According to the analysis of cotton morphological topology characteristics and spatial distribution law,a virtual plant visualization method was proposed using three spline interpolation curves to control the plant parameters. Based on this method,geometrical models of organs including bolls,leaf,branch,etc were generated to build cotton group under the organ position parameters with a tracing method step by step. The model could effectively reflect the distribution characteristics and spatial topological structure of cotton plant shape through comparative analysis. Finally,MATLAB was used as the developing tool to exploit a visualization system based on the cotton morphological parameters,then we conducted dynamic collision detection and parameter optimization,and achieved the output of cotton population vi
