Hi all,

I need to convert a 3D binary structure (1=structure, 0=no structure) to a format where it can be put into a surf command. So I think I need the X,Y,Z meshgrid coordinates of the surface of this structure, but I'm not sure how to get it. As an example of what I need, you can use the following to generate a 3D binary sphere.

[x y z] = meshgrid(-5:0.1:5, -5:0.1:5, -5:0.1:5);

r = 1;

img = sqrt(x.^2 + y.^2 + z.^2)<r;

Thanks for any help you can provide!
