Lindenmayer Systems are a mathematical formalism which was proposed by Aristid Lindenmayer in 1968 as a foundation for an axiomatic theory of development. This book presents the application of Lindenmayer Systems and Fractal Geometry to graphics-based plant modelling, a fascinating approach to visualizing growth functions in plants. For life scientists, mathematicians and computer scientists alike, this book will provide a unique and stimulating view at an interdisciplinary field of science.
