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.
