农作物生长模拟三维场景整合平台设计

提出了基于组件和插件的农作物生长三维场景整合平台。该平台提供了一系列3D几何与计算组件，包括曲面、高度场、地形等3D对象，场景组织、绘制引擎、碰撞检测、动画生成等计算组件，以及光照、摄像机的虚拟对象；基于统一定义的插件接口，能够将由不同研究团队开发的植物生长可视化模拟模型嵌入到平台中，从而为农林植物生长模拟模型的整合、重用和互操作提供一个灵活的工具。平台提供了图形化的交互式设计界面，用户能够快速地构建一个复杂的三维农业生产场景，并进行交互式的农作物生长模拟。实验结果表明，平台的交互设计和三维场景绘制能够达到实时的速度，在600万多边形规模的场景中，场景绘制的刷新率达到18帧/s，能够满足实时交互的需要。

Design of Framework for Integrating 3D Scene of Crops Production

A flexible component and plugins based hybrid framework for integrating 3D scene of crops growth and its process was presented. This framework was designed to facilitate the integration, reusability and interoperability of heterogeneous models and techniques. The proposed framework was consistd of a complete set of 3D geometric components for modeling and visualization, including surfaces, height fields, terrain and lights, and a group of computing components, such as scene organization, rendering engine, collision detection, animation generation and so on. Based on the united defined plug in interfaces, models for visual simulation of plant growth which developed by different research teams could be embedded into this framework. Users could create rapidly a prototype of 3D agricultural production scene and simulate the growth of crops, by using a graphical designing environment. The experimental results demonstrated that the interactive design and 3D scene rendering could be done in real time. The rendering speed would reach to 18 fps in 3D scene with up to 6000000 polygons.
