基于OpenGL的苹果枝条生长可视化研究

Design and Implementation of Apple Tree Form Training System Based on OpenGL

为解决果树整形试验中不可逆、难以快速成型的缺点,以小冠疏层形苹果树为研究对象,采用马尔科夫随机过程模型建立苹果树枝条的随机生长模型。在此基础上,利用Visual C++与OpenGL图形引擎实现了苹果树枝条生长过程及光照、阴影在降雨降雪等自然环境的三维可视化仿真。通过调控生长参数来模拟不同生长条件下的果树枝条发育过程,为苹果树树形培训和推广提供了一种可行的技术手段。

To solve the problem of irreversible and rapidly prototyping of faults in fruit tree shaping experiment, the small and sparse canopy shape apple tree was taking as the research object, through the analysis of growth regularity and branches of apple tree branching model, using stochastic growth model of apple tree branches to establish Markov process model. On this basis, three-dimensional visualization simulation achieves the apple tree growth process and light, shadow by Visual C＋＋ and OpenGL graphics engine in rain and snow and other natural environment. Through the regulation of growth parameters the branches of the fruit tree under different growth conditions was simulated, the development process of simulation provides a feasible way for the shaping training of the apple fruit tree.
