Abstract
A system and method for authoring and testing three-dimensional (3-D) content based on broadcast triggers using a standard VRML authoring tool. In one embodiment, 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 is provided. In this embodiment, the method comprises the step of defining a timelist comprising video triggers, wherein each of the video triggers represents a time at which an event is to occur within a 3-D graphics scene generated using the 3-D graphics platform, and wherein the timelist is stored in a data file that is an input format supported by the 3-D graphics platform. The method also comprises the step of periodically generating a simulation tick representing a simulated video frame from a simulated media stream. The method further comprises the step of generating time data for the simulation tick, wherein the time data is associated with the simulated video frame. The method also comprises the step of comparing the video triggers and the time data. The method further comprises the step of effectuating a behavior change for an object in the…
