where we write
to an int file and read from it again in cgal, by using the image_3
class(after changing it i think) 

Thanks again!
