提出了一种基于粒子系统的虚拟作物器官的建模方法,通过这种方法结合作物生长中 取得的实测数据能较好地模拟作物器官在三维空间中的形态及其动态生长过程。利用计算机图形学技术,通过VC++.net 和OpenGL 实现了作物器官的动态生长。 关键词:粒子系统; 虚拟作物;动态生长;OpenGL Abstract: An approach is proposed to model the virtual crop organ based on paticle system in this paper.and simulates the appearance of organs in three-dimensional space and their dynamic growing process.By means of techniques of Computer Graphics, dynamic growing process of crop organ was realized on the VC++ .net and OpenGL graph engine.
