.:: Colored glass with bitmaps

I tested this Blend material approach for making bitmap-colored glass and it seems to work quite good. Here is an example of what i got.
I used medium material + phong material with texture map.
The material is in zip file. You can import it with Maxigo (and with all the other exporters that support *.igm)

you can see through but you can't

Those bubbles are inside the sphere

It's magic.

Yeah, looks cool, but I don't think it looks like anything *real*.
I like that view of the mat preview object

I agree. Doesn't look real. I tweaked a bit, but this is the best i got.
Anyway. I was quite sure, that this blend method doesn't work at all, but to my big surprise it somehow works. I kind of like remembered, that blend doesn't work with medium materials.

I already blended transparent mats...
two specular tranparent to simulate Birefringence...
I didn't test it and I guess, it's not accurate, as there can be positve and negative Birefringence
But it looks good

It didn't work previously, but I fixed it

Don't try and blend two transmitting specular materials together, though.

why?
It did work fine...

Post by **OnoSendai** » Mon Apr 23, 2007 6:18 am

Why?
because the behaviour is undefined

aha...
so, the result everytime looks different?
Is diffuse/phong + transparent defined?

i make some test too with bitmaps and glass for colored glass by bitmap...but the results is interesting but not realistic....for example we dont have caustics from this colored objects by bitmaps....we need an pure medium that takes an bitmap for color the surface.....i know Ono this is dificult to archieve but u have some idea????right?

i have faith to you Nick!
