Cool! How do you deal with coplanar surfaces? Btw, I didn't know trilobites had doublet lens eyes. Amazing!

Thank you Tom! Physic is so amazing and funny. Thanks maxwell, I discover many things!
I had some problems with the coplanar surfaces. So I used the Thomas An glass technique.
Just moving a little the first lens inside the second one.

Glass materials from ior maxwell database.
Modeled with Rhino Beta.

Btw... Is it an option to adjust the quality lenses of the maxwell camera?

Hmm..this is suspicious. Thomas' method isn't suggesting intersection. I guess you should do it in matroska fashion.

Maxwell camera doesn't have chromatic or spherical aberration.

Can you elaborate? Google only turned up a file format...

But I imagine only one internal normal should be necessary to represent the transition from one material to another. Then exit normals.

I guess a tiny gap between meshes would be correct too as long as there were no intersections.

I used the third option.
Tom, do you think it will change something to make a little space between the 2 lenses?
Is the matroska not the same as the Thomas An technique. The Orange juice (or champagne ) is included in the glass, isnt'it?

Yes, it's why I remind. I'm afraid your method is not producing the correct look.

When you put space, TIR applies differently. Imagine a broken glass. It will show the crack no matter how tight you try to fit the pieces back.

This is the way?

Could you try in the way I've illustrated above?

Sorry Tom, but I have some difficulties to interpret your doublet lens illustrations.
Where are the limits of cyan/magenta lenses?

there is no magenta limit.

main rule is not to "double" faces as coplanar or make tiny infinitesmal gap or "crossing" two meshes as it is recomended in eg. vray.

just think of it like - there is no need to have closed geometry to get proper glass.

so second lens is "without bottom" cylinder.

Tested the 2 diagrams. Mine and Tom's version. (Some ondulation due to smoothing, I think)





Wich is the correct one

The second looks better to me.

Best,
Jason.

Very cool physics test!
I would expect the correct solution to be with a small gap between the lenses? I understand the problem when a fluid is in contact with glass, but two lenses....do they really polish them to match on molecular level?

And for that I thank you! I've spent a fortune on Canons highquality L-lenses and I still get annoying chromatic abberation that needs to be removed
