Abstract:
A computer implemented method for authoring and testing three-dimensional (3-D) content based on broadcast triggers using a standard authoring tool of a 3-D graphics platform, said method comprising the steps of:a) defining a timelist comprising video triggers, each of said video triggers representing a time at which an event is to occur within a 3-D graphics scene generated using said 3-D graphics platform, said timelist being stored in a data file that is an input format supported by said 3-D graphics platform; b) periodically generating a simulation tick representing a simulated video frame from a simulated media stream; c) generating time data for said simulation tick, said time data being associated with said simulated video frame; d) comparing said video triggers and said time data; and e) responsive to a match between one of said video triggers and said time data, effectuating a behavior change for an object in said 3-D graphics scene such that said behavior change is synchronized with said simulated video frame in real-time.
