| Today,with the development of technology,virtual technology has become a hot technology.One of the most important areas of research is the virtual plant.It attracted widespread attention and study of scientific research personnel at home and abroad.Generally refers to virtual plant by plant morphology analysis and research,its simulation,build the model plant growth and development,which can simulate control the growth state of a plant,to strengthen management,improve productivity and quality on a computer,the traditional farming,agriculture management and research methods are converted to modern information agriculture concept.As China’s main rice crop,related to the national economic lifeline of agriculture,Rice Growth shape model constructed by computer technology,three-dimensional visualization methods for rice yield,quality and innovation to provide innovative ways of thinking.Rice leaf morphology model,is based simulation of rice growth,and therefore,the study has important significance.In this paper,the main stem of rice leaves as the research object,the use of the Yangtze River to promote the cultivation of rice production in the two rice as test material.Through continuous observation of the indicators of rice leaf morphology,explore the variation between the measured data,model building leaf morphology and physiological parameters.Study content: through periodic measurement of physiological parameters in rice leaves,including leaf length,leaf width,leaf angle,etc.,the measured data were analyzed to establish a trend model blade length,leaf length and leaf position and leaf length and the relational model leaf width relational model,and the model checking.According to Rice Leaves flat morphology and spatial morphology using Bezier curves and a quadratic equation mathematical models were constructed two-dimensional curved blade edge profile and three-dimensional vein curves.Finally OpenGL and VC ++ programming visual modeling and leaves space three-dimensional model.Research programs of this article better reflects the characteristics of rice leaf edge,three-dimensional visualization of the blade is only associated with the blade length,width and other information.Thus,the blade virtual three-dimensional visualization of other plants provides a good versatility. |
