Photochromatic film material help?
How easy would it be to make a photochromatic film material - as used on the glass in this building http://www.unstudio.com/projects/la-defense-offices? I assume it would be similar in nature to the build up of this pearl material?
I'd like to incorporate it into a render, but I've not really created materials beyond standard building components. Would it be easier to apply post-production?
Thanks,
Jen

Hi,
It's more a dichroic filter. If you do not need to model light transmission, that could be done with a simple phong shader
You can find a simple one here :

Colors can be changed by tuning the "600.0" coefficient in the thickness function

Nice Etienne, I always wanted to see some wavelength dependent shader.

Re: Photochromatic film material help?
The pearl uses a wavelength dependent shader for a long time! This one is just a variation of the pearl
These physics based, wavelength and angle dependent shaders would be very nice in an animation to see the changing colors.
I never tried the parametric shaders yet, but I definitely should. Maybe that one is a good candidate

Re: Photochromatic film material help?
Those physics are above my head anyways
About params, I think the UV scale is needed first, whenever applicable; you never know the details frequency the user is looking for...
Also, Ono insisted on the slowness of the pow() function. Perhaps would it be worth declaring the sin() in a let statement to multiply it by itself below, if that power is not to be changed by the user.
edit: I see that you may be looking for backwards compatibility with shaders... Let's see what Jen says now ^^

Re: Photochromatic film material help?
Wow, thanks for the replies both of you!
Most of that went way over my head too, but that material looks like the kind of thing I was after galinette, thankyou (not sure why I hadn't spotted it in the first place!) I'll give it a test and update you on my progress
Thanks again!

Because I made it just after reading your postgjengi wrote:(not sure why I hadn't spotted it in the first place!)

Ah, hehe. Thanks!
Also, am I right in thinking if I wanted to make dichroic glass, that I could just blend that material you made with a glass material?

Yes, this could do the trick.
Other interesting test could be:
- Make a 8-10mm thick glass pane with a glass material
- Blend the dichroic material with a null
- Insert a single polygon layer halfway inside the glass pane and use the blend material on it
This would be similar to the actual glass, which is a dichroic polymer film sandwiched (laminated) between two glass panes

No no it's all galinette, I am just interfering !gjengi wrote:Wow, thanks for the replies both of you!
I hope that you will be able to share with us an image of his shader in action. Don't forget to use Glass Acceleration.

Nice one, galinette!
