@bacon_chaney I appreciate that. It was an expected loss but its never easy:(. I can only take some comfort in the fact that its what my grandmother wanted. @Sam M: Thanks:). I’m fairly new to blender, but I’m learning with each render.
Can’t sleep because of this stupid cold so might as well blend at 2:00am.
I had tried finding a good way to make irises but came up empty until I was working on my nebula tutorial(I’ll finish that sometime…really I will, I just need to add screenshots). I was looking for more uses and made a wormhole. It kind of looked like an iris so I went from there. Volumetric point light test becomes nebula, nebula becomes wormhole, wormhole becomes iris?. iris1.blend (371 KB) The first one or close to it irisbc.blend (391 KB) Multiple colors
ah very intuitive, i can see why you used one to make the other, looks like it would be pretty convinving as it is gives alot more colour variation than just adding cloud textures to a plane, always looks a bit flat. this at least gives the impression of alot of depth
I really wish I could get a better picture of my eye, because it really does look a lot different in real life…After reading (some of) that wiki page, I noticed one main thing. That Although Brown eyes are the most common, and Green eyes are the least common, that the combination of Green with Brown/Red is the most common combination. Another thing is, that genetically I am a freak! Blonde hair, Brown/Green eyes, tall, wide shoulders. While everyone in my family has Dark hair, blue eyes, are short, thin shoulders. Wierd…
I wish I had a better camera, but unfortunately everything here in Italy costs HEAPS! 150 euro for a terrible camera, while back in Australia it would of cost me about $60…Well, only 2 months left here.
Havn’t had a chance to check those .blends but I will after these last 50 frames have rendered out…only 6 hours left XD
Hazel
Hazel iris (Inner brown and outer green ring)
Hazel eyes are due to a combination of Rayleigh scattering and a moderate amount of melanin in the iris’s anterior border layer.[7][25] Hazel eyes often appear to shift in color from a light brown to a golden-green. Hazel mostly consists of brown and green. The dominant color in the eye can either be green or light brown/gold. This is how many people mistake hazel eyes to be amber and vice versa.[48][49][50][51][52][53][54] This can sometimes produce a multicolored iris, i.e., an eye that is light brown/amber near the pupil and charcoal or dark green on the outer part of the iris (and vice versa) when observed in sunlight.
Definitions of the eye color hazel vary: it is sometimes considered to be synonymous with light brown or gold, as in the color of a hazelnut shell.[48][50][53][55] - Wikipedia
haha i thought it was hazel looking at the photos, sorry i should have explained myself better but im glad wikipedia helped haha are you going to wait till you get back to oz to take some photos then?
im really interested to see how far you can take the procedural textures and whether you could rig up different combinations with scripts etc
I still learning Blender and don’t have any experience with scripts so I’m curious to see what you more experience users can do with it. If you like you can post your results, .blends, and whatever else in this thread all you want.
Nope, nothing that fancy:), increased mapping size on x and y to shrink(decreasing z to stretch didn’t look as good) it for a more fibrous look. Scaled back cylinder to smooth transition. Here’s the blend…I think irisdblb5.blend (385 KB)
I was going to suggest scaling down one end of the cylinder, looks like great mids think alike eh?
Also, something that I did to get some different results again was scaling down the end of the FIRST tube, and the end of the LAST tube. got a nice look that way too. It would be nice to see if this is possible to do without volumes, because Volumes are a real pain at render time…But that is my complaining not your good work’s fault
Still can’t get a nice pictue of my eye…Might just colour doctor that one and see what happens.
@Wefyb you can post it if you want. Changing the inside diameter and shape is how I got the cat eye. Doing it without volumes would be nice, but everything I have tried looked really flat and depth-less.
Arman’s and the ones you guys posted are surprisingly good. Its quite difficult to get good iris photos unless you want to spend some serious cash or DIY build a special rig. http://www.milesresearch.com/
haha im not surprised, its difficult not to block your own light or have it washed out by a flash or reflections. its good to see how the thread is blossoming at this rate there will be quite a few resources for the community by the end of it
hope you don’t mind thought I’d add this for comparison. you can play around with the geometry and textures for different results. also you can add multiple materials for better control.
