Physx Replacement

I have recently changed the Physics Engine I am using to nVidia's PhysX as this had much better documentation than bullet and I didn't get much response from the Bullet Forums. The Bullet Functionality is still there so I could revert back if needs be. 

It has taken me a while to get PhysX integrated with my engine and also trying to maintain a generic structure. I finally got it working well and I have also implemented the one thing I was struggling to do with Bullet, which is callbacks. 

Essentially all they do is report when specified pairs collide so you can do some sort of game logic, in my case this was when the ball bounced with the floor or with an area that was out of play. Anyway enough talking here is a video of it in action: 

Okay so it isn't that impressive but it is the foundation for every other sort of interaction between physics objects and in game logic. Now that I have got these bare essentials in I can now put the physics stuff to one side and concentrate on some of the game logic. The next few things that are coming up are: 

• A game class that can send messages to the desired parts of the game and deal with keeping score and stopping and starting play.
• Shadow Mapping for the ball as it is hard to visualise depth at the moment.
• Mouse Picking to allow you to use the mouse to aim your shot.
• Animation to allow the use of a full character model instead of a racquet

Well there is still lots to be done and most of these things are pretty large pieces of functionality, I'm hoping to get at least one thing done very shortly as I seem to be on a roll at the moment. 

Cheers :)
