ELI5: Explain Like I'm 5

Advanced Simulation Library

An advanced simulation library is like a toolbox for computers. It has a lot of special pieces inside that help make it easier for people to create realistic 3D worlds, create animations or make games. With this library, computers can create visuals that look much more believable than the basic visuals that the computer can make on its own. This helps make games, movies and other 3D visuals much more exciting and lifelike.
