[REQ] InfraRed & UltraViolet light

Does indigo generate InfraRed and/or UltraViolet light?
I don't think so but that would be a really stylish feature!

We could then creat neat night shots, and maybe xRay-ish effects

Anyway, I want new shaders (SSS, custom) more than this.. ..at first

Nick?

Extending the range of frequencies simulated would slow down everything, so it's not a good idea, especially when 99% of the time such light is invisible

Ahh.. yeah, okay

I just think it's a cool thought

<wave_length>720-60000000(nm)</wave_length> == InfraRed
<wave_length>380-720(nm)</wave_length> == Normal
<wave_length>10-380(nm)</wave_length> == UltraViolet
<wave_length>0.01-10(nm)</wave_length> == X-Ray

Maybe this is what will crush Maxwell and all the other renderers

hehe

Anyway, it's you that decides

Hi, what is SSS I keep hearing it but have no idea. I did a google and wiki search before anyone flames me with "ever heard of google?"

Sub Surface Scattering (SSS) is a kind of shader that makes the object light transparent.
Three good examples:

This effect is called Sub Surface Scattering (SSS)
