or openSource: https://collada.org/mediawiki/index.php/ColladaLoader
Google a bit a you will find a lot of material.
-Obj format is very simple but you can export only vertex, normal and uvmaps… nothing fancy.
-Fbx is very powerfull for export animation and is well supported by Maya, 3DsMax, XSI and motion builder.
-Collada is a Khronos very complete format (heavily sponsored by Sony) where you can export any kind of object, geometry, particle system… any thing you need. Is supported by a lot 3d authoring program.
I sugget to use the obj format first (to create some study program) and then move to a more complete format like collada.
The best of the best is when you write your own exporter for your 3d program.
