参数化技术因其在建模上卓越的可调性和对复杂形体建筑良好的适应性,日益成为建筑设计的重要工具。以Rhinoceros平台的Grasshopper软件为例,对可视化节点式参数化建模方式进行简要介绍,结合正放四角锥网架范例和某体育场工程罩棚结构建模过程,给出参数化建模在空间网格结构建模中的基本应用思路。实例表明,参数化建模可大大提高工作效率,所建模型可快速修改调整,且可视化节点式参数化建模方式技术门槛不高,可推广使用。同时,也应看到参数化建模在处理复杂形体结构局部部位上存在一定局限性,需辅以少量人工干预。
Parametric technology is increasingly becoming an important tool for architectural design because of its excellent adjustability in modeling and its good adaptability to complex body building. Taking Rhinoceros platform’s Grasshopper software as an example, a brief introduction of visualization node-based parametric modeling method is presented. Combined with the example of quadratic pyramid grid and the construction process of a shed structure, the parametric modeling is given in the space grid The basic idea of application in structure modeling. The examples show that parametric modeling can greatly improve work efficiency, the model can be quickly modified and adjusted, and the visualized node-based parametric modeling approach has a low technical threshold and can be popularized. At the same time, we should also see that parametric modeling has some limitations in dealing with the local parts of complex body structures, and requires a small amount of manual intervention.
