Information about Stepmania game engine

[SkuAir]

Hello all,

Maybe i'm a noob at searching the forum but i did't see a thread about it :rolleyes:

I'm new in Stepmania world and i'm interested how does it work.

In fact i would like to have some information about the Stepmania game engine.
I saw in the source code something about "Rage" like RageDisplay, RageInput, ...
So i think it's the game engine to manage all about graphics, i/o, ...

Someone can tell me more about it ?
Is it a game engine just made for Stepmania or is it used in other projects ?

Does a documentation exist ? I saw the class documentation, and i saw all the Rage(...) classes but i don't understand how does it work...
If Rage manages graphics, how does it work : it calls OpenGL librairies or Rage uses its own librairies, is it like a 2D or 3D engine ?

So a lot of questions to understand better how does it work :)

Thx all !

Rage was written for StepMania, however it should be reusable in other projects.

It uses OpenGL (and DirectX is also available on windows).
