This paper aims to establish the leaf morphological visualization model based on the rice's growth external environment. Firstly, the support vector machine is adopted to establish the prediction models of leaf's physical attributes; secondly, the piecewise cubic Hermite spline curves are applied to visualize this model. This study, based on the quadratic equation simulation on the main leaf vein, presents that the leaf stretching direction can be realized with the integration method. The rice visualization model interacted with the environment can help people visually observe the growth morphological variation of the leaves and provide improvement ways for rice cultivation.
