Version 3.5.beta.RC5.icl.win32


In 6.10.5.1, range_divider (photons/advanced technique)

There is a "TODO" ... is there any hope for it ?






In 6.5.4.2 Functions in Isosurface,

the equation for the .gray seems bogus, it is given as
   gray value = Red*58.9% + Green*11.4% + Blue*29.7%

which means that Red is brighter than Blue which is brigher than Green.
IMHO, for the human eyes, it should be
   gray value = Red*29.7% + Green*58.9% + Blue*11.4%
(Because Green is brighter than Red which is brighter than Blue)
Unless Pov is made for some insects or bees ?
