PART BCRITERIA DESIGN

B.1RESEARCH FIELD

T a k i n g t h e i d e a o f parametr ic technology design to part B research, Patterning is one of the best way to express such design approach. Patterning bring complexity to both the structure and the appearance to a design. In addition, thinking of the connection between each element would become an important factor when doing patterning design.

-Warehouse in ShanghaiThis project is highlighted by its unique faade. With each rotating of the box, the faade appears as wave patterns, such pattern brings attraction and complexity to the architecture. On the other hand, considering the fabrication, the connections between the boxes should be well considered to avoid collapse of the building. Patterning used in this project brings fluidity and aesthetic to the architecture.

-Dior in Shinsaibashi, OsakaThis Dior building is the same with the one in Ginza. Unlike the previous project, the faade of this building is more simple with single surface. The faade is more focusing on the image referenced to the wall and the effects provided with other component such as light. Looking at the wall in detail, the patterns are expressed by circles with different radius. Also the lighting makes the faade look more complex.

B.2CASE STUDY 1.0

OMA- McCormick Tribune Campus Centre

This case study uses image sampler to provide uv value for points within a surface framing, then by creating a set of list and reference different shapes to the list, the shapes should be oriented by different integer coming out from the expression.

SPECIES 1

These iterations are changing of the slider for the integer.when the slider (b value) is 0, there are no various patterns showing on the grid, as the value increase to 0.5-2.5, there are patterns shown refering to the image sampler. When the b value invrease to >2.5, the pattern started to fail as there are components missing.

SPECIES 2

a*b a+b a-b a/b

Apart from the slider, the expression also change the value of the integer, therefore different expressions would lead to different patterns.Unlike the change to slider, the pattern shown become less similar to the sample image as the expression changes.

SPECIES 3The ratio of black and white area of the image would also result different patterns. From image 1 to 4, white part of the image is increasing and become more spred in the image, the resuld shown on the pattern becomes less consolidated than the two images before.

SPECIES 4In this type of iteration, the surface which referenced to be the frame is changing , and various patterns shows on the surface. A pyramid cannot be successfully referenced due to the sharp edges of the geometry. The geometry that referenced to the defination were continuous surfaces with no sharp edges.

SPECIES 5When change the curves which w i l l show on the patterns, t he pa t te rn wou l d no t be successfully formed. This may be caused by the radius of each single shape.Also changing the slider for the integer will cause missing of one group of curves, hence t he pa t te rn wou l d no t be successfully produced.

Dividing the oriented curves to points and add one spinforce to the surface, the field lines that go through these points will form ciecles or circular lines due to the position of the spin force.

For this iteration, point charge are referenced to each point which divided from the oriented curves. Then field lines go through points created by populate 2D.The result clearly shows the attraction from each point charge to the field line also there are less field lines created at the eaged of the shape.

Metaball expressed the patterns more clearly because the position of points are regularly spread.

Similar with metaball, voronoi would express more interesting patterns using irregular points than regular points.In this result, the overlapping of the straight lines could form a rather complex appearance of the shape.

When the spin force is not set in the same 2D plane with the points but above the points, field lines will no longer produce circular curves but rather explosion-shape.

4 SELECTED ITERATIONS

This iteration pushed the referenced surface to a 3-dimentional shape, and as a result the patterns are still able to appear.By testing the reference surface of this project, I found out several different types of geometry which could make the definition work, but there are also types of geometry ( which are almost 3D geometry) could make the definition fail.

I choose this iteration because this result is a 2D shape, however to look at the image produced, it looks like a 3D pattern. This result really shows the interesting parts of point charge and field lines.

Unlike spin force in the same plane, the spin force used in this iterartion results a unique shape of field line. Also this kind of shape may be produced by some definitions other than spin force.

This iteration also uses field lines and point charge but in a 3D condition, as a result, some interesting shapes are created. In the excercise of field lines, similar results were created using other component in Grasshopper. Therefore I found this iteration successfull because it help me discover different approach to a similar result.

SELECTION CRITERIAAfter testing the definition and push them to create new form, I find it important for a design to be aesthetic and the ability to be undercontrol. Some iteration I made were unique but did not have the quality for people to appreciate. Also some of the iterations are out of control and results in a pattern that hard for people to look at and understand. In addition the practicability is also important for design, some of the iterations are not suitable or proper to use as a design.Therefore I will choose Aesthetic, Control and Practicability as my selection criteria.

SPECULATESome of the pattern g e n e r a t e d f r o m t h e original geometry would be efficient on producing building facade and some of the iterations would be used to create grains onto a surface. The 4 selected iterations would all be suitable for creating unique grains on a surface, and the metaball iteration on the left would be better for a pattern facade.

B.3CASE STUDY 2.0

Dior, Shinsaibashi, Osaka, Japan

-Initial Thoughts

Base Geometry

Image Sampling

Reference Circles

-ResultThere are no patterns showing on the surface, the radius of the circles are almost the same, faliure for this thought.

-Change Image

After changing the image, there are still no patterns showing on the surface or the patterns are hardly to be seen.This would be cause by the thickness of the lines in the image

This image successfully referenced to the surface, but the range of the grid is too small, the result of this image sampling does not look similar to the original project

Using 2 image sampler to the definition would help appear the pattern more efficiently.As a result, the images are sucessfully referenced to the surface. Although there are overlapped circles on the surface.

-Creating Facade

The next step is to make a vertical facade appear such pattern.However the circles created on the facade keep in a horizontal way.

-UnrollBrep

As image sampl ing is not working, I thought of unroll b rep and reference the pattern back onto the original brep.

B.4TECHNIQUE:

DEVELOPMENT

Radius changing of the circles effectively changes the appearance and the intensity of the pattern.Aesthetic:2Control: 4Practicability: 4

W h e n t h e r a d i u s become too large , there are overlapping of the circles, which caused the intense look of the surface.This kind of overlaps wou ld have l ower p o s s i b i l i t y f o r practiceablity.

This set of iteration is changing the values inputed to the replacement set.Each value controls some of the circles, unlike the previous iteration, changing the value would cause sudden changes to some of the circles rather than all of the circles.Aesthetic: 3Control: 2Practicability:3

These iterations focused on changing thereferenced shapes to rectangle for further 3D solids.The 3D outcomes looks better than rectang les because it is hard to control the length and width of the rectangle and avoid overlapping.For the 3D iteration, the cy l inder appears h igh ly density of the pattern and create an attractive outcome.Aesthetic: 4Control: 3Practicability: 2

Lower value in practicability is because such 3D shapes would not be constructed without any connections.

As explored before, image sampling would have an importand effect on the outcome patterning, therefore changing the image of the will help me further understand each values of the definition.Some of the images require larger radius of the circle, some require more uv value on the unrollbrep.Aesthetic: 4.5Control: 4Practicability:4

Apart from the image sample, the Brep on which the circles are referenc ing , is a lso important. A s s h o w n i n t h e definition, UnrollBrpe is used in Grasshopper as a beginning, therefore the brep which used to unroll are limited.The requirement of an unrolled brep is that there are no overlapping surfaces after unroll.As a result, different s h a p e s w o u l d b e produced but some of them could not show the patterns.Aesthetic: 4Control: 3Practicability:4

Point charge and field line is hard to control because there are too many values in the list and the software could easily fail if there are more work in progressing. In addition, the position of point charge and the point for lines to go through are important, as the result in the second picture would happen.Aesthetic: 2Control: 2Practicability: 1

When I change the point charge to spin force, the lines begin to form interesting shapes.Unlike the iteration in case study 1, this project is in 3D shape, therefore spinforce would effect better to the lines.Aesthetic:4.5Control: 4Practicability: 3Sp i n Fo r ce w i t h

The iteration below contains 2 spinforces in different orientation, The image on the right hand side is produced using pipes over the lines.These iterations shows how much a project can be pushed and how we could think of our design using software.

B.5 / B.6PROTOTYPES

&PROPOSAL

In this section, the prototypes are cons idered and tested w i th the combination of the design proposal, after analysing the information on the site, the use of my researched technology is referring to my initial thoughts and things I discovered on the site.

SITE- CERES ENVIRONMENT COMMUNICATION PARK

playspace

energyparkentrance

When I walk around CERES Park, I found many places a little messy, although the market and the gardens are really attractive. Among these places I think the bike shed is more impressed to me. There are many people using that space and the picture in the middle shows that the area is really messy with all old bikes and the tiers. Therefore I was thinking creating something to hide this area.

A f t e r d o i n g t h e r e v e r s e engineering, I thought I may also use circles in my own design. When I walk in the park, there were lots of spaces where bike wheels appeared. Along the road or even a tree house is constructed by a bike wheel looks like the bike shed.

Referring the tecchnology that I explored in the case studies, image sampling is important, to choose an image for the sample, I choose tyre patterns

W h e n I t h o u g h t a b o u t t h e connections, I thought of the wheels of the bike, the strings are connected by a central axis. so I tried to create connections in my design like that. If I use strings, the connection between each cylinder would be weak, but when I use panels, even with the same pattern on the top view, it will be more connected when we look perspectively.

For the detail of the connection, I choose a mechanic way. Because I t h i n k t he pa rk i s about energy saving and fr iend ly to the environment, a simple way may refer to this idea better.

B.7LEARNING OBJECTIVE

&OUTCOMES

I f ound th i s part rea l l y he lp students understanding more about conmutation design, also push students to develop the skills.When I was doing this part, I have better understanding of the concept of Grasshopper and be able to use my understanding to support my case study and design thinking.In addition, while looking at other students' work during the interim presentation, I find that although we are doing same area of researching, prople are able to come up with really different ideas, I think this may be the interesting point of learning computing and pushing each project to it's extreme.
