1. In a projection system, a method for generating a lightfield simulation, said method comprising:
driving a beam-steering spatial light modulator (SLM) with a first set of drive values to place said beam-steering SLM in a first state at a first time;
driving said beam-steering SLM with a second set of drive values that cause said beam-steering SLM to transition from said first state of said beam-steering SLM to a second state of said beam-steering SLM at a second time;
modeling said transition of said beam-steering SLM from said first state to said second state;
determining a third state of said beam-steering SLM at a third time based at least in part on said model of said transition of said beam-steering SLM, said third time occurring between said first time and said second time; and
generating a lightfield simulation of a lightfield generated by said beam-steering SLM at said third time based at least in part on said third state of said beam-steering SLM.
