Which technique will the gaming industry use for effortless interaction among in-game characters?

a. real-time fluid dynamics

b. quantum mechanics

c. 3d fluid mechanics

d. real-time static friction

e. real-time inverse kinematics

E. real-time inverse kinematics

The technique is E. real time inverse kinematics.

The real time inverse kinematics is used in stimulation of figures in animation. This tool lets the figure to move with 100 degree of freedom which lets the figure to the animator to set the perfect posture. It uses algorithms where the animator sets certain parameter and computes the algorithms and checks whether the figure is acceptable.

This tool is based on the motion of the robots where the motion of the robots is captured and used to set the parameters for the motion of the animations.
