细分/ Michael Hansmeyer

看到Michael Hansmeyer的作品时,我们会被其复杂程度和看似的精妙所震撼。Hansmeyer曾接受过建筑和计算机编程方面的教育,作为一名建筑师和程序员,他想要利用数学计算方法创造出一种全新的建筑表现方式。“一方面,计算机可以处理大规模和复杂的计算过程,这种规模和复杂程度运用手工方法很难做到。另一方面,计算机计算可以使一个计划产生无数排列方式。无论是输入还是计算过程的一点点偏差都会导致结果立即发生变化。与评价功能相结合时,计算机计算还可以在功能和美观层面循环优化计算结果,”Hansmeyer解释道。他的细分项目的特点是表面的几何形式错综复杂,创造出艺术表达清晰的各种不同柱子。2.7米高的柱子通过1米厚的薄板被预制成多层模型。

单独切割的薄板堆叠在一起,通过几个杆件连接在一起,这些杆件通过一个共同的核心穿透薄板。切割薄板时,3D模型数量惊人的600万个面都相交于一个代表薄板的平面上。正如Hansmeyer在他的网站上解释的那样:“这一步是生成一系列单独的线段,线段经过自交叉测试,随后结合在一起形成多边形。下一步是进行‘多边形中的多边形’的测试,删除内部的多边形。然后进行一系列过滤,保证凸状多边形能保持最小的狭缝宽度。最后一步要计算内部的位移,目的是要掏空薄片,减轻重量。柱子的平均直径为50厘米,由于有锯齿形状而且弯曲的地方时常有反转,因此切割部位的测量周长可达8米。”

到目前为止,最初的原型都是使用1毫米的灰色木板建造的,采用测试用ABS(丙烯腈—丁二烯—苯乙烯共聚物)、木材、金属预制的方法也正在逐步发展中。

“利用计算机设计建筑可以产生原来无法看到的形式。传统方法达不到的形式现在也可以实现。新的领域已经开启,”设计师补充道。


When we came across the work of Michael Hansmeyer, we were struck by the complexity and the seemingly delicacy of his work. Educated as an architect and computer programmer, Hansmeyer intends to create a new kind of architectural expression using the mathematics of algorithms. “On the one hand, their [algorithms] computational power can address processes with a scale and complexity that precludes a manual approach. On the other hand, algorithms can generate endless permutations of a scheme. A slight tweaking of either the input or the process leads to an instant adaptation of output. When combined with an evaluative function, they can be used to recursively optimize output on both a functional and aesthetic level,” explained Hansmeyer. His Subdivision project features geometrically intricate surfaces that create an artistically articulated variety of columns. The 2.7 meter high columns are fabricated as a layered model with sheets 1mm thick.

More about the process after the break.

The individually cut sheets are stacked and held together by poles that run through a common core. To cut the sheets, the astonishing 6 million faces of the 3D model are intersected with a plane representing the sheet. As Hansmeyer explains on his website, This step generates a series of individual line segments that are tested for self-intersection and subsequently combined to form polygons. Next, a polygon-in-polygon test deletes interior polygons. A series of filters then ensures that convex polygons with peninsulas maintain a minimum isthmus width. In a final step, an interior offset is calculated with the aim of hollowing out the slice to reduce weight. While the mean diameter of the column is 50cm, the circumference as measured by the cutting path can reach up to 8 meters due to jaggedness and frequent reversals of curvature.

So far, the initial prototype has been constructed from 1mm grey board and progress is being made on testing ABS, wood, and metal for the fabrication.

“A computational approach to architecture enables the generation of the previously unseen. Forms that can longer be conceived of through traditional methods become possible. New realms open up,” added the designer.
