Eye formation

[grit]

I would like to make perfect eye.


When I select circle and Render- >Line nova, it renders across all image and not inside the circle only.

How to render line nova inside the circle and how to make lines appear as on eye ?
They are not straight but somewhat wiggle.

I'm not quite sure, how you define "the perfect eye", but in case you want to achieve realistic results, I don't think you will get the best results if you try use procedural tools. You may experiment with Distort-Filters like "Waves" to get something that wiggle, and use Layer Masks to first render the line nova as it is and then make it a circle, but i doubt that this will ever look natural.

It will be far easier to simply paint the iris. Just look for a good brush set like this iris part brush set and use them to produce very good results.

Have fun!

I dont think there is a filter that will make this perfect eye you want.
It looks more like a painter job with the Smudge Tool or something and perhaps some Motion Blur.

Very quickly, an attempt:

1. Filters>Render>Cloud>Solid noise, and set large X and small Y to have mostly vertical wiggles
   
2. Filter>Distorts>Polar coordinates (make sure you have "To polar'" checked)
   
3. Color>Map>Gradient map to apply color (maybe add some contrast first)
   
4. Add pupil

Nice !

How do we get rid of the seam ? I know there was a way, but i forgot what it was.
Resynthesizer - Heal Selection doesnt give me very good results so far.

EDIT: now i remember. You have to make the Solid Noise seamless (check 'Tilable') !
Its not perfect but better.

   



You can also make a proto-eye with a gradient. Probably better made with selections, but still nice to know.

A possible way is to generate two eyes with seams in opposite directions and then blend them with an opacity gradient. If you are lazy you can also rotate/flip the eye instead, but the symmetry can be too apparent.
