Throughout the history of game development, the physics behind the real-time hair simulation has continued to pose a challenge due to lack of availability of computational resources required by the system. Unlike rendering an animation, where the requirement of real-time simulation is absent, game hair physics needs more efficiency when it comes to utilization of computational resources.

Accurate computer simulations of any real-life physical phenomenon do not exist. Numerous ­variables need to be considered for ­producing precise simulations to ­mimic the interactions in real-life.
