PROBLEM TO BE SOLVED: To provide methods and systems for constructing surrogate models for use in interactive experiences.SOLUTION: One embodiment begins by defining a model that includes a parametric state model and a design variable vector and represents a real world system. Next, first and second experiments are performed to determine a response over time of the parametric state vector and to produce a dataset of the parametric state vector and the design variable vector as a function of time. The dataset is then modified with one or more derivatives of the parametric state vector and a set of surrogate differential equations is constructed that approximates a higher derivative of the parametric state vector relative to that in the dataset, and the set of surrogate differential equations is stored as a surrogate model. The surrogate model is then provided from memory in a manner of accelerating simulated behavior in response to user interaction with the model.SELECTED DRAWING: Figure 1
