How do you read and write fbx files?

[li-ronghui]

FBX is the model file of Autodesk. I have sever questions about the 3D file and engine.
What method do you use to read and write the fbx file, and how do you generate the 3D dance movements in the demo?
Did you use the Unity or UE4 engine to generate 3D dance?
