Hello everybody,
I am working on texture simulation, and I wanted to know if it is possible
to export a Matlab surface in Povray (extension .pov).
I have done my homework by searching on the internet, but the solution that
I founded don't work with the matlab version I have (7.0).
Besides I am not really in computer science, and I do need something simple
(just press a button is perfect for me!!).
By advance thank you very much.
Pierre

Hi!
Which format is your surface in? I got no Matlab at the moment, but
usually it would be something like this, right?
x = [0:0.1:1];
y = [-1:0.1:1];
[X,Y] = meshgrid(x,y);
Z = exp(X).*Y;
If that's the case, triangulation should be straightforward. I can put
something together later (when I'm at a puter which has Matlab installed).
Even if you've got a finished surface displayed in a figure window it
should be possible to export it without too much hassle, although it'll
be slightly more complicated.
If you can give me some more details about what you need I'll see what I
can do :)
Greetings,
Florian

Hi Florain, and thanks for your answer,
I partially solved my problem by using your method!
In fact I exported some surface (3D surface: only defined by the altitude
the size and the step)from an apparatus. Then I translated them into .txt,
read them with matlab. My goal was to simulate the lighting behaviour of
the surfaces using povray.
What I did , was to convert the surface (obtained with meshgrid) into a .obj
and then to a .pov using PosRay.
Greetings
