Subsurface scattering support #269

Open straaljager opened 5 years ago

straaljager commented 5 years ago

Hi,

I checked out the new Principled shader introduced in Ospray 1.6, but couldn't find a subsurface parameter as in Disney's original PBR shader implementation (https://github.com/wdas/brdf/blob/master/src/brdfs/disney.brdf)

Is there some way Ospray can do SSS?

Thanks

@johguenther may give a better answer, but as far as I know we do not yet compute any subsurface scattering in our shaders. however, people asking for it is a good way of getting new features in ospray down the line:)

johguenther commented 5 years ago

Agreed, having SSS in OSPRay would be cool. But please don't expect it very soon, many other features also wait to be included...

straaljager commented 5 years ago

Thanks for your replies. Good to know it's on the radar.

I know this is an old post, but I would add my interest in subsurface scattering. Even just a backscattering component in combination with transmission color & transmission depth would be valuable.
