Hi!
Here is my try. Please give me some suggestion. Thank U

well since i’m trying to learn python, i came up with the idea to do a script for a twisted torus, so i pick up the script of the torus from the blender scripts dir. and i’ve inserted a twist

Just stunning. Any chance of a tutorial or a screen shot of your set up?

[chela69]

gurus,
your twists have me in a twisted fix…i wanna learn how to model this…i am getting fan shapes and not what is shown above…where can i download the tutorial?

hi, try my script, it’s a modified script from the torus, then you just have to face loop select. That’s how i made mine.

hope it helps

[chela69]

hi paulo_gomes,
could u upload u r script somewhere else or here…the link above takes me to a page i can’t fathom…

here it is, is a copy of the add torus but with a extra field that sets the number of twists

Hi
Please comment on this, How much left?

[patricia3d]

Without Torus

[snelleeddy]

@kkrawal: when rendering something on a basic plan make sure it extends far enough to not see the corners (so having a horizon no probs but make sure its wide enough)
The texture based alpha value of the orange rings is kinda odd.
Let your name not cast shadows, it’s very distracting.

But the model is good.

[patricia3d]

Thanks. See another view

[samf]

It looks nice, but the original didn’t have one continuous ring. It has several separate rings.

[patricia3d]

@tcrazy
@samf

I think original also has same type of rings. Please tcrazy guide me about the rights. please show your model without torus.

[samf]

Here you go kkrawal. I had fun with the picture and highlighted each ring for you.

[patricia3d]

Hi samf
I think the actual idea that Torus should rotate on z axis.
Rotation you can see here.

Even though it is not that model, but I am happy that I have the opportunity to learn a lot of new things while creating this.
