Is it possible in Blender to import and render raw volumetric data (outcome of fluid simulator)?

I have a set of 3d arrays of floats in C/C++ and I used to render it frame by frame with OpenGL using splatting. Now I would like to use Blender ray traycer to get much more realistic results. I would like it to look like a dense smoke. It would be nice to have realistic looking shadows and lighting too.

I appreciate any help.

EDIT:

I suppose Voxel Data with 8 bit raw files is the way to go.

I found this article. Following Leopold's comment gives me empty results. My files. I feel I am close to the final solution, what am I doing wrong?
