Abstract: Crop growth process 3D visualization is one of the key technologies of virtual crop research, since morphological structure of wheat is complex and wheat growth visualization is not easy to realize. This study took wheat as the subject, on the basis of existing research results, combined with wheat growth simulation model and the morphological structure model, started with the system structure and function, system design and implementation, realistic graphics rendering technique (color rendering, texture mapping and light processing) and other aspects, built the wheat growth simulation and 3D visualization system, realized the combination of wheat growth model and morphological structure model, and finally realized 3D visualization of wheat growth process. Wheat growth simulation and 3D visualization system would provide visualization tools for wheat growth dynamic prediction, cultivation management control, crop plant type design, etc. and provide technical support for wheat ideal plant type selection, design of high yield, high efficiency, lodging resistance and optimization, etc..

Key words: wheat, 3D visualization, growth simulation, morphological structure
