very round smooth bevel

[walkinginspace]

I made this logo in PS. It has a very smooth almost bubbled out middle. I wondered what type of modeling techniques would be good to reproduce then LW. I've tried smashing spheres and stuff, but with no good results.

I am sure there are other ways, have you tried playing around with the magnet tool?

Ok here is what you do.

1) Take the image in photoshop and make it a grey scale.

2) measure the dimensions of the image in photoshop and make a polygon with the same dimensions in modeler (mesh it out pretty good).

3) You can use the greyscale image (lighter=higher, darker=lower) as a displacement texture map in layout. You high poly mesh with this displacement map should give you a near perfect approximation of the deformation you are looking for. Remember to save (transformed) to keep the modified geometry. Yo should then be able to slap the color image on as a color channel texture map - a little tweaking and it should look great!

Wow, that's cool...however with that example I am wondering if that blue band he has in the middle of the pic needs to be made white. Otherwise the displacement map from the grey scale image would have a nice round bevel coming out but then a deeper line running through the middle.

Yep that is exactly what happened, and all the little subtle color changes look like bumps and valleys. Hmmmm....any other ways?

there's gotta be some kind of way to model that sorta object. I've tried bevels which work great until you get to that middle area that needs to be round.....

Easy

Take a poly to match your example
subdivide it plenty
using your pic as a background, grab the points that are under the hump, starting from the level part to the highest, following the curves at the ends.
from side view move the set up a tad (depending on your scale depends on what a tad is), deselect the outer edge of points completlr around the full group, move up a tad again,deselect, move, deselect.
You should have about 4 or 5 rows of points to do.
you now have a bubble/ hump in logo.

did a quicky to show
yellow dots are moved dots
Only used 1 row and not likr last post with many
but you'll see what I mean.

If you go that route you can also use the contract or expand current selection too...it could save time.

I've gotten that far with it, it's a matter of getting the round and have a edge with defintion matching the sample........i'll keep at it, thanks for all the comments and if you have more keep'm coming!

Splines and subpatch is the way to go.
