For task A, my concept is to balance lightness and darkness, as well as the amounts of 2D and 3D panels. So on my model, one surface has 50% openings and 50% enclosed panels. On the same surface, there is the exact same ratio of 2D and 3D panels.

On the other surface, it is various shape of pnaels but all 3D and enclosed. the whole structure acts as a tunnel where people can walk into for sheltering and enjoy a certain extent of privacy (created by the enclosed surface) and freshness (created by the openings).

For task B the concept of lightness and darkness still remains. In my task B model, there is a series of space defining by the spheres. They are inner-connected to each other but most of them sit within the structure without exposing to the outside.

In this way, there is more a sense of mistery and could trigger people’s curiorsity when they are circulate in this space.

I used point charge component instead of spheres in grasshopper to archieve this effect.

a large opening to let lights in and could therefore could change the local climate of these a few connected spheres.

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)

There are three fabrication techniques according to Kolerevic: Subtractive Fabrication, Additive Fabrication and CNC, which means computer numeric controlled fabrication. Subractive Frabrication is to void a geomery, and additive is to form a geometry while the robot arm move in a xy plane to add up layers, whilst CNC combines the designing process and fabrication process together, and the nature of it distincts it from the previouse two fabrication techniques.

SURFACE AND WAFFLE STRUCTURE Surface Creation

the left part of the script is for generating the surfaces, the middle part is for make2D in grasshopper (and therefore export for journal), the left part is for generating various offsetted grid for the further panelling process. I used fixed offset distance, as well as point attractor and curve attractor to find which is the best fit for the model.

And I used make2d in grasshopper instead of rhino because no matter how much i change the surface, i can just run the make 2D command once, instead of baking them again and make 2D in rhino. this process saves me time and is easier to adjust the lineweight in rhino.

SURFACE AND WAFFLE STRUCTURE Surface Creation

the final model for part A assignment is shown on the left. In this model, the two surfaces have different panelling. The first surface has a balanace combination of 2D and 3D panelling; although all grids have the same custom panel, overall half is 2D and half is 3D. It is also interesting that there is an opening on the 2D panels which adds more dynamics to the shape and appearance. The size of the opening can show what is inside the structure, without showing too much of the waffle structure.

On the other surface of the panel (not shown in this image), I adjusted the grids to 5*1 instead of 5*5, and made a strip of 5 custom variation panels. In doing so, i do not need to bake them and change them in rhino, but i can still have different panels on one surface, without changing the script.

SURFACE AND WAFFLE STRUCTURE Photography of Model

one major difficulty of task A is model making. When i glued the panels, the paper is very flexible and sometimes it got a bit distorted. and this distortion would therfore affect the whole shape of the panel surface, and made it very hard to attach to the waffle structure.

13

Visual Scripting of Parametric Model

This is the fundamental script of the boolean model, largely based on what has been taught in the workshop. With this script, we can generate the basic boolean model.

14

SOLID AND VOID Surface Creation

These are two models generated with the fundamental script, and they were baked into Rhino and operated with boolean intersection to extract those smaller sections. I like the left model because all spheres are attracted to one corner which provides interesting intersection. and the right one is rather uniform, with a moderate change in the radius. One of the section model of it (the first left one) is very attractive with the arch and transformed top.

15

16

SOLID AND VOID Isometric view

I choose this as my final model because of the dynamic nature of it. I used point charge instead of sphere to plug into the centroids to generate new geometries, in this case all the “spheres� generated in this process are interacted with each other through some theories resemble an electric field.

The spheres are touching the adjacent others, and the size of it is affected by the distance of next centroids.

So when people circulate in this space, they would be exploring a series of space defining by each spheres, and the joints would act as threshold.

Photography of Model

I have 3D printed 4 models, but some of them dont look good because of either wrong setting or very thin edge. Some edges are less than 2mm but since it is not the supporting part of the model it could still get a decent quality. but in one of my model i have two intricate arches, which have been broken in the printing process due to the weight of materials that they are supporting.

The one generated by point charge is very interesting. it has two main parts and they are roughly symmetric. the triangulated surface makes the shape very dynamic.

Task B Matrix i chose to develop my model with spheres because spheres are less rigid than boxes. I adjusted to point grids and centroids to make the spheres and the location of them more interacting.

21

Appendix

Process

this is when i was trying to use a completely different concept to do the boolean difference, in this model there is no centroids and the reconstructed boxes, only some cones generated in a similar manners. But It does not work because all the cones are connected to each other and they would generate a huge void in the box.

22

Appendix Process

the second experiment is more successful. I used point chare instead of spheres to plug in, and the outcome is surprising me with the triangulated surfaces.
