start to realize the power of digital techniques on the design, they do not just design based on existing things, but also can base on parametric and algorithm, that means we use the mathematic process to generate rule-based products that we do not know what it looks like at the beginning. In module 2, all of the shapes are not designed but calculated. Since I start to know the power of GH, I’m now very interested in learning it, because it’s very hard software so I still have a long way to go. but the effects are stunning.

Precedent Study M1- M Pavilion

Diagramming Design Precedent M Pavalion is a place for people to experience with all their senses, to establish a relationship with nature, but also a space for social activities and connections. Adding significantly to transnational dialogues on community and urban liveability, “where movements and routes intersect and exchange, spaces where people identify as part of a community, but also feel they belong to universality,” The MPavilion itself is a geometric configuration assembled in two distinct halves supported by a central steel portal frame. Two surfaces of timber latticework intersect with each other to form the pavilion’s roof. An altered topography forms three mounds that incorporate seating, allowing a multitude of experiences: dynamic, spontaneous and collective.

2. Tree Growth 1 geometry testing

Task A - Design Matrix

In the matrix part, I explored through the iterations of basic geometries,scale with series factor, rotates,

CUBE X=Y=Z=25

CUBE X=Y=Z=25 scale factor=1 move=50

polygon segment=6 R=25 Z=25

scale factor=1 move=50

scale factor 1=1 scale factor 2=1.4 move=50

scale factor=0.7 move=43

growth, point attractor.

My main parameters are based on the scale, to adjust to a suitable size. In my point of view, ‘succesful’ iteraion means the geometry has both empty and solid spaces, so that

people can use in an architectural point of view. Plus, the geometry need to be enough detail to show the threshhold. Finally,the geometry should have accessible spaces, we can rotate the geometry to test the possibility of spaces. For my succesful geometry, I think growth and line geometry are more helpful.They are more tend to form

FInally, is shows like this. I’m very happy with the shape, but the edges are too thin, and when I want to union it, it always fail, that’s why i gave up.

ROTATE=DEFAULT

After drag it out, it looks like this. What I did then is Delete the pieces manually.

Iput the box inside the model, what I did here is actually not boolean difference, I used split instead, and then pull it out.

4 test with 2 type of geometries

Growth and Aggregation Iteration 1

the threshholds that shows the interior space with a a rugged and rugged shape

the private unit hole space that people can use. the threshholds that shows the interior space with a a rugged and rugged shape

the private unit hole space that is penetrating to outside. the path way inside of the geometry for people to go through, create a circuation inside the forms.

The first iteration explored through the growth of the same cubic but different scale. It has a pathway inside of the geometry for people to go through, and it has a very rugged and porous feeling as theirs many thresholds. and it is a relatively exposed structure, as well as there are some units for private space.

Growth and Aggregation Iteration 2

holes for shadow to come through and cast on to the surfaces. spaces with shield overhang on top, people can sit inside the space

hidden inner space, provide private hidden space for people avoiding the crowd and light.

sloped space inside the block, provide more privared space without light.

10 mm scale at 2:1 @A4

open sloping area embeded inside the plock, for for people to lean on, this space allowed light come in. This iterations shows a very interesting and rigid shape, for me it feels more like craggy rocks with high tension. It contains several interior spaces of different size and direction. some are penetrable, so the light and wind will come through them and show some shadow pattern in the threshhold. 9

Growth and Aggregation Iteration 3

are from back, for people to sit and watch the stars. exposed from the left of this page, with hangover on top, so the light won’t come in but still can feel the wind.

hidden area blocked by a low wall, half sheltered, children can play and talk under it.

the smooth fairshaped arc provide provide people lie down and enjoying from the sunshine coming through.

blocked space inside the building, provide enough privacy. ground area, private spaces for people to rest.

10 mm scale at 2:1 @A4

For this geometry, I want to explore through more dynamic and soft shape, so I chose the ellipsoid as the basic geometry to cut it. And I consider it quite successful based on the confortable interior space for people and the overall detailed thresholds on it. This geometry is more permeable and porous than previous 2 geometries, so the light and wind will be more smooth and fluent in this shape, make people feel more relax inside this space.

Key iterations and photographys

For the first design eteration, this shape has a path way inside of it , and it has a lot threshholds.As you can see, I used growth in this process.

medium-to-latge scale for this one, I choose medium-to-large size of scale, so the small cubic interior can be occupied by people who need it. and the main circulation can show in this scale. For this scale, the interior can have a sense of volume with ragged plain surfaces with right angle.

The second iteration explored through the line conditionals, with two different kinds of boxes aligned to a curve, I cut it with a rotate cube and it shows a very interesting and rigid shape. It has many rectangular holes from all around and from top as well.

for third one, I used 2 different sphere as basic geomatry alignred to curve, to show the polyporous permeability of my shape. I used the curve conditionals to made this type of geometry.

medium dcale For this one, I choose medium size as well, cause I feel like medium size is more usable for this shape, it shows much fun to climb and use these soaces. There are many small and big rectangular shaped holes with different direction, and there’s some inner private space for people to gather.

medium scale For this space, I choose medium space, so people can actually sit and lie down to rest. If the scale is too large, it won’t have that function. It provide shade under the private space, whether it is place for sit or lie down. There’s more holes inside this sapce, so the volume is lighter, and it is more transparent than the first two iterations.

Task B - Design Matrix

For this part, i tried through the iteration of distance changes between each layer and rotate my geometries. I want to acchieve the middle sparse and the sides dense. I failed doing it by function, so I just do it manually on panel. After I finished the iteration panel, I baked then. but for first two geometry they are not succesful on showing the details. But I tried XY waffle on third one, is turns to be very effective and successful, so i choosed my third one for XY waffle. Moving on to radial waffle, I tried on every geometries, but first and last one are all facing some problems and bugs so I chossed the last one.

This is the geometry I want to use at the bigining, I used boolean split and there are too many pieces that I can’t join them into one geomtry, witch is not good for 3D print, so I gaved it up, but I really like the spaces shown in it.

Third try, failed again.

First picture shows the acute point that pieces cannot join or boolean. Second is my another try, still failed.

Surface and Waffle

arch space for prople to lie down or sit, with confortable gaps between each layers. blocked some light and wind but still penetrable so people can enjoy softened sun and wind.

ground semi-private space, with light-through hangover structure casting shadow pattern on the ground.

The XY waffle shows layers of the building in both directions which makes it look very sculptural and interesting. Especially dealing with curves, gives a strong sense of dynamic and streamline on aesthetic view, with big contrast between curve and stright line. For this geometry, I tested through different Exponential variations and did it manually on the panel; and I chose a side-dense-middlefew pattern. Then I tried through different gaps in another direction and tried with different angles. Finally, I chose the third geometry for my XY waffle and testing with the proper gap to fit the scale and provide a comfortable place for people to sit or lay down. 01 2

Surface and Waffle

The radial waffle shows a rotation shape of geometry, with the middle circles to connect every piece of layers. This geometry shows an absolutely different shape compared to its original geometry(second geometry), Which I think is the power of radial waffle. I chose this geometry for radial waffle is because it formed geometry in an esthetic way, and it has many gate and platform in it. It feels like a circus to me, because of the complicated shape with canopy and middle air stage platform, and ground stage as well. Also, there’s another reason why I chose it, is because when I testing other geometries, they all turned into some problems that the form cannot show or bugs like it doesn’t cut the shape.

irregular-shaped overhangs strusture, cast interesting shadow on the ground.

irregular-shaped gate way pass through the geometry, gives a feeling of hide-and-seek play ground.

Computation Workflow

In terms of the reason I chose these two geometry, their semse no reason, based on my idea of realization, what I did is just test XY waffle and radial waffle on every geometries and choose the best suitable one, that is the basic principles for choosing iterations.

Computation Workflow

For the scale, I chose the same medium-scale as in task A, cause I think in this scale People can exploring, interact and enjoy it more. The xy structure can change the sunlight and cast patterning shadows to add fun to the entire structure.

For the scale, I chose a large scale, like the circus stage, because this is the feeling that model made to me with the right function and scale. As the bigger scale can provide people with larger venues for events and activities.

3D Printing and Laser Cutting

extimate:11h51min The process of 3D printing is not just print it out, it has much more things to deal with, Command “check” in rhino to check whether the model is a good mesh. use “repairmesh” if there is something wrong with the mesh, we can use this to repair model.

In this process, we are placing the contour pieces into laser cut template, inorder to place it correctly so that it can be print succesfully and economically, we need to put the right objects on the right layer, most need to cut fully but some need to cut incompletly so that the pieces can still attach to the board, avoiding missing out.

In the marketbot, we discovered about the difference betweeen print material and support material.

SECRET ROSEDALE Queen Victoria garden pavilion Secret Rosedale is a pure white pavilion that indicates the holy and pure character of the pavilion. Like the wedding, it evoked the calmness and purity, and romance of the space. The pavilion is sunken, hidden inside the land, it is a secret place, only you came into it and the whole site will reveal in front. The shape is a blooming white rose, all about romantic and secret mystery. It celebrates the shadow created by the hollow frame skin. The sharp skin frame is contrasted with curved linear pavilion shape, to show its graciousness and inviolability. In the skin, the lower part is more closed to provide privacy, while the upper parts are more hollow, utill the dome in the top, to show the shadow as well as connect with the sky. The main pavilion is composed of 3 spheres, the middle one is the pavilion centre for seminar and quartet performance, the other two on both sides is pointing to the direction of pathways, and also they are smaller than the middle one, working as transitional zone and provide supplementary sitting space. The pavilion is made from 4mm thick steel sheets welded together in-site. The landscape sits are made from concrete, they then painted with white matte paints.
