Critical Reading: Kolerevic B. 2003. Architecture in the Digital Age

Kolerevic described three fundamental types of fabrication techniques in the reading. Outline the three techniques and discuss the potential of Computer Numeric Controlled fabrication with parametric modelling.

According to Kolerevic, subtractive, additive and formative fabrication are the three basic techniques to produce three-dimensional objects.

Firstly, subtractive fabrication is a way to remove particular volumes from a solid. However, there are many limitations of subtractive fabrication as the process of milling is constrained by axes, surfaces and volumes.

Next, additive fabrication involves the accumulation of material layers to form a solid. The additive fabrication also has a limited application because of the limited size of object that can be produced, costly equipment and lengthy production time.

Lastly, formative fabrication deforms or reshapes the material forms by using mechanical forced, heat or steam. Different from the subtractive and additive fabrication, formative fabrication could be applied in a large scale work with more accuracy based on the numerically-controlled system.

Computer Numeric Controlled fabrication is a way to design and build the 3D model directly in the software. It can provide the precision of measurements and forms of the materials which are important for constructing buildings designed with parametric modelling.

The script of two surfaces starts with constructing a 150 × 150 × 150mm box and extracting edges by using command “DeBrep“. Four curves are selected by using command “List Item”. Each curve is separated into five even parts with points on by using command “Divide Curve”. Then the lines are constructed by connecting two points which can be adjusted. The surface is made by “Loft” command. The 5 × 5 grid on each surface is created by command “Surface Domain Number“. The height and direction of grid can be adjusted by commands “Offset Grid” and “Point Attraction”. This provides more variations in scale and trend of paneling units. The moved grid, original grid and the geometries become input for command “Morph 3D” which can produce paneled surfaces. As two geometries are chosen and applied on one surface, I use command “Sift Pattern” to create a true and false pattern for the arrangement of geometries.

This two surfaces have the same shape. I rotate them into different directions in order to create different spaces and light effect. Surface 1 has less connection to the ground, the threshold surrouded gives more public space. Surface 2 create more private space since it is more enclosed.

Since there is a large opening at the top, the interior area closed to surface 2 are more likely to cause shadow. There might be a long pause area.

In this iteration, I maintained surface 2 from Study 1. And change one surface into a more flat and rigid surface. One main reason is beacuse I failed to create the waffle. As the surface changed, the privacy ratte increased. This is beacuse surface 1 also helps enclose the interior space.

And the extorior area projected under surface 1 gives more shadow which could be a long pause area.

Surface 2

In Study 3, I build two surfaces with two similar shape but less curved compared with Study1. This two surfaces create a large entrance but still invovles a certain degree of privacy in terms of the interior space. This shapes povides less threshold in the exterior space. The angle ceated at the entrance provides a circulated entrance rather than direct entry.

This is my final work. This two surfaces differ in scale and shape. Surface 1 is smaller than surface 2. Both of them is inclined into same directions which give me different threshold. The extrior area behind surface 1 has the similar quality with the study 2’s surface1. The interior space close to surface 2 has the similar quality with the study1’ surface 2. The way that the sun light enter the pavilion is also effected by the shapes of the surfaces.

This panels create the exterior space with a certain degree of privacy as the panels helps to enclosed the space around people. It also provides a lean on surface which people might pause.

The waffle structure creates a large entrance and large interior space.

The inclined angle of surfaces provides different threshold.

Inclined angle provides different threshold.

Waffle forms big entrance.

Panels provides rest area.

Visual Scripting of Parametric Model

The script of Task B also starts with building a 150 × 150 × 150mm box and deconstructing them by command “DeBrep”. Then the grid is created by command “Surface Domain Number”. I insert “Point Attraction” o manipulate the internal structure to create different types of space. Then I use “Cellulate 3D Grid” to creat mesh. The centroids can be found by command “Volume”. This helps me to locate the boolean objects. I basically build up cylinders and deconstruct them into separated surfaces. I use command “scale” to adjuest the upper and lower circle. Then “loft” them in Rhino to build my own geometries.

SOLID AND VOID Volume Creation

Spheres helps to create a coherent space that has more connections between space.

Doughnut shapes strengthen the connection between spaces.

This volumes has been manipulated with different height, scale and the rate of the enclosing. As height increases, the privacy rates increase. The more the space is enclosed, the privcay rates rise as well.
