基于Sketch Up软件的园林植物建模技术研究

Research on the Modeling Techniques for Garden Plants Based on Sketch Up Software

应用新生的计算机辅助园林设计工具——Sketch Up软件,对园林植物建模的3种技术进行对比分析。结果表明:1)使用Sketch Up软件进行园林植物建模的3种方法完全可以模拟自然界中植物形态结构,并且使用剪影法、"十字树"法获取植物形态信息的方法比较简单。2)建造较大的园林场景可以使用剪影法和"十字树"法进行植物建模。3)在处理较小的园林场景时,模型量较小,全部应用三维模型是可行的。在处理较大的场景时,近景用三维模型,远景用贴图法的处理方法较好。

Three modeling methods for garden plants are compared and analyzed with Sketch Up software.The results show that the three techniques all can simulate the plants＇ morphological structures in the natural world,and sketch method and ＂cross tree＂ method are relatively simple.For large garden scenes,sketch method and ＂cross tree＂ method can be applied for plant modeling.For small garden scenes,three dimension modeling is recommended.For large scenes,three dimension modeling is suggested for close shot,while mapping method is good for distant view.
