Xray and other fresnel effects

[Walli]

Hi,

TG2 offers a Get Normal shader, which you can use to calculate a color depending on the surface normal - at last this is what I understand ;-)

Is it possible to transfer this into something like an Xray effect?  So that at glancing angles you could have a different color compared to the rest?

thanks,
Walli

Sounds like something to play with to see what happens.  I can't right now, but I probably will try it this weekend.  Or better yet, someone try it and post your results so we can see it now.

yes, I have such a function in my book of magic.
No really, I have something like that buried somewhere. Will look it up.

Cheers;
Frank
