Hologram shader, pseudo parallax mapping.

Hi everyone !
I'm working on a kind of hologram shader, a method introduce in Stupid Renderman trick 2008 from animal logic.
Here somes pics, Guerilla is really powerful to achieve this kind of effect and react in real time.
We could go really deeper than the SRT one.
Just need to pass messages from  Shader to Light, to get the working shadows for instance.
I was able to get bssrdf on it, see the last pics, this is the default values don't blame me for that.

Hi Pixo,

Is it the famous hologram shader used on Happy feet, to make pseudo subsurface block in ice ? It's look like it.

Hello MattRm

Yes this is the base,

To make it look exactly the same, we just have to use the render cam as an holo cam.
It just need messages passing shader to light to make it deeper .
It could be called spacial relighting, since in reality this look to be it.

Re: Hologram shader, pseudo parallax mapping.

Hi Ben  !

This is not a relight shader :p, i just told that it look to be the same concept, but in a 3d space a the end.
See an example of application http://www.renderman.org/RMR/Examples/s … A_2008.mov
Actually with Guerilla this shader is allready deeper than the presented one with a real time representation.
Just need message passing shader>lighting,to finish the stuff.

Anyway the relighter will not be in 3d , and like Gam use to say "i don't drink coffee".

Guerilla is good enough to don't ask for every features on the planet earth.
Even if i'm more than impatient for the Relighting one.

PLEASE ! Just unlock the core variables, message passing shader>light, and, a customisable color range output!
It will be faster than doing a relighter, and, you'll need it as well .
I'm sure i'm not alone to waiting for it.

Keep the good work, Cyril and you are genius.

PS:I know that i look a little bit impatient,
but Guerilla is so good that when littles things miss to make huge things,
it make me so frustating.

Like the spider man's gran father  said,"With great power comes great responsibility".

Here some new test,
All the effects are intentionally exaggerated.
