Poser - OFFICIAL F.A.Q (Last Updated: 2024 Nov 18 10:25 pm)
Attached Link: Better Poser Planets with UV Mapper Pro
Here is a moon created with a sphere from UV Mapper Pro. A tut is available in the UV Mapper forum. After following the tut please come back here to finish up the Poser portion of the tut.Free men do not ask permission to bear

Except for the gas giants, for all intensive purposes, the planets are spherical - unless you are doing animations for NASA or something. Oblateness in most cases is negligible. But I would make Phobos and Deimos with extra special care. :)

Stretching the map at the poles won't do anything to fix it - the texture needs to be flat, max one or two shades, otherwise you get polar pinching. I'll show you :
(Sorry 'bout linking, tried keeping thread load size down :-))
http://spinner.northern-studios.com/imgs/mesh1.jpg - generic UVM sphere
http://spinner.northern-studios.com/imgs/mesh2.jpg - generic sphere stretch test(img, not native UVM)
http://spinner.northern-studios.com/imgs/mesh3.jpg - Texture from front
http://spinner.northern-studios.com/imgs/mesh4.jpg - Texture on top with polar pinching.
So the workaround I figured was to just use a bump-map for terrain variety and then put a one-coloured texture over it - like an icecap.
If the texture is flat-shaded on top you won't get this.

First of all - dont scream. Second - I assumed it also applied to textures you didn't download from a website somewhere - there is a discrepancy at the top of the moon, if you look closely - the texture gets narrower. The ice on Greenland is somewhat pinched (not squashed, pinched)- the isce on the southern tip doesnt look like that, if you compared it w. a map (And since I work with 3D military mapping applications, I know how Greenland looks with ice) Since we're not seeing eye to eye here, I'll leave you to it, and not ask any furher questions which may be difficult to answer. ~S

Fair enough - All caps means to shout in web/netspeak and I thought you were shouting at me. As for HTML - you may want to check this site out: http://www.davesite.com/webstation/html/chap03.shtml Actually - taking a peek at the moon map helped - I moseyed over to some of the NASA archives. They're squashing, whilst a lot of us others are actually stretching or reducing colour/density in that area. So I'll actually see what happens if I blow a texture up around the poles instead of making it as noisefree as possible ~S
I think a good place to start is a link like this: Map Definitions And move on to this link: Map Projections There is no mapping of a sphere to a plane that will ever be without distortions of one type or another. The hardest part here, I guess, is getting a planar map projection that matches the UV layout of the sphere. The one pictured above for the Moon appears to be a Miller Cylindrical projection (as compared to a Mercator where the poles are stretched vertically).
