This paper introduces a combined discrete/continuous model of plant development that integrates L-system-style productions and differential equations. The model is suitable for animating simulated developmental processes in a manner resembling time-lapse photography. The proposed technique is illustrated using several developmental models, including the flowering plants Campanula rapunculoides, Lychnis coronaria, and Hieracium umbellatum.Keywords: animation through simulation, realistic image synthesis, modeling of plants, combined discrete/continuous simulation, L-system, piecewise-continuous differential equation.
