A method is needed for producing numerical descriptions of three-dimensional geometries of tree stands that will approximate descriptions resulting from actual tree-stand measurements. This report presents a concept for mathematically simulating the physiognomy of a single tree, in anticipation of further work toward computer simulation of any specified type of structure, from an individual tree of a given species to a forest composed of some given mix of species. The concept described herein is a generalized step-by-step procedure involving dimensions, locations, growth quanta, and direction of stems, branches, and twigs. The result is a line network representing a single tree.
