Indigo Renderer Forum

Are there scattering direction (-1...+1) examples u are aware of.
Maybe even rendered with indigo same scene, especially dust/fog

Like Example 6: Phase function on:
http://www.vray.com/vray_for_3ds_max/ma ... ples.shtml

Maybe some other SSS test's with same scene, where u can see how changing parameter affects output.

Not that I know of, Meelis :/

I can even say that this page was informative for me regarding phase function (the three graphed lobes).

According to them I was wrong when in assuming that an H-G phase function of 0 was scattering light almost orthogonally to the incoming ray direction. Rather, it should give results similar to an uniform phase function (non HG).

Hopefully that's the same object than in Indigo, so my new interpretation is correct.

Pretty complicated stuff to me.

found an article what i don't really understand mutch.

"highly anisotropic phase functions resulted in more light reaching the nucleus than was the case for isotropic phase functions"
Meaning of that unknown to me

But visually HG from 0 to +1 looks quait a same (@ vray example). While HG -0,9 didn't look soo good for dust/fog.

Still uniform vs HG give a very different result in Indigo.
Too bad it's soo slow to test all variations out But one day with GPU help, why not
