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. (150 words max)

The three techniques are additive subtractive and formative (CNC). Additive is the incremental formation by increasing layers of volumetric sihouette. In contrast, Subtractive invovles the removal of material from a volumetric mass. The processes are often electronically, chemically, or mechanically reductiove which can be axial, surface or volume contrained. Formative is about using stresses such as compression, tension, shear or combined stresses to achieve the deformation or reshaping of materials. It is abot to reproduce the parametric models with accuracy efficiency controlled in terms of both geometry and measurements. However, there is restriction about the formative fabrication of the axis movement.

Each surface is created with four lines genrated from 8 selcted points which are controlled by using debrep and list item of a 150*150 cube. By djusting the number slider, a varation of tension between two surfaces were expereinmented. The experienments mainly explore the idea of surfaces with center attracted and edges repelled to form the graduation between big opening and narrow threshold in consideration of the spatial experienment.

SURFACE AND WAFFLE STRUCTURE Surface Creation

In the surface creatoin process, the tension between parametric fabrication and design of manual control was explored. Controlling two different parameters: patterns and location by using different method on two surfaces, a similar effect was tried to be achieved stimutaneously around the concept of light gap. On the surface 1, the patterns are mainly genrated parametricly in a wavy behaviour which the wave amplitute and direction can be controlled in the script (pg5). Adding a few exsited drawn patterns with control of height and moving direction in grashopper to balance . On the surface 2, parametric fabrication was used to controll the location of atterns which were drawn in a similar tension but with ifferent sizes of light gap and 3D shadow extrusion. However, the random split commans was choosed for this allocation, because the patterns themselves already have a strong link between each other. By controlling the ratio of split numbers and level of randomness, the script can create something unexpected.

*Developable surface was considered as pattern on srf1 are quad panels, the point was select grashooper and deconstruct the quad panel into 2

Overall, the idea of two surfaces was to create light gaps with a sense of randomness using ordered manipulation or in a opposite

Isometric View

Two surfaces both have a graduation and itteruption of patterns at the same time which formed a strong visual effect of constrast between regularity and irregularity. Surface1 acchieve the result by itterupt with irregular shapes and the surface 2 was applied with irregular allocation of shapes. They both successfully delivered the idea of light gap through different direction and size of opening through 2D and 3D patterns

Waffle structure was made as four by four in order to align with the grid of panelling which allow the light can come through directly. The shape of waffle visually suggest the circulation the pavillion. When people come through the wide opening, the overhang will be narrow. when they come throught the narrow walk path, over hang become wide which in two way forming strong contrast.

When nesting the patterns, putting them in roll are convient for later assemble process, number labelling for waffle structures help as well. In terms of model making, the tolerence must be considered as some of the light gap might be to big and too close to the edge which will be bend. Testing laser cutting allowed me to check the buildability of real model and made any adjustment as it needs.

The iteration 4 was selected for final pavillion design because there is more variation of space formed by substraction of Dypyramid and Prism in different scale and grouping method. The complexity of negative space is emphasised by the sloping edge and fragamented grid on top and bottom. The geometry of prism forms interesting void inside which creates many possibilies as a pavillion, in terms of the way of cutting, the void can be used as sitting area, sloping plane for walk, or the framing view opening. The solid part is characterised with itâ&#x20AC;&#x2122;s different size of plane, as at every angle, plane makes the strongest view of the pavillion. However, at different angle, the plane size and different intersections increasing the complexity and different possibiloities spatial experience of the pavillion.

I found the shape interesting as it has many possible sitting area and those area can be sloped walking plane at the same time. When walking up on the slope, the big hollowed circle can frame the view of outside. The geometry also emphaises the origianl idea of ifferent plane facade in different scales.
