You model 3d things and composite them into the shots. A lot of considerations must be accounted for to make the end result appear seamless, blender is very powerful. Pixar's (yes, same as used in Toy Story etc.) Renderman is also free for non-commercial use and might be better for anime style, but VRoid might be the fastest modeler for non-experts like myself.
