Ball Collision

[sake]

Dear All,
I'm working on a 3d breakout game in C++, and I'm having a little trouble with the collision. It will detect that the ball has hit the paddle just fine, but after that, how do I determine where the ball should go? I've just been mirroring the direction

Ball.Velocity().x *= -1;
 

But this makes for very uninteresting gameplay. Any help would be very greatly appreciated.

The angle of incidence is equal to the anfle of reflection.

That is, a 30-degree angle from the paddle surface will be reflected at 30-desgrees from the paddle surface. After that it's a simple Cartesian plot.
