Visual Models of Plants Interacting with Their Environment ´ ˇ 1 Radomır Mech and Przemyslaw Prusinkiewicz University of Calgary ABSTRACT mayer proposed the formalism of L-systems as a general framework for plant modeling [38, 39], and Honda introduced the first computer Interaction with the environment is a key factor affecting the devel- model of tree structures [32]. From these origins, plant modeling opment of plants and plant ecosystems. In this paper we introduce a emerged as a vibrant area of interdisciplinary research, attracting the modeling framework that makes it possible to simulate and visualize efforts of biologists, applied plant scientists, mathematicians, and a wide range of interactions at the level of plant architecture.
