What are some of the key benefits of using inverse kinematics over other animation techniques, such as forward kinematics or procedural animation?

@bbcd0921, I believe inverse kinematics is used to answer the question "If I want the final position to be here, where should all joints be in between the start and the end of the animation?"
Forward kinematic is used to answer the questions "If the joints are here and moving in a certain direction, where are the joints in the next frame?"
Procedural animation is a technique of animating the object, it uses both forward and inverse kinematics to generate the animation.

@bbcd0921 It also lessens the work for animators for a variety of scenarios to make their workflow smoother. With projects with dynamic body positions and environments (such as video games) inverse kinematics can significantly reduce the labor for animating things as simple as walking up a flight of stairs to picking up an object from multiple angles.

@bbcd0921 the benefits were mentioned, but it is important to note that there are some tradeoffs when using inverse kinematics. Though it speeds up computation, the method is unstable and can result in getting no answers or multiple answers which is typically undesirable.

Following up on @waleedlatif1, it's true that implementing inverse kinematics can be problematic, especially in robotics. Trying to get from one point to another in the reachable workspace can have multiple solutions, which leads programmers to solve another problem - which path is best? Usually the shortest path works well, but if there are obstacles or constraints in the way, it can get tricky to use inverse kinematics to determine the path.
