3D rendering app for IOS or Windows RT (Surface)

Hi all,

Can anyone advise me if there is a 3D modelling app out there that lets me create renders for export as .OBJ, .STL Ect?

I have been looking via both app stores but can't find anything..

If anyone knows of anything please let me know

 

Bump, still struggling.. It's almost like one doesn't exist

 

You won't find one for the Surface RT, I retired mine long ago for a Surface PRO due to its limitations. Here's a little list for iOS though http://www.businessinsider.com/making-art-on-your-ios-device-part-3-3d-modeling-2011-8?IR=T

 

That article is perfect and just what I've been looking for! Thank you so much
