Abstract: 【 Objective 】The 3D visualization function of virtual wheat growth holds significant importance for the quantitative research of wheat growth patterns.【 Methods 】In order to present the morphological and color changes of virtual wheat during growth, as well as its perception of lighting conditions, PyOpenGL was utilized to construct a 3D visualization system of simulated wheat growth. The system integrated morphological data with model construction, texture mapping, and lighting and shading techniques to simulate dynamic wheat growth and its field environment. The interactive and information display functions of the visual simulation system were designed by using Pyside6 user interface development tool.【 Results 】The study was based on the morphological characteristics of real wheat and the measured data,design the construction of the visualization system,can dynamically show the changes of wheat growth,real-time display of current wheat information description and simulation of the surrounding environment.【 Conclusion 】The system can intuitively and coherently present the growth process of wheat,it has a high degree of parameterization and extensibility,the corresponding growth effect can be quickly generated by modifying the basic data and parameters.
