- 摘要:
- 基于郁金香不同品种、不同播期的2个生长季试验材料，采用L-System建模方法，构建了郁金香3D可视化模拟模型，以期为郁金香的形态结构分析提供科学参考。结果表明：通过构建郁金香生长发育的L-System，利用郁金香器官的拓扑结构确定了各个器官的位置关系和连接方式，利用NURBS曲线建立郁金香茎的仿真模型，并利用三次Bezier曲面的原理，构建了郁金香的单叶片和单花被曲面模型，得到了郁金香3D可视化模拟效果图。
- Abstract:
- Based on the tulip experiment data in two growing seasons with different varieties and sowing dates,the 3D visualization simulation model for the tulip adopted L-System modeling method was built to provide scientific references with morphology analysis.The results showed that,by building the L-System of tulips growth,the topology structure of tulip organs were built to determine the position relationship and connection mode.The tulip stem simulation model was built based on NURBS curve,and the single blade and floral envelope surface model was built by using the principle of three times the Bezier surface.Finally,the tulip 3D visualization rendering was simulated.
