Torus

Hello,

I need to make a torus, but I'm facing two problems.

1) The radius of the circles.

The radius of each circle is the distance between the center (on the axis) and the divisions of the curve.

The circles do not intersect with the points.

2) I need to add perpendicular ellipses. I thought it would be helpful to add pframes, but it didn't work for me.

Any help would be helpful.

Thank you

I think there is a readytouse-torus function in lunchbox.

You probably could use uv-data to get a wireframe.

Not sure, if this is the way you want to go though.

Best,

Phillip

And if there isn't, a torus is just a circle swept along another circle, or a circle revolved around an axis, or loft though a couple of rotated circles.

Then extract UV isocurves from the surface as a wireframe, as phillip suggested.

Hello guys,

Thank you a lot for your help, really.

It worked.

I want some more help if you could.

I need to make attractor points, which will affect the division points on torus to come closer.

I also need to have those attractor points to affect the division points and move them in the direction of the Attractor point to the division points. As it moves to push the near one away.

Any idea of doing it? Thank you very mych!

Hi, something like this maybe? This one doesn't use lunch box to generate the toroid, it does however need a gh user object from my blog --> point attractor

you can also try Michael Pryor's grid pinching to achieve similar results..

Regards,

Hi, thanks for your help.

I followed your example, and used your tools, really helpful! I'm facing a problem in the part of adding the curve to the new points came out from the attractor. I'm having a unified curve a horizontal connected with the perpendicular one, as you can see in the image.
