Ring modelling question

[moka.studio]

Hi guys,

Can someone help me out? I want to model a ring with HyperNurbs. It has to look a bit like this ring, only without the diamonds. I just want to know how to model the ring.

As I am not that advanced in HyperNurb modelling, please explain thoroughly.

Thanx

Hi Lisette, here are a couple of tips.
import a 2d reference image, as it is hard to keep continuous circular forms with HN without references.
You could actually model a quick mockup with a bi-rail Sweep Nurbs
- make sure you keep a clean, 'flowing' geometry, avoiding triangles
The cage form should really apprximate the final H form the more detail you apply.
-Avoid setting HN weights until the end ( to tighten up a part of the geometry, you can make a loop cut close to the edge loop in question)

I would start with a torus. (objects>primitive>torus) ring segments to 48 (a better circle) and pipe segments to 8. This 8 gives you roughly two rings of polys on top, two at the bottom, tow inside and two outside.

Make editable (press C)

Create a Hypernurbs and place the torus as a child under it.

Now, in polygon mode, take the select loops tool and select the two outer rings (use shift to select the second one). Scale tool and push them in by dragging your mouse to the left somewhere on your workspace.
Select the two inner rings with the same tool and scale them outwards (drag the mouse to the right).

This looks a bit like a ring. But the inside is too rounded. Therefore go to edge mode and with the loop selection tool select the central ring of edges on the inside. Scale it by dragging to the right so that the inside becomes as good as straight.

Back to polygon mode, loop selection, and select not a loop around the ring but a vertical loop. Take the live selection tool and select in its properties (drop down) soft selection. Leave linear, but set radius to some 400 (if you didn't change the initial values that is). Now scale down, and you will see how you get a gradual scaling.

This gives you the basic shape of the ring.

[ooo]

Another possibility would be to make a boolean object with the torus and a cylinder. See the screenshot. Choose a high segmentation for the torus and the cylinder and you get a smooth ring.

Cheers, odo

Maybe this Link can (http://www.cinema4d.nl/phpBB2/viewtopic.php?t=3998&postdays=0&postorder=asc&start=0) can help ? plz show some respect to the dutch C4D members who try'd to help you as much they could.
There's also an image that explain the basic how to build you model :

Yes Hypernurbs will do it :buttrock:

Looks like the question has already been answered on another forum?
This is specialist shopping.
Last time I invest my time.

[Rich-Art]

Yes indeed.

How many examples do you need?

Hi, Erik,
Thank you for posting that very detailed answer.
I'm just starting to model jewelry in C4D and that is exactly the kind of thing I need to know.
You answer is valueable to all the forum visitors that don't frequent the Dutch site.
Thanks again,
larry

Hi Erik,

Thanks a lot for your help! I will go and check it out! I'm sorry you had to see the childish actions of Luckske and Richart. Recording to them, I'm not allowed to go the other forums to get better (read: better explained)help. Again...thanks! This will be great help to everyone who is going to design jewellery.

Regards,

Lizzy

Luckske and Rich Art are valued members of our Cinema family. Please don't call them childish. No need for that. Everywhere you asked, you got help. All this help together should be enough to get you started. You will have to take that first step yourself.
Please show the results of the various techniques people explained to you.

Glyptic: I would try the other methods too. There are several, and each has its advantages and limitations. Because it hadn't got to be exact, a torus looked to me ok. But for exact work, based on sketches (I love Wolfers' sketches!), other techniques could prove far more interesting.
As Moka-J wrote: do try out the Hypernurbs weighting (in the properties of the live selection tool) on points, edges and polys. And play, have fun with soft selections.

Erik,

I don't think it is very decent to badmouth somebody like this in public in my opinion. There was no need for this to happen.

I'll try your technique and post the result.

Lizzy

@ Lizzy : The only one who's pathetic is you ! you logged in with a new username to get the attension from a starting c4d user , i guess you are using +- 2 or 3 years cinema4d and we expect that you at least should know the c4d basics.
You can call us both childish but we and a lot other c4d member know better we like to cal you lazy insteed of lizzy (get the picture ?) .
suddenly you try to get us in a bad daylight but i don't care , the most important thing is that a lot c4d members know that you are pathetic , lazy and at last verry stupid.
like i told before : look around foor another hobby if it's to difficult to understand.

Sorry to other members who have notting to do with this but its getting enoying for others who like to spend energy in learning c4d.

Greetz, Luckske

Thanx for your response, i think it's just frustration c4d won't work for here : so someone has to pay for it.
But we have a limit of patience if you understand what i mean ...

[Glyptic]

Yes, Erik, I intend to play *a lot*.
I'm used to Rhino/NURBS modeling, so C4D is quite a change. But I anticipate using both for my work.
Thanks again for your post. It was very helpful.
Now excuse me, while I get out of the way of lively exchange going on.
cheers,

Please solve this dispute through msn or such. Or even better: just leave it be. Regardless of who I think is right, because this isn't getting anywhere with everyone needing to have the last word about it* (over and over again).

Please :scream:!

*Please ignore the paradox :D.

[AkaKico]

Erik. it was great of you to answer this question in such at detailed manner. I can't believe that I'd never used soft selections before. Wow... I'm ashamed that I never noticed them, haha. Awesomeness. Just wanted to thank you before this thread closes.Later!

[lisettevdmeij]

I'm sorry you guys had to see this. I haven't asked for this public humiliation. I just want to design...plain and simple. :)

Whith all my respect for your tribute in c4d, i would end this enoying conversation because it has no use.
The only thing i don't understand is : after all the tips and tricks she get from a the c4d users she learned nothing, i never had any words with you because it don't needed.
But plz admit what she's doing right now is pathetic, over and over again trying to get info from others who are so friendly to spend there time and for what use ?

[lisettevdmeij]

Yay!! I'm starting to get it! It looks like crap, but I understand the proces so much more....Erik, it doesn't look as good as yours, but I'm getting there! Thanks A LOT for the help! I've learned about the selections a lot!

[frinkky]

Well, I hope noneof this ended in fisticuffs :D

I for one learnt at least one thing from this forum and that was the existance of soft selection, a tool I could have done with from the days of v5 SE.

Thanks.

[lisettevdmeij]

Here is a better one. This is AWESOME! WHoooo....I'm so excited! http://img.photobucket.com/albums/v54/lisette_vandermeij/sweet2.jpg
