hey, that's nice!
A whole arsenal on nk-colours :shock:
I dunno, if there is any way to prevent the interface to be too big, but what about simulatneous convertion?
you put in ONE type of values (i.e. rgb or nk) and all the rest will be added.

and instead of listing them all up (which is great, but uses a lot of space), you could add sliders, that put in the degree value. Those could be much more accurate than this per-degree-view.
Is it possible?

Also, a "switch view"-option would be great!:
This vview and the view with sliders, that I descriped :D

I'm not productive yet with it, but indeed it has evolved quickly !

bump for this very useful program I just discovered for creating your own NK data files 8)

thanks to this program I finally have some materials for my Alien stuff 8)

basic Phong doesn't really do the same thing.. tests of the same colour, varying the exponent of both from 1 to 1million
and IOR from 1 to 100 for Phong as well

The NK version only displays the colour in the highlight areas, but tends to be black in other parts. EVen though the NK plot doesn't show any black
A blend material of both would be interesting....

Now I can put the finishing touch on my Alien Artifacts scene and finalise a render after 3 attempts at it with Phong!!! :evil:

now if you could vary the IOR for NK data on a overall level then we would be set.....

nk is complex IoR, which means, as far as I understood it, it finds differently strong colours for different IoR... so, it is a matter of varying the position of some of the lines, I'd say...

(not sure, though)

well dark colours have lower IOR when converted to NK.

I don't know how the the Reflection curves are calculated but they are all different for each colour you create

I looked at the curves and my results are quite interesting, sometimes^^ - try 50% grey WITH gamma correction -> strange IoR curve :)
