View Full Version : Looking for eyeballs...

Anyone know where I can get a good pair of anatomically-correct, hi-res human eyeballs, with maps for spec, trans, refraction, bump, texture and anything else?
Not the real thing, of course. ;)
Preferably in lwo format, although I figure that's unlikely. OBJ would be acceptable.

Or better yet, a tutorial for making and rendering real good, convincing 3D eyes?
I'd really prefer to learn how to do it myself, but am not opposed to buying something if I have to.
I figure the modeling part can't be too big of a deal, but the rendering part seems to be a different story entirely. I have no idea where to begin. I have some UV mapped eyes and some textures, from a DAZ figure, but they're not cutting it. I'm not sure if it's that they're modeled inaccurately, or if it's that I don't understand enough about how light should interact with them. The textures aren't bad, but I'm not real sure how and where to apply the various maps, or even if the spec and bump maps are even worth using.

I imagine it's not a particularly easy thing, since it seems that dead looking eyes in CG are everywhere, but hey, it CAN be done, right?

There was a 'Realistic eyes in Lightwave' tutorial in 3d world about....ooh....8yrs ago? :D

Unfortunately I gave all of my 3d world, computer arts, computer arts projects and CGI magazines to a local college...all 300 of them along with the CD's.

There's a tutorial on Simply Lightwave but I don't know how convincing it is.

What's aggravating me is I know I've seen something for this before, but not for LW. Some video which I forgot to bookmark and now I can't find. It seems to me I've seen eyeball modeling tutorials too, but no go there, either.

Well the guy that did the tutorial was a regular in 3d World back in the day. He wrote a couple of books using Lightwave 5.6 and one of them was about character design. I'm pulling my hair out trying to remember his name but he might have some of those 3d world tutorials available online.

He had a beard and shaved head...does that help?....I'm also getting the letter 'B'...:S

Yeah, that narrows it down some, thanks. :D

The gnomon website has some free tutorials here, you just have to register.

They are for maya, but the principles should be the same.

Yeah, that's what I had seen before and forgotten where. Thanks!

Megalodon, thanks for the info, I'll check those out.

You might be referring to Leigh van-der-Bile's Lightwave 8 Texturing Book/CD. I have that too, but forgot about it. In any event, the eye texture is missing from the CD and in spite of that fact I asked her for it a few times, I never received a reply. No surprise there, really.

Can you find a cutaway anatomical medical drawing like this to use? Shows you all the structures you'd need to model for a real world eye.

Hi IMI

If I remember correctly, there was a female head tutorial in Dan Ablan's Inside LW 8 book, If you don't own it and if Dan's not around, I could check the included CD and post the eye ball object here

Let me know if you're interested :)

Haven't tried the scale here, but this should help with indices of refraction:

It was Bill Fleming and I've just gone through the first sixteen issues of 3D World, when I was dep ed and then ed, but can't find anything by him. Perhaps ask the new ed? He's on here somewhere... ;)

Bill Fleming's books "3d Texture Workshop - Painting Hollywood Creature Textures" has a nice chapter about painting realistic eye textures. And it comes with the Freaky Frank head which includes the eyes. A bit of an oldie, though (2002). Whatever happened to that guy?

A good tutorial on creating realistic looking eyes in Blender can be found here:
http://vimeo.com/groups/10834/videos/2830890

I would add a bit of sub-surface scattering as well.

Same principles and steps apply in Lightwave.

I found just one article about creating realistic eyes in 3d World Magazine. I scanned the article (just 1 1/2 page).

BILL FLEMING!!!

That's not actually the article I was referring to but at least I can sleep better tonight.

He did several tutorials including a wierd spaceship made from junk with a large sack wrapped in a rope net. It seemed to have a lot of Lightwave stuff in the first year or so. It was around the same time that I was reading CGI magazine too so it's possible that it was in there but I'm fairly certain that it was 3d world. I suspect that it's the same tutorial from the book that Rayek mentioned.

or hit www.sharbor.com and lookup Dosch for eyes.


Cheap libraries.
So why reinvent the wheel?

I long forgot about that. Yeah I do have the book and the DVD, so I'll check it out. Thank you for offering. :)

And thanks to everyone else for all the suggestions and links and resources too. The eye part of my project is on hold as I work on other things, but I'll be getting to it soon enough. I'll post some renders if all turns out well. :)

EDIT:
Correction, I just checked and that was Inside LightWave 7 that had the female head tutorial, which I also have. ILW8 had the Ogre tutorial, along with a 'toon giraffe, a cell phone and a Corvette. I have that one too. That was the first one he included video tutorials with.

Both ILW6 and ILW7 had the head tutorial.
