How to create a perfect geosphere in Maya

BARDLER

I made a regular sphere and a geosphere in maya, but the problem is the geosphere is not perfectly spherical. As you can see.


It is a little oblong shaped where the original cube use to be. Is there a way to fix this? Or a way to create a perfect geosphere in maya?

I did find a script that let me create an Icosahedron, like so.

It requires like half the triangles to hold the same shape, but it is a pain to UV map because of the shape.

Any thoughts?

do the subdivided box method, than apply a sculpt deformer and make it just about the same size as the sphere, than delete history, doing this more or less fakes a max spherify.

Don't you have Zbrush? You can project the geosphere over the regular one.

I'd suggest you the old polyShrinkWrap plugin for Maya - http://www.creativecrash.com/maya/downloads/scripts-plugins/modeling/c/polyshrinkwrap - but unfortunately, it seems it runs just on Maya 2008, win32.

The project thing gave me an idea, and I actually used 3D coat to get the results I needed. If anybody needs to do this then just follow this.

1)Make a sphere in maya and smooth it a couple times to make sure it is perfectly round.
2)Make a geo-sphere in Maya by smoothing a cube a few times.
3)Make the geo-sphere a little bigger than the regular sphere, and export both as OBJs
4)Import the regular sphere as a reference mesh in 3D coat.
5)Import the geo-sphere through the retopo menu. When you do this it will ask you if you want to bind the geometry to the reference mesh, hit yes.
6) I had to clean up a couple missing faces, but besides that it should be good. Export back out, and save for later use.

Results. I made the geosphere a tad larger so you could see it.

I would think there's something similar in 3ds Max, but in Blender all you have to do is-

1) Create a cube and subdivide it (creates the equivalent of a geosphere)
3) Use the 'To Sphere' command to make it a perfect sphere

Does maya not have a built in shrink wrap option?

Yep, you can use the Transfer Attributes.

Like :

i use transfer atrributes for that like Froyok.

to make a smoothed cube perfectly round use animation tab->create deformers->Sculpt Deformer. You might need to scale the Sculpeter node to fit to your base object. And delete history if you're done.

JR

Oh, that Transfer attributes tip is really good! Thanks guys.

ya just make sure to delete history after you use the deformer or the transfer attribute method, since once you delete the sphere you used to conform to, the subdivided cube will go back to it;ls old shape if the history isnt deleted first

Oh perfect I did not know you could use transfer attributes like that. Thanks a lot! Much easier than going to 3D coat XD

ya a feature i maya i miss in other applications, i use it a lot when UV identical obejcts, so instead of having to delete a bunch of things UV one and copy back you can just transfer UV between objects with the same topology too with that too, amung a few other cool uses.

It is amazing how some things in Maya work so well, and are perfectly designed. Then other things are just so god damn retarded lol.

ya, out of the box maya can be pretty shit at times, i wrote thousands of lines of code for maya to scratch my various itches with it, and without that i think i would be rageing half the time using it.
