Thanks to you, Zom-B!

An ISL grid shader, useful for testing uv sets...

Awesome to see your progress Juan, and thanks for sharing it with us! As Zom_B said, great to see people jumping in ISL...looking forward to seeing more experiments!

[juan_irender]

Thanks Polinalkrimizei!
I´m eager to have some time to develop more shaders and to put more examples here.

Ciao,

Hi all.
A new pic: the stucco shader in action, in a more complexly lit room. Besides the Jotero Ajax, which sports an ISL 3d noise shader, a Perlin synthetic marble. This material has no SSS, although it may seem like it has some subsurface scattering.
The scene was resolved with bidirectional MLT in 5 hours aprox.

Ciao.

Very cool stuff !

[juan_irender]

Well, here I am again .
One cool new feature in Indigo (3.6.14) is the possibility to load textures in the ISL code window, so now you can access to these texture values from ISL (thanks Ono and Indigo team!).
A fast and easy adaptation to use this is an ISL marble shader that now uses a pic as a table lookup to calculate the color of the surface, instead of a simple value.
I left two examples of this shader in action.
Other inmediate use of this technique would be a wood shader...

Ciao.

A very simple ISL wood shader...
Material exponent is also procedurally controlled.
RMAN companion still rules!

Ciao.

[juan_irender]

This is an experiment with a displaced surface material, managed from ISL.
Color and exponent are also ISL computed.

Ciao.

Not bad. I am still waiting to see a really convincing wood done with ISL though!

Hi Ono.
I have very good Wood RMAN shaders (not mine), but the code is complex and the adaptation to ISL is not a trivial task.
I will attempt in the near future...

Ciao.

A much better wood shader
Another RMAN shader ported to ISL!

Ciao.

[CTZn]

yup, better.

[juan_irender]

Thanks CTZn, I´m working now on a better Wood surface shader, devised by Larry Gritz some time ago...

Ciao.

I've seen that image from cycles using OSL. Not bad

I'm just pasting here my own research on 2d woods, RC5 is much more versatile that the screen caps suggest. Granted, his shader is a 3d shader from the mentionned source.
