Fogscreen (Community Challenge)
Re: Fogscreen (Community Challenge)
Well.. I'm not completely sure how film projectors work, but if they rely on light passing through the film without being scattered, then that won't work in Indigo right now.
Re: Fogscreen (Community Challenge)
What will happen when I'd blend a diffuse material with a null material. The diffuse would
contain the image I wanna project and it would be lit with the technique I did post in the
beginning of this thread (projector link). Would that scatter the light too?

The diffuse material will scatter the light, yes.
Re: Fogscreen (Community Challenge)
Ok. In theory, if I could give a medium a texture and the medium would have an IOR of 1.0
and has absorption too, then it would work. Do I understand that right?

Re: Fogscreen (Community Challenge)
Yup, although IOR > 1 is fine too.

Ono, that specular-based, film material is an interesting idea wich I don't want to discard because it goes straight to the point, but how about expanding diffuse_transmitter with a scalar, phong(-ish) lobe ? We discussed that already... That would be a phong_transmitter maybe ?
Even though d_t is "not physical" it has proven to be very usefull, and imho that extra lobe would add versatility and relevance, ?
But again an ideal film has no scattering at all (~= infinite phong exponent) so the texture lookup trick on specular might fit best here.

Actually, after some more thought, and seeing that Enrico wants a similar material for stained glass, I think I'll augment the specular and glossy-transparent materials with a new parameter called 'absorption layer transmittance', which basically allows you to set the colour of an absorbing coating over a specular or glossy transparent material.

thats just great, ive been waiting for this for ages
