elipsoid wire made out of elipses

Hello all,

 

I got request to do renderable wire made out of ellipses. It is quite difficult for me to name it correctly, let me try to enplane:

 

Imagine soccer ball, made out pentagon objects, instead I need sphere, made out circles. I know it is not possible to make it using exactly the same circles, towards top and bottom, it can have smaller circles, and after that I would squash using scale tool to make ellipsoid . I tried to model by scattering renderable circles on the sphere, but the problem was, circles are overlapping towards top and the bottom, which is not acceptable in my model.

Can antibody help me with suggestion, or tut how can I make such object.

 

Regards

I would also try to do it using a material (perhaps a clever gradient ramp set to radial), but if it absolutely has to be 3D I would UV map an image of the circles onto a sphere, then use the cut tool in edit poly to trace the circles, then delete all the unwanted polys, and give it some thickness with a shell modifier. It would make some nasty geometry, but should work.

Hi guys,

 

thanks for the post. In the meantime, I made sphere, squashed it to get basic geometry, and started to UVW unwrap. It is going to take me some time to unwrap, I "exploded" it in so many polygons (in uvw unwrap) to make it more precise, btw it is going to be my first :)

 

Only thing is if I do this way, I will not have a thiskness, unless I do some sort of displacement.

 

To adjust manually, edit polys, it will be very long, also it is not going to be precise enough. Only some elegant way may work effectivly.

i would defiantly give displacement a shot before exploding the thing, it would allow you more control to change later, if you explode to build, rebuilding and change would be a longer process I'm assuming....

 

I'm curious ....can I ask what this is getting built for?

I think your scattering idea in that first post was not a bad idea.

 

I just think if you use a Geo-sphere instead of a normal sphere then you'd already get closer to the result you want.

 

Here is a little test i did using a renderable circle, and scattering it onto every vertex of a geosphere. This way your circles will stay the same size all the way around.

 

Maybe you can perfect this.

Howzat Piet,

When I tried to do that I endup with some overlaping circles, the difference was I modified sphere to elipsoid, maybe thats why it did strange things. I like your model it looks almost perfect :)
