How do developers make Texture Atlas'? Do they do it by hand?
I'm using Unity3d, I think they have something about scripting an atlas, but I don't know how or understand to do it.
Can somebody explain the process of making Texture Atlas? If possible a way to script my own or provide a freeware alternative.
How can create texture atlas by hand via any of the third-party libraries available out there.
I would recommend this tutorial to start with: http://www.flipcode.com/archives/Rectangle_Placement.shtml
Later you can move on to the more advanced code: http://clb.demon.fi/projects/even-more-rectangle-bin-packing
