1. A method for performing physics simulations on at least one graphics processor unit (GPU), comprising: mapping physical parameters associated with at least one mesh into a plurality of memory arrays to set up a linear system of equations that governs motion of the at least one mesh depicted in a scene; and performing computations on data in the plurality of memory arrays using at least one pixel processor to solve the linear system of equations for an instant of time, wherein modified data representing the solution to the linear system of equations for the instant of time are stored in the plurality of memory arrays.
