Ok one last thing I forgot to mention:
Yes obviously nobody is going to be impressed by a Goraud shading demo in 2015, but this project has a second purpose. Metal, Mantle, DX12, GLnext, etc are The Next Big Thing™ and I wanted to get some practice in with them. A texture mapping demo won't light anybody's world on fire, but it serves as a good unit test.
The purpose of the Basic set of demos is more to serve as unit tests for porting the render pipeline to a new API. The Intermediate and Advanced are for future interviews. Also the basic demos could be used as basis for something more advanced IE skeletal animation -> skeletal animation with IK -> skeletal animation with IK/Cloth.
So yeah if the list of Basic demos look minimal, they're supposed to be. I just wanted to make a list of the bare minimum things to have so I could come back and expand upon them later.
