It seems like someone had developed a macro that would produce a mesh from an
isosurface.  Is that still available?  Could someone direct me there?

Thanks.

The original webpage of Kevin Loney's Approximation Macro seems to no 
longer exist, but there's a copy of his macro, and the version modified 
by Jaap Frank, in the download file in my isosurface tutorial.

http://www.econym.demon.co.uk/isotut/approx.htm

Be warned: In the vast majority of cases, the total time required to 
parse and render the approximation is greater than the time taken to 
render a real isosurface.

Right, but, it is able to save the parsed file, correct?  And also, I have never
yet tried it, but I thought that there was a way with PoseRay to convert a POV
mesh into an .obj format.  Is this true?

Oh, and thanks for the link.  :)

Hmmm... maybe using a mesh will resolve the problems I am having here:
