beta 2.5 Absorption preview

[radiance]

Hi all,

The upcoming beta 2.5 has a new feature, and absorption input on the specular material.
Check the render attached for an example.

transparent glass with slight amount of green absorption

Absorption uses beer's law to absorb colour in light as it travels through the transparent medium,
giving less colouring when going for short distances through the medium, and more colouring when traveling long distances.
Additionally, you can define the scale of the absorption using a float parameter.

Using absorption you can create much more realistic transparent materials such as glass, plastics, etc... in a physically correct way.

This will be supported in beta 2.5 which is nearing completion and will be posted in a few days...

Sweet, i just googled it. Looks like very complicated math and coding happening here Cant wait to test it out

Thank you Radiance, looks great.
I am curious to know what load that adds to the kernel. The image posted needs a bit of cleanup - how long did that render on your rig?
