physx and index of refraction
show user profile  debodeebs
i have an extremely slow mind when it comes to physx so is there anyone else on here who also struggled to learn the maths of refraction and eventually learned it and if so what was your method of understanding easily?

Not sure about Physx - but when I first came across IOR I googled and then wikipedia'd it.

thanks, im trying to understand the wavelengths for understanding the reflections of materials, so using this website

you have to input a value for the wavelength therefor giving you the falloff curve chart to input in max's material output

Learning the exact math and theory wont make your renders beautiful. Experience and 'feeling' does that. Personaly, i havent th first idea of the theory of working out refraction and reflection. I mean, who the fek cares and why?

thats the down fall to watching other artists workflow and trying to follow their way as it only confuses things.

I don't know how all ya'll learned but this is my only training-

hot damn.

also I use this list and take artistic liberties when I get that warm fuzzy artistic feeling... nope that was just my phone on vibrate.

number 1 image was done using the typical vray plastic material and number 2 image is using the real life plastic wavelength from the website above.

no renderer that i know of uses physically accurate methods, rather they use approximations which can take quite a different path so physical intuition isn't always the right one here. All though, i guess understanding IOR would be important if they didnt teach you in school
