地形建模一二事

地图建模的几个小心得。

地图建模 1.0

适用于大部分位于城市之中的项目,去提取大范围的城市模型。以前往往会在城市设计竞赛中出现这种表达形式,还是比较有表现力以及学术感。 3月份在一个投标项目中,尝试去实现这种表达形式。

在我的认知中,一般实现的方式一种是通过cad导入su来进行手工建模,另一种是利用OpenStreetMap 的数据 导入rhino,利用参数化来实现模型体量生成。但都有各自的弊端,前者过于繁琐,后者难度较大而且与su的协同有一定的问题。

阴差阳错的发现了cadmapper.com这个网站可以直接生成su体量

(免费版只能通过1km*1km来拼接)

 


(流程图 workflow)


(好吧,还是有点复杂)

 

地图建模 2.0

一种更极端的情况是,甲方不提供cad,于是….

这个的逻辑主要是通过一些方法提取场地周围地图的高程数据

利用高程生成等高线,再通过rhino将等高线生成实体模型

(也可以进而contour出台地分层)
