AI summary

A method of executing a physics simulation is performed in a system comprising a computational platform, a main application stored in the computational platform, a secondary application stored in the computational platform, and a cloth application programming interface (API) implemented in the computational platform. The method defines a cloth simulation call in the cloth API, and by operation of the main application, invokes a software routine using the cloth simulation call. Additionally, by operation of the secondary application, a state of the physics simulation is updated in response to the software routine.
