Title: Making a ring help!
Post by: phantom king on March 12, 2008, 06:16:34 pm
Hey guys! Gotta question ;D, how can i make like a circular(more like hexagonal for low polygon count) ring? where there is a hole in the middle.

thanks in advance =P

i think there's a torus plugin or something that makes a shape like this, try google, it's a great friend when ur looking for stuff like this

i don't know much about installing plugins, but i'm sure there will be documentation somewhere on the download or website

if you want to do it w/o plugin you can make a thin rectangle using splines lathe it and delete the faces on the top like this.... (http://C:\Documents and Settings\Matthew Sutton\My Documents\animv095c\ring.jpg)

well,what to expand on......what i did for that is did whay i said,but then i noticed that there was no hole, so i deleted the center point on top and bottom in wireframe.sorry i don't really know how to make pics of wireframe,splines,etc. if i could i'd make a torus tutorial in the mean time i'll try to email the torus in the model database in the resources.

I recommend lathing, it's the easiest way (i think Torus plugin is not exactly what you need...)

see lathing in the manual (http://www.anim8or.com/manual/3_object_editor.html#lathing)

yeah....i dont use plugins.i tried it once,they aren't as awsome as it seems.first of all, it's like using someone else's model, and what skill does that build if the model is already made for you.

My thoughts on your dilemma ,
1: pull ou a cylinder make it 18 longitude, untick cap start and end then convert to mesh,
2: go point mode, delete all the points except last segment. now you should have a ring
3: select face mode....multiselect all faces, click shell tool and drag out to make some thickness
4: select edge mode ....multiselect top and bottom edges of cylinder seg....click bevel tool and drag  to bevel edges of ring
5: subdivide ... presto a ring... apply gold texture ......somebody`s wedding?
took a couple minutes ... this took longer to write and post

Another way:
1.  Go "Build>primitives>N-gon" and change the 'Value' to however many sides you want for your ring.
2.  In object edit mode use the "Add N-gon" tool (G), drag the tool to create a ring of the size you want.
3.  Go "Build>Extrude" and change the length and segments as you wish (If you want to keep it lowpoly you'll want the segments to be 1), also be sure to check the proper axis to extrude on.  If you create the N-gon in the front view, you'll extrude along the z-azis, if you did it from the top view you'll extrude on the y-axis.  Lastly make sure to uncheck "cap start" and "cap end".  Then, in point-edit mode use the shell tool on the object and drag too the desired width.

Hihosilver: Nice, wouldn't have thought of that.  I would create a cross section of the ring, using a stretched n-gon or manually drawn polygon, shift it off the axis of rotation, and lathe it.  Quick and simple.  You could also create an extrusion from the polygon and then use a bend modifier to curl it up perhaps, in much the same way a ring is made in real life.  I dunno, I would have to experiment with that.

Ensoniq5:  About the curling method:
It is possible, and it's been done before.  I haven't heard about it being done for rings, but that's one way of making a tire with treads.  Some people model one flat section of the treads, then copy and paste in a long line, joining the solids and merging the points.  Then they use the bend modifier (you have to be very exact) and create a bend of 360 degrees.  They then merge the points where they meet, and have perfect treads!

Alternatively:

:) :) :)

Make a cylinder of the appropriate dimensions.
Convert to mesh.
Select top and bottom faces (caps)
Indent faces.
Hit bridge command (= button)
Subdivide.
Voila.

Mind you a cylinder is predefined primitif so you should not really use it....

ooo so many solutions :D, ill try them all out and see which fits best! Thanks guys! :D

Or build primitives....Ngon    create your ngon...Ctrl C   Ctrl V..make the copy a bit smaller ( scale) Join Splines...Fill.
Title: Re: Making a ring help!
Post by: im not a people person73 on March 13, 2008, 07:27:41 pm
that way seems the simplest.
Title: Re: Making a ring help!
Post by: hihosilver on March 13, 2008, 09:11:37 pm
OR!
haha, so many...
Do what benzjie said, but instead of filling at the end, extrude the splines, make sure the start and end ARE capped this time. voila!

Haha! I have been watching this thread with great interest as usually requests for items like this have usually been answered with the stock reply "Read the Manual" so it seems hopefully, times they are a changing.

I tried andrews method and found that one to be pretty quick!

so this might be another bit to go in Dotan8 !!

Heh heh.  I think, at times, these threads stop being about answering the OP's question, and start being more about showing off one's modelling kung fu!  But hey, it's great, everybody learns something new and we are reminded, again, that there are often many approaches to the same result.

make 2 Ngons with 60 sections, have the first one be the size of the ring. the second one should be the thickness of the ring. select the smaller Ngon go to  Build > Extrude and select "path" in the axis selection. click ok. select the larger ring. then add a material/ texture you can get a good result. here is one i made.
