I want to export smoke of blender. I wrote some code to read df3, and here
https://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Render/POV-Ray

it says "A DF3 file (POV-Ray voxel format) is exported. I want to know where is
this file.

I have tried render a scene from it.

I hope I can explain this.
In Blender with the render set to PovRay. Go to the scene properties 
(camera icon). Open the "Output" property and you will see the o/p 
directory. Mine reads /tmp/ Click the folder icon and Blender will show 
you where the Pov file should be saved.
I've not tried using df3s myself. Although I found and reported a bug 
using boids.

Keep us informed on how it goes.

One more thing
In Properties deselect "Delete files" and select POV Editor. That way 
when you start to render PovRay will open and if the scene fails it will 
be loaded into PovRay

Hmm I tried change the output directory to D:\ but it doesn't save the files to
that. I found the .pov and output image on user\AppData\Local\Temp directory
where PovRay message shows. Opening the .pov I found the df3 path finally. It is
on
....user\AppData\Roaming\Blender Foundation\Blender\2.79\preview\smoke.df3"
Windows 7.

Thanks for the response.

Sorry, I did some checking and that o/p location is for the render o/p. 
My pov files are saved in the same location that the blend file is saved in.
I do have some files in %appdata%\Blender Foundation\Blender\2.79\preview

But they are associated with a file that had packed textures. I don't 
know what happened there.

I have another question: I found the df3 file of the blender exporter is just
one byte depth data, (I know povray df3 has one byte or two bytes variation), is
there an option to two bytes data? I wish my data is more accurate. Thank you.

I've not used Blender with df3s so I will leave Maurice to answer.

you could use the 'df3util' program to convert from 8-bit to 16-bit (or
32), posted in p.b.u on 27th July last year.  hth.

Thanks for bringing up this topic. I had not tried Blender's smoke 
before. It is very interesting playing with it.
The exported smoke texture I get is not the same in PovRay as rendered 
in Blender.
