Hello. I want to show Blender model on screen. I know how to make own Blender exporter to export vertices, normals data and I know how to read it in C++. I know I will have to do animation some time. How to do this? I know skeletal animation would be best, but thats some tough stuff. What are alternatives? What are other ways of animating objects? (humans,animals :>)

Well, I'm not really sure, but the only other way I know is 'vertex' animation. But that just "over-kill". I'll take 'Skeletal' animation any day.

If you're using Blender, you should stick with Skeletal animation. It's data file is berfect for it (in my view anyway).
