RGB to xyY color space conversion and luminance I think that both luminances should have the same value. |

deferred rendering and point light radius Ok. Attenuation is calculated and scaled based on luminance so maybe light color (Li) should be convert to CIE xyY space and Y component should be used during calculations ? After that a result can be converted back to RGB space. |

deferred rendering and point light radius What do you mean by cut off each of the RGB channels at slightly different places ? illumination I at distance d = intensity (rgb) Li * attenuation (defined as above) so where does it take place ? |

deferred rendering and point light radius Can I also express kl and kq as here: [link] (imdoingitwrong.wordpress.com/2011/01/31/light-attenuation) ? Then attenuation = 1 / ((d/r) + 1) ^ 2 and is scaled this way: attenuation = (attenuation - cutoff) / (1 - cutoff) where cutoff = minLuminance, right ? |
