Week Three

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

Kolerevic described three fundamental type 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 types of digital fabrication techniques that Kolarevic describes are subtractive methods, additive methods and two-dimensional fabrication methods. Computer Numeric Controlled fabrication with parametric modelling allows us to minimise the process of moving from digital to fabrication, as well as, improving the accuracy of the fabrication. CNC fabrication is controlled with the use of a computer system that works by referring to set of codes. This means, that the fabrication process can be modified by simply changing this code. Additionally, this allows for the whole entire process to be reverse engineered. Furthermore, the whole process can be modified systematically. CNC production has also been used in the building industry which would ease the fabrication of curved structures such as Bernard Franken’s “bubble” BMW pavilion. This technology has the potential to be used widely throughout industry design in the future.

Week Three

Surface Creation

Four points are taken from the cube to create two different curves that are used to make surfaces.

3

When generating surface interations in grasshopper, it is very easy to get surfaces that cross or intersect each other. However, crossing surfaces are not appropriate to connect to the waffle structure. So the selected surfaces for the final isometric are interwined without touching each other.


Week Four Panels & Waffle

This is the isometric view of the Panelling of my two surfaces. Openings on the surfaces of both panels are created to allow directional and artificial light go through. Different forms of the panels increase interest for the design. The modules can be scaled up or down according to diverse purposes.

The waffle structure are twisted to create a organic form. The forms of the panels change responding to the waffle structure.

Week Four

Laser Cutting

After applying meshtonurb command in Rhino, I unrolled the polygons. In order to get the tabs for the unrolled surfaces easily, I add tabs in Grasshopper. Then all the width of the tabs can be changed at one time according to needs.

In the template for laser cutting, text tags are located next to the corresponding surfacs to keep track of the waffle.

Week Five

The creation of the boolean form begins with setting one cube with the grasshopper script. Acctractor points and acctractor curves are used to genertae variation of iterations. Platonic lcosahedron, platoinc tetrahedron, sphere and platonic dodecahedron are plugged in the grasshopper script and baked to geometries. Then I used boolean difference command in Rhino to get the intersecting geometries.

Week Five

Isometric

The dodecahedrons booleaned within the cube are of different sizes so that interesting intersecting spaces are generated with various steps and sections. The gap space between two booleaned geometry creates a cantilever extending out, showing the boundaries of the booleaned objects and the original cube. Intersections that do not interact with the surface envelope create heavier darker spaces, giving out a sense of closure and privacy. Where the intersecting geometry interacts with the surface envelope creates a positive open space, which can show a contrast between the light open space and the more closed sunken space.

Week Six

Final Isometric Views The scales of the module should be changed to create different functions and fit people’s diverse purposes. The openings to the top allows direct skylight into the space. People can sit on the bench near the windows to enjoy the sunshine and fresh air.

In each module of the panels, the peaks of both of the pyramids are cut away, which provides opportunities to the people standing outside the structure to have a look into the inside. Artificial light can enter the volume while a sense of closure and privacy is created.

The panels can be placed on a vertical wall so that people inside can look outside through the protruding perforations. And people walking outside can gain a look into the inside. So this works as a place for information exchange.

Perforations are o two faces of each paramids and some of the open ings in the panels are orientated up to let directional skylight enter the volume. During different times in the day, sunlight can also projects into the volume through side openings. So this allows for the light source to become more present in the space during the day for mutipl purposes.

Two sides of the hollow waffle structure twist at different angles, creating a big opening towards the top. The twisted facades of the waffle structure direct the views of the openings thus limit the amount of light that enter the space. So the light and shadow in the interior space can be designed for specific functional use.

Panels are smaller at the bottom and the sizes increase gragually towards the top of the volume. Additionally, the directions of the openings change according to the form of the waffle structure.

Where the intersecting geometry interacts with the surface envelope creates a positive open space, which can show a contrast between the light open space and the more closed sunken space.

This geometry is one eighth of the original cube with the booleaned Platonic dodecahedrons.

Intersections that do not interact with the surface envelope create heavier darker spaces, giving out a sense of closure and privacy.

The dodecahedrons booleaned within the cube are of different sizes so that interesting intersecting spaces are generated with various steps and sections.

When two geometries intersect with each other, an open transitional space is formed and this can be a threshold linking the interior and exterior spaces.

Appendix

Process

After I got the atrractor points, I baked them into Rhino and used the grasshopper script to set multiple points. In order to make them appear more obvious and clear, I chose to make the points into spheres with the Sphere command in Grasshopper.

Appendix Process

When the “Centroid” of Area shows as graft and the “Location” of Text Tag 3D shows as graft, the texts that are used for keeping track of the waffle structure are wrong. Then I changed the Graft of Location into Flatten so the texts appear right.
