How to export .obj file from Matlab 3D Figure

I have created a 3D graph of a gyroid using the following code:

 a=1

a =

     1

>> f = @(x,y,z) sin((2*pi*x)/a).*cos((2*pi*y)/a)+sin((2*pi*y)/a).*cos((2*pi*z)/a)+sin((2*pi*z)/a).*cos((2*pi*x)/a); >> interval = [-0.5 0.5 -0.5 0.5 -0.5 0.5]; >> fimplicit3(f,interval)

How can I extract the graph as an .obj file. I tried using these functions: http://www.aleph.se/Nada/Ray/matlabobj.html#2

But I cannot manage to get it to work. Any help would be greatly appreciated as I know it is not too complicated. Thanks

Hi, I have the same problem: I have a trisurf plot and have to export it as an .obj file. Can you explain me how you've overcome the issue?

I don't know whether it will serve the purpose or not, but still, give it a try!!!
