A description is given of SimRoot , a geometric simulation model of plant root systems. As implemented on Silicon Graphics workstations, the data structure and visualization code provide for continuous viewing of the simulated root system during growth. SimRoot differs from existing models in the explicit treatment of spatial heterogeneity of physiological processes in the root system, and by inclusion of a kinematic treatment of root axes. Examples are provided of the usefulness of the model in estimating the fractal geometry of simulated root systems in 1-, 2- and 3-dimensional space.
