Ageia PhysX

I just rented Ghost Recon and I noticed that while starting,it said PhysX by Ageia

Is that right?I mean does PS3 has Ageia PhysX because I've heard that Ageia is only for PC and X360

So?

Does PS3 has it?

If not why does Ghost Recon shows it?

I think there are 2 kinds of PhysX, a hardware and a software solution. You can buy hardware PPU cards for PCs that calculate physics. You can also have the CPU do physics calculations in software.

Ageia was hoping to sell the hardware parts, but with today's CPUs and GPUs, they can handle it just as well. Havok is another software physics solution that many games use. Intel recently bought them. So, you know physics is here to stay.
