Hi Martin. I too found that ODE has a bit of a learning curve, even though
I've been a software developer for 18 years (not in game software, though).
I think that the best way to learn ODE is to build the demos that come with
it and start making small changes to them to see how they work. For my first
project I modified the boxstack demo to create a spinning gyroscope. (I
wanted to see if it precessed like real-world gyroscopes. It did.) You
didn't mention what your background is in math and physics. I recommend that
you get a book on math for 3D graphics programming and one on physics for
game programming. A lot of things will make more sense when you have that
I've seen it pointed out on this list that ODE is strictly a physics
engine--it has no support for other things one usually wants in a game or
simulation, such as graphics and sound. That's intentional--ODE's specific
goal is to model physical interactions, without making any assumptions about
how or where that model will be used. To create an application, additional
code has to be written that reads from ODE data structures and then creates
3D output using some other library (such as OpenGL or Ogre3D). (The ODE
demos use a component called DrawStuff, which is just meant for
quick-and-dirty testing, not for real applications.) Some people on this
list have suggested to other posters that they look for a game engine,
rather than a physics engine. Game engines have support for all of the
things you'll need to do in your simulation. One that is often recommended
is Irrlicht (http://irrlicht.sourceforge.net/).
When you finish your application, it would be nice if you would post a link
to it here as an example for future newbies.
