it depends on what API your using and what model file type.

But generally you would use a thing called "key framing", for pre-coded animations, and any number of algorithms for real-time cloth and hair Ect.

Key framing is where in the model file there are several "key positions", for each movement. What the programmer does is when the model is loaded and displayed, the programmer fills in the gaps between these key frames with a computer estimation of what should go there. This is called tweening. This is useful because it gives the programmer the power to change the complexity of the transitions between key frames, to produce smoother or choppier animation.

It’s a pretty horrible explanation I’ve done, but here are a few resources for you:
