Efficient simulation of vegetation using light and nutrition competition

We introduce a new method for the visualization and simulation of the growth and developments of competing plants. In this method the plant competition for resources is illustrated as aboveand below-ground competition. The strength of the below-ground competition depends on the neighboring root biomass. The strength of the aboveground competition depends on the neighboring plant body biomass. We provide a simple and efficient simulation method for this competition that involves symmetric and asymmetric competition. It is shown that each plant influences its neighbors in at least nine different modes of competitions. The method allows us to produce biologically plausible plant populations.
