2.5 工作流程——一个概念设计
Created on Wed Sep 21 17:40:01 2022; Last updated on 2024-09-10T09:54:43+08:00 @author: Richie Bao
用代码写设计的根本还是设计自身,只是因为使用的工具不再限于传统意义上的三维推敲,设计思维有所变化,这包括:
- 由对空间几何三维推敲的直接操作,转换为如何建立代码逻辑实现空间几何形态的变化(这包括 GH 组件的可视化编程和 Python 的文本式编程);
- 思考空间几何形态变化的逻辑,并以代码实现产生设计,而不再是三维推敲方式确定设计后再转换为代码逻辑的方法;
- 将算法融入到设计当中,用于设计分析并适应生成设计,或直接用于变化设计形态。
图 2.5-1概念设计构建的主要逻辑为:
- 构建空间 voronoi 单元,为空间划分的方式;
- 根据功能建立空间点位置,分配不同功能组空间数量(可转换为空间体量、建筑面积等指标)。随机提取各个功能空间组,从多个随机结果中挑选适合的空间结构形态;
- 通过 Dijkstra 算法,给定空间单元位置,建立两点间的最短路径,实现连通;
- 随机移除指定数量的 voronoi 单元,变化框架结构;
- 用 SubD 将框架形态变化为骨骼态。
对应设计逻辑,考虑组件使用的通用性和弹性如图 2.5-2 ,由 Python Script 构建组件,1_voronoi_basic design structure(BDS)对应“构建空间 voronoi 单元”;1_objs group对应“功能空间组”;1_Shortest Path_py对应“两点间的最短路径”;两点间的最短路径对应“框架骨骼态”;及用于统计建筑指标示例的1_stats_vols;和标注示例的1_textdot。

图 2.5-2 一个概念设计的程序
2.5.1 概念设计结构
ghpythonlib库,即nic可调用 GH 基础组件和扩展组件。因为 GH 为参数化设计,因此 GH 的一些组件功能并不会在RhinoCommon和RhinoScriptSyntax中。在使用ghpythonlib.components(ghc)时,可以直接参考 GH 组件,通常 GH 组件的名称就是ghc包含的方法;输入和输出端就是该方法的输入参数和返回值。如果返回值有多个值时,为字典模式,键通常为组件输出端的名称小写,或者直接参考 Python Script 交互解释器中给出的帮助提示。
构建空间 voronoi 单元直接调用了 GH 组件的Box2Pt()建立盒体,Populate3D()由盒体生成随机点,Voronoi3D()生成空间 voronoi 单元,BrepEdges()获取单元边线,Volume()提取单元中心点,DelaunayEdges()构建 Delaunay 网络。用ghc调用 GH 组件书写 Python 代码,与直接用 GH 可视化编程途径如出一辙,但是可以将多个组件组织在一个 Python Script 组件中,并借助 Python 语言的一些方法,例如lambda,map()等函数提取和组织数据;条件语句建立以不同点构建的 delaunay 网络等。因为无限扩展的 Python 工具,大幅度提升了 GH 辅助设计的能力,增强处理设计相关问题的可能性,使得解决问题的手段也更自由。

进行分组时,为给出拾取点Gpt,由ClosestPoints()方法提取给定数量Gnum的最近点,并由最近点的索引(cp_index键)提取 voronoi 空间单元。

2.5.4 结构形态
位于GH->Surface->SubD下的MultiPipe组件,在 Python Script 下调用时位于Kangaroo之下,为ghc.Kangaroo2Component.MultiPipe()。
定义结构形态的 Python Script 组件包括随机移除给定数目的空间单元和调用MultiPipe()两部分。这两部分都比较简单,可以由 GH 组件可视化编程直接实现,这里将其集合到 Python Script 中的一个目的是,仅引出MultiPipe组件输入参数的NodeSize和StrutSize,其它参数默认或固定,简化输入端。
各类 Python 库,或者 GH 在版本升级更新后,调用的方法位置有可能发生变化。可以通过网络搜索,或者查看官方提供的文档定位新的位置。

设计内容的各类指标统计是设计过程中辅助调整设计和最后统计报表的必要组成部分。统计输出方式,一是,直接从组件的输出端输出为 GH 的数据结构类型,如本例;二是,定义类,以类属性的方式存储数据,以类的实例化对象输出。实例化对象并不能为 GH 组件所使用,需要根据具体目的,再在 Python Script 中书写代码,完成数据的提取和 GH 数据类型的输出。
