Physically modeled pianos basically replicate a piano using fancy math and physics an algorithm tells the computer what type of sound waves to produce depending on how you hit each key. This is also what your digital piano does, but again, your PC is a lot more powerful. Piano VSTs are essentially software that replicates the sound of an acoustic piano using one of two methods (or occasionally, both): modeling and sampling. What does a virtual piano do differently? Complement the setup with a good set of speakers or headphones, and you can have the most realistic piano experience short of buying an acoustic.
