This article focuses on the simulation modeling research of plants and plant ecosystems. The research is aimed at viewing and analyzing plant architecture and developmental process. The process involved in this research can be divided in two broad categories, image synthesis and scientific visualization. It is believed that simulation-based plant modeling makes it possible to capture the mechanisms of plant development in a biologically sound and visually realistic manner. The interdisciplinary character of plant modeling research is reflected in the diversity of existing and prospective applications of the models. Results of this research based on these models, looking 3D simulations of plant biology, ecology, and the physiological processes governing plant growth, including the effects of light, were found accurate and realistic. Some models seek to increase our knowledge of plant development and apply this knowledge to plant management in horticulture, agriculture, and forestry.
