Abstract:
Systems and processes are described below relating to evaluating a dependency graph having one or more temporally dependent variables. The temporally dependent variables may include variables that may be used to evaluate the dependency graph at a frame other than that at which the temporally dependent variable was evaluated. One example process may include tracking the temporal dirty state for each temporally dependent variable using a temporal dependency list. This list may be used to determine which frames, if any, should be reevaluated when a request to evaluate a dependency graph for a particular frame is received. This advantageously reduces the amount of time and computing resources needed to reevaluate a dependency graph.
