agrazdi,
Animator is not finished yet and still in Beta. Actually, it will be chargeable when more advanced.
There is also a difference between Simulator and Animation applications.
With Simulators, you design kinematic and physical constraints and relationship, and then you can freely move some objects or cameras, and record the effect as a video. Say, you design a car movement with wheels, and then you can drive it on any
road.So it is very powerful.
With Animation, you have to create your scenario, by arranging movements of objects and cameras along a timeline, regardless of physical constraints. Say, you drive the car on a given road. You get exactly what you want, but if you wish a variation, you need to modify the animation elements.
