  How to make an isosuface from 3D array ? (Message 1 to 7 of 7)

I have an 3D array (x,y,z) with value between 0 and 1.
I want to make an isosurface from this array.

How would you proceed ?

(I started with the idea that i would require a interpolating function for
knowing the value anywhere in my array to have a smooth function. Even with
that i have no isosurface)

Please someone give me a sample code !!

I create my 3D Array inside pov and pov can only write ascii files (density
files are not ascii files). Can someone help me ?

you can write layers of array to images and then convert set of images to df3
file. http://www.users.on.net/pod/df3/
