Hello.
I'm trying to import a .dae file to my C++/OpenGL application. I've got per each <animation> five sources:
  1. Input.
  2. Output.
  3. Interpolation.
  4. Intangent.
  5. Outtangent.

One <sampler> and one channel. The question is: What does those five sources mean? What do they do?

Edit: Found.
