Hi all, I modeled this basic eye shape in Silo today. I wanted to try for a
realistic look, building it at least *close* to accurate by using a separate
cornea w/pupil (just a flattened torus) actually set inside the bulge where the
lens would be.
I used an image_pattern to transition the transparent lens area around the
cornea into a solid eye texture on the eyeball itself. After a quick
fully-textured render I thought I'd have a go at doing a full close-up face shot
(since I'm trying to get better at UV mapping/texturing).
I remember admiring the close-up eye renders in a 3dRender.com lighting
challenge a few years ago so I went and found it online and grabbed the OBJ file
(http://www.3drender.com/challenges/). I brought it into Silo and deleted the
existing eye, inserted my eye, OBJ to PoseRay to Mesh2, and ended up with this
after about 6 hours of fiddling about with texturing and lighting and rendering
and gamma pre-correction of my UV maps and re-rendering (and thanks for the
gamma mini-tutorial yesterday Clipka and Alain, big help!).
No SSLT here, just a couple of layered textures using image_patterns to control
specular and reflection on the various areas.
Cheers,
Rob

Are you sure you did not post a photo by error? ;)
Only thing , it looks to me that the blod vessels are somewhat to
present, or to numerous.

I knew Pov was good, but that's a professional looking image that I'd
usually expect to see coming from Maya / PR Renderman or something... -well
done-!

Heh, yes I agree - looks like she's been up all night and is now seeing the
sunrise.
Actually, the blood vessels gave me some trouble. In the end I used the roots of
a weed pulled from my garden and photographed against a concrete floor. I
tweaked them a lot in PhotoShop and ended up with a spherical projection.
Here's the code for the eye texture (and accompanying maps: top is the iris
mask, next is color, next is bump, iris [of course] on the bottom).
#include "eye.inc"
#declare Eye = object {Eye translate <0,-1,-0.076621>}
#declare T_Eye = texture {
#if (Ambient_Occlusion)
T_Ambient_Occlusion
#else
image_pattern { png "cornea_mask.png" interpolate 2 map_type 1 }
texture_map {
[0 pigment {Clear}
normal {
bump_map {png "eyeball_map_bump.png" interpolate 2 map_type 1 }
bump_size 0.25
}
finish { reflection {0.1, 0.35 fresnel} conserve_energy
specular 1 roughness 0.001 brilliance 1
}
]
[1
pigment {
image_map { png "eyeball_map.png" interpolate 2 map_type 1 }
}
normal {
bump_map { png "eyeball_map_bump.png" interpolate 2 map_type 1 }
bump_size 0.25
}
finish { reflection {0.1, 0.35 fresnel} conserve_energy
specular 1 roughness 0.001 brilliance 1
}
]
}
rotate x*90
rotate -z*90
#end
}
#declare T_Iris = texture {
torus { 1, 0.5
rotate x*90
scale z*0.2
texture {
#if (Ambient_Occlusion)
T_Ambient_Occlusion
#else
pigment {
image_map { png "Iris.png" interpolate 2 map_type 0 once }
translate -0.5
}
normal {
bump_map { png "Iris.png" interpolate 2 map_type 0 once }
translate -0.5 bump_size 1
}
finish { specular 0.2 roughness 0.02 }
scale 3.1
#end
}
}
#end
object { Eye
scale 0.7
texture { T_Eye }
interior { ior 1.33 }
}

Thanks Stefan, I'm trying :)
I find that most CG people underestimate the power of POV. When I exhibit my
prints at art festivals, galleries, etc, someone "in-the-know" will invariably
come and ask me something like, "So which did you use for these - Maya or 3d
Studio Max?"
"Neither, they're all done with POV-Ray" I'll reply.
A blank stare of disbelief often follows, as if they're waiting for the punch
line.

LOL! Excellent! Both your work and your real world tale.

very good, except the skin around the eyelids look like plastic. Also,
too much veins for my liking. Quit smoking, dude... :)

Looks fantastic!
The only change I'd make to the eyeball is to the sclera - it's not smooth like
the surface of the cornea, but a bit bumpy instead. It shows up in the
reflection of the environment.
Cheers,
Edouard.

LOL, well she's apparently been up all night drinking and maybe smoking too, and
who knows what else. It's no wonder she's looking a overly bleary-eyed and
plasticine (especially without any SSS).
Seriously, point taken, I'll see what I can do to fix it :)
