Eye Z

by NM-8 in Surfacing

PROCEDURAL EYE SHADER

Color the Iris, set its size, squeeze it if it's a dragon eye, set depth for a fake refractive effect and amplify the translucency of the Iris.This shader is meant to fake the complex geometry of an eyeball.
  • no Textures needed
  • no UV-Maps needed

FEATURES 


easy three color system

 



intuitive parameters for pattern adjustment





continous cat-eye effect

 


fake depth
fake caustics


iris/pupil: the radius relative to the eyeball surface in percent.

bump: bumpintensity of the iris-noisepattern.

vector: the space of the mapping. Input>TextureCoordinate>Object will direct the iris in z-direction of the object coordinates.



As the stretchvalue squeezes the eye, you can animate it to transform the pupil from round to slit, like a human transforming into a dragon.

The pupil is oriented into the Z-Axis of objectspace. So eyes will look "down" initially.

About the Creator: 

I am a 3D artist in the advertising & television industry for 25 years.
While working on projects and teaching animation at design college since 1998, i studied physics at the university of Vienna. That equipped me with a solid toolset of math to use in 3D workflows.

I started programming Blender add-ons and noding vector operations into shaders around 2012.

I love how Blender and Cycles offer a lot of opportunities to speed up rendering and fake depth into surfaces in many ways.
