Autodesk fbx SDK Program (2)

This is the second learning Note of the Autodesk fbx SDK. The following Chinese characters are translated from the Autodesk fbx SDK program.

In the previous article, we talked about some basic operations of the fbx SDK, creating fbxmanager, and writing our first fbx SDK example.

Today is the second part of the fbx SDK guide. How can I create an fbx file converter?

Convert fbx to the Dae and OBJ formats! Convert fbx binary to text format!

Knowledge points of this article:

1. fbxmanager creation and destruction

2. Create and use fbximporter

3. Use of fbxexporter

4. file formats supported by fbx SDK

Official example running effect:

I don't know whether it is MFC or. NET. I don't know either of them, so I still write a console ......
