Hi, what are the (binary) file formats that are suitable for mobile devices like the iPhone, Android, etc.?
From my understanding, the Wavefront OBJ format seems to be the best choice as it is free and easy to implement. However, since it is basic text file and lacks support for shaders, I am thinking if there is something similar but with extended support, i.e. a compressed OBJ file with some additional containers defined for shaders?
I have thought of COLLADA, too. But in their web site they say it is more suitable for an exchanging purpose amongst 3D editing software rather than for end-presentation.
What do you think or best, what are you using?
Comments highly appreciated.
