Hi,

For some time I tried implementing the scattering model described in this paper:

Salama Paper

The BRDF part of this paper is pretty clear and straightforward. Where I am hanging is the scattering part. When scattering at the first hitpoint once only, I'm just not getting the same results as proposed by the images in the very same paper. Of course I'm scattering multiply rays inside the proposed scattering cone and averaging the results of the different rays.

Does anyone have more or less concrete ideas on the implementation of this nice and beautiful illustrative rendering method.

I am glad and thankful for any hints.
