Sine Ring Irregular

Ring created using Functy and printed by Shapeways. It was created as an anniversary gift for my wife to celebrate 12 years of marriage. I always wanted to create a piece of jewellery for her, but lack of dexterity meant I thought I'd never be able to before discovering 3D printing.

The image shows (clockwise from top left) the OpenGL Functy render, a 3D test print in WSF, the final ring printed in silver and a Blender cycles render.

The ring is constructed from 6 parametric curve threads each with a formula of the following form:

x = (8.5+((1+A*cos(B*4*a*(2*pi)))/2))*cos(a*(2*pi)),
y = (8.5+((1+A*cos(B*4*a*(2*pi)))/2))*sin(a*(2*pi)),
z = A*2.5*cos(B*2*a*(2*pi))+(1-A)*(1+A)*((2*B)-3)*2.5,
r = 0.5,
where A ∈ {0, 1, -1}, B ∈ {1, 2} and the parametric variable a ∈ [0, 1].

Amazing! The process is fascinating, as is the design idea. I always found designing jewellery to be especially difficult.

Thanks Esterhase. I'm really pleased you like it. My strategy when designing it was to approach it with no prior ability whatsoever. If I'd thought about it, it would have made things much harder!

Your comment suggests you've designed some jewellery, but I don't see any in your gallery. You've got some great line drawings though.

I decided that I was no good at it long before I joined DeviantArt.

I'm sure it's our loss then :(

Beautiful model and creation, and congratulations on your 12th anniversary. Best of luck to you both!

Thanks Nelson; I really appreciate you saying so. We've made it to 12.02 years now, so making progress ;)

Great job. Very intriguing design.

Thanks, I really appreciate you saying so. The design is actually a lot more structured (and symmetrical) than it looks in the images, so they're a bit deceptive.

I'm a huge sucker for symmetry in art. I don't know, it's just the way my brain sees things. I read somewhere that the more symmetrical a human face is, the more beautiful the person is perceived to be (in the eyes of others). So I guess it has something to do with human nature, and the perception of beauty, as our brain tells us it "should" be. The ring is absolutely beautiful to me, and I'm sure your wife was thrilled by it. How proud you must feel, having created it for her with yourself. Fantastic. Congratulations, by the way, and best of luck to you both in the future. By the way, the Blender render of the ring is excellent. Great work all around.

I meant to type "by yourself", not "with yourself". haha. You know what I mean I hope. I'll download and try you program in the near future. I'm amazed at your talent in being able to write your own application. I'm sure you will see huge success in the future. Just remember us "little guys" when you get all rich and famous. ;)

Yes, I remember the research about symmetrical faces too (possibly this?). That always seemed surprising to me, although there's no doubt different types of symmetry can produce beautiful results in general (as many of your pieces demonstrate).

I'm glad you like the ring though, and very grateful for your kind words. However, DA is a very humbling place to be when I look at what other people are creating; I'm just happy to have the chance to interact with such talented people!

Awesome. 3d printing amazes me. Very nice. Also your blender render came out great as well.
llewelld's avatar
Thanks Tony :) I spent ages trying to arrange the render to match the photo, and although it's not perfect and still a bit grainy, the accuracy Blender manages to achieve still amazes me. It's nothing compared to your renders, but I'm pleased with it nonetheless.

thank you. Just don't print any 3d guns. I watched that on the news today. People printing 3d guns. We are all in trouble now.

Wow. There always seems to be some way to subvert exciting technologies in depressing ways.

Well at least you were making a ring for your girl and not a gun to shoot down the block.
llewelld's avatar
True. I'm not sure the latter would have been too positive for my marriage ;)
