Could someone explain ?

Hi,

I was reading this here http://wiki.blender.org/index.php/Dev:2.6/Source/Render/Cycles/Units

We currently do not support spectral rendering, and only use RGB colors. Part of the reason is that Open Shading Language also uses RGB. Even if the shading system does not, integrators could still be made to use spectral colors, which would at least make light interaction spectrally correct.

I know about the RGB part but what are “integrators” in this sentence ?

Thanks

Integrators are rendering methods like path tracing, photon mapping, bidirectional, etc. You could technically write an integrator that evaluates spectral rather than RGB values that could be converted to sRGB values on the fly by the color management.
