Sergio Posted June 5, 2007 Share Posted June 5, 2007 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 Srdjan Link to comment Share on other sites More sharing options...
IHAB Posted June 6, 2007 Share Posted June 6, 2007 you can simply do it by assigning material to a sphere Link to comment Share on other sites More sharing options...
Mechadus Posted June 6, 2007 Share Posted June 6, 2007 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. -Nick Kropat Sr 3D Artist http://www.3Dwebmedia.com Link to comment Share on other sites More sharing options...
Sergio Posted June 6, 2007 Author Share Posted June 6, 2007 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.

BrianKitts Posted June 6, 2007 Share Posted June 6, 2007 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? Link to comment Share on other sites More sharing options...
Sergio Posted June 7, 2007 Author Share Posted June 7, 2007 Hello BKittsARC, Thanks for the screenshot nice to see other peoples techniques. The idea for this is to be glass support, from the outside. Regards Srdjan Link to comment Share on other sites More sharing options...
sterealkey Posted June 7, 2007 Share Posted June 7, 2007 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. Link to comment Share on other sites More sharing options...
Sergio Posted June 7, 2007 Author Share Posted June 7, 2007 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 Regards Srdjan Link to comment Share on other sites More sharing options...
sterealkey Posted June 7, 2007 Share Posted June 7, 2007 Thanx for the almost perfect comment Maybe if you first scatter, then convert to editable poly, and then scale or FFD it to be elipsoid. That might work Link to comment Share on other sites More sharing options...
Sergio Posted June 7, 2007 Author Share Posted June 7, 2007 Howzat Piet, that is very good idea, but the people want to have circles on elipsoid, and using your, must say very good idea , will make circles ito elipses Regards Srdjan Link to comment Share on other sites More sharing options...
sterealkey Posted June 8, 2007 Share Posted June 8, 2007 You have a point. I hope you get it figured out, if you do, then please post the result here and tell us how you did it. Good luck! Cheers, Piet Link to comment Share on other sites More sharing options...
