for my AR application I'd like to be able to easily import 3D models of different file formats like *.obj *.fbx and so on, so I don't have to manually convert them each time I want to load one. Has anyone used some kind of third party framework for this job and is willing to share his/her experience with it? What I'm looking for is easy model loading using few lines of (preferrably Objective-C) code with support for many popular 3D export file formats.
Personally I gave NinevehGL a quick look and I think it looks really promising as it has an Obj-C API and does the rendering as well but it isn't really actively developed anymore along with some downsides like missing armv7s support.
Thanks in advance
