GROWTH SIMULATION AND ANIMATION CREATION OF CORN BASED ON SKELETON MODEL

摘要：

To achieve the quantified and visualized expression of crop growth, we take corn as an example, proposed a simulation framework, which integrated parametric keyframe animation to the skeleton model. At first, to animate corn, we adopt a skeleton model for its topological structure, which is defined based on a precise geometric model. The dynamic creation of the parabolic curve of blade midrib integrated time variant is used to stimulate the elongation of leaf skeleton. With parametric keyframe technique, of which each keyframe parameters being acquired from the observed data or the output of corn growth model, animation could be obtained by manual interaction. Experimental results show that the proposed method could simulate the basic movements of corn growth visually with highly realistic rendering effects. This provides a simple and general dynamic process simulation for plant growth.
