摘要: Rice is the most important food crop in China and the world. Displaying the growth, development and yield formation of rice ( dynamically Oryza Sativa L.) is beneficial to culture management and crop science research. The primary objective of this study was to develop a growth simulation model-based visualization system to reflect the time-course dynamics of growth, development and yield formation. The fundamental algorithms of rice growth, development and yield formation, which is various with the variety, environmental factors and production levels, were formulated from the existing literature and research data. Based on the daily output of the rice growth simulation model, and combined with morphological formation and growth rules of rice root, stem, leaf, ear, and so on, the mathematic model for changes of morphology in rice was set up. Using computer graphics, VC + + and OpenGL, a 3-dimensional visualization of growth, development, and yield formation will be realized based on crop growth simulation model data and a 3D animation technique. The 3D system can basically reflect the rules of real rice growth, development and yield formation, which will have some characteristics such as simple structure, mutual interface and realistic images.
