Wow Mike - you really take MoI to a whole new level!

BTW - If you post the obj I'll render a quick animation for you.

(long day...)


Thanks guys!!!
Can you see how I tried to use most of the new Version 3 features? ;-)

I really don't know how I managed to conjure up the idea of twirling an augmented NURBS surface, but I did have the general idea for the spiral-shaped rim in mind for a while. And up until the other day, I wasn't really sure how one could be made without a lot of surface editing with networks and sweeps.

The styling I came up with here for this rim has a really bubbly/swirly look. I took a look online of some nice rims out there and I have to tell you - the design detail that goes into some of them are a kin to designing jewelry, but on a larger scale. And then there is the structural and functional engineering!


> nice use of the "vortex" style radial flow!

Hi Michael - I think that the "whirlpoolizer" tool would be a wonderful addition to the Twist tool dialog. ...an extra button or check-box on the Twist dialog window.
I know they are different animals, but that might be a logical place to add it. More as a related option-switch to Twist - so it doesn't have to become a new dedicated tool.


> ..the tyre sent me racing back to my childhood and Meccano® kits.

They were called "Erector Sets" here. I had a few sets myself. The tire also reminds me of the many of the Lego varieties. They were coveted items among me and my brothers' Lego collections.


> BTW - If you post the obj I'll render a quick animation for you. Ed

Ed, I'd be very gracious to see a nice render of the model. Thanks! An animation? WOW!

I posted the .3dm file and some really poly-heavy .obj files in a .zip file placed on MediaFire...
But new .obj's could be made from the provided .3dm's if lower poly levels were needed.

If any of you are interested in rendering or just taking a close look at the model - download this zip file here:

Import. Apply 3 materials. Clcik render! (ooop's, 4 materials.....)

Nice but the rubber looks more like hard plastic than soft rubber.

I think it should look more like as seen on the attachment.

Peace,

Cool render!

Thank you Mike for this tutorial,hope you'll post on your website (it's easier for me if i need go there than explore all Moi's threads )
you technique can be useful in many other situations
I've opened your 3DM file than export in OBJ:i've found few areas where mesh is not regular (that's normal in complex surfaces)





this can generate artifacts when render so i choosed a complex lighting set-up:open space-sun-real asphalt floor and also applied a glossy white material for the rim
(i've just modeled 3 different rims and tires so i mounted my PIRELLI P7 on your rim)



i also did a close-up shot to see if appear any artifact:it's OK...although a not-perfect mesh
(maybe a stronger close-up should show the problem,but..you see the whole wheel or the car,not a little imperfection in a little area of the rim)



thanks again:M

Thanks guys!


Burr - Nice render!


Blade - Nice touch with the black coating and gold type!


M - I made note of that issue with the Fillet. I don't know if it's an error in the Fillet mechanism, of if the architecture of the surfaces I'm trying to fillet would naturally cause that type of discontinuity within the fillet result.

This might be a case where I would go back and replace the fillet with a series of blends.

Well, I think some kind of "match surface edges" tool would yield at least some help there.

---

re: fillet - that's probably the same issue mentioned here were closed fillets are not always smooth at their seam area:

I do have a fix for that coming in the next v3 beta, hopefully it won't have any other side effects, we'll see.

Amazing tutorial, I will try it as soon as I have some time.
Thanks for taking the time to share your knowledge!

From: Mike K4ICY (MAJIKMIKE)

Thank you Marc!

It's just part of my teaching nature to share these wonderful techniques with anyone who wants to try them.

I had the idea for this model on my mind, but it wasn't until I set up the tutorial that I knew I could produce it.
So really, I learn some new skills at almost the same time others can learn with me.

I can't help but be a cheerleader for MoI! Every time Michael adds a new feature, I find the program's ability grows

ten-fold.


Merci Pilou!

Merci pour vos bons efforts d'orner mon tutoriels avec une si belle langue!
(Mon propre français est complètement affreux, ou non-existant, et mes résultats de traducteur sont encore plus

mauvais!) ;-)

Je désire que beaucoup plus d'artistes et créateurs puissent aussi découvrir ce magnifique programme informatique.



Ed, just to connect your very well done animation and render to this particular tutorial's post, I'll link it here:

From: ed (EDDYF)


I animated Majik Mikes Turbine-Style Sports Rim from his OBJ file posted in his excellent tutorial at:

http://moi3d.com/forum/index.php?webtag=MOI&msg=5470.1

Video rendered with the Element 3D plug-in for Adobe After Effects. Total render time: Eleven minutes without motion

blur & depth-of-field. Fifty-five minutes as seen in the video below with motion blur and depth-of-field.

WOWWWW!!!! You made my model a movie star.
Awesome work Ed! =-D

I need to incorporate these renders in the tuts page soon.

From: ed (EDDYF)

Thanks for the comments Martin & Mike - Mike, link to the sources, or contact me and I'll email the originals in case

you do your own hosting.

I've never used Vimeo before and I'm happy how the upload turned out, especially because my mp4 video was not rendered

as large as the Vimeo screen. I was expecting to see some pixalation or artifacts, but it looks about as good as the

original - just a slight loss of sharpness due to the enlargement. I've always read that Vimeo video was higher quality

than You Tube - now I know.

i Ed,

I've incorporated a video window in my tuts page: http://www.k4icy.com/tutorials.html

Man, does that add the million-dollar touch!

Thanks again!

hahaha well you could have delete my "LoL" post :-)

But nice to see the posts back again,

Peace,

Hi Ed,

I realized your one render was submitted as a MoI post:
but I keep everyone done of my tutorials! ;-)

From: ed (EDDYF)

---

Here's my attempt at a render:




My focus was on the rim metal which is supposed to be a polished alloy aluminum with a ceramic glaze.

I made a quick room scene in MoI and render was done in Metropolis BiPT.

If I'm able to wait longer, I'll be able to take care of much of the noise.

And then there is this ... How close is this

Nice! A motorcycle with a hitch mount...

I could support an 10m-80m High-Sierra Screwdriver with an ATAS and 100 watts barefoot. ;-)

And do it in style!

---

Here is a unique object produced from a similar process.




This one started off as a Revolved-by-Rail cylinder made with a grid of 24x18 control points.
Some odd points were scaled in, while evens were scaled out to even the outside.
An inner circle was trimmed in the Z direction to 'gut' the inside shapes, then I used Twist.

Could be an old push-mower blade, or some kind of exhaust grate.

Here is a really nice render done by Ed Ferguson in KeyShot.
