Readings Algorithmic thinking in parametric modelling. Algorithmic The basic objective of this exercise is to make a parametric model.
Human activated by having a walking pathway and a modular system that could cater to human movement. The modular system needs to have the ability to allow wave to flow through at the same time creating a joint that allows human to move without falling off the movable platform.
Human activated by an interactive system whereby the square plates could go up and down as shown on the above picture on the left. The idea is to create movement that could save wave energy. The picture shown on the right has a similar approach but it moves left and right depending on where human stands. Apart from that, the vertical frame around the platform, it creates an interesting outcome whereby it reflects the human form.
Wave energy need to be collected via the movement of the waves. It also have to be floated on top of the water to incorporate human movements as well. Taking into considerations of the highest and lowest water differences throughout the year.
Wind energy needs to be incorporated in the building. Our design intention is to create a panelling system in which there are few sides that will have these features due to the wind direction.
Definition of Tessellation is a flat surface is the tiling of a plane using one or more geometric shapes(tiles), no overlaps, no gaps, repeated pattern.
Form of the installation: Computational hanging chain models to refine and adjust the profile lines Form

Design Intention: The amount the petal dishes, and its size (the petal shrinks in plan) has a unique geometry that needed to be calibrated to fit into the overall form. Each cell behaves in a slightly different manner based on its size, edge conditions, and position relative to the overall form
Towards the base and edges: less offset, flatter where they gain density and connect to purely triangulated cells. On the interior and the top: greater offset, and more curvature to create the dimpled effect. Construction: Use Rhinoscript to instantiate each of the 2,300 petals Digitally modelled the three dimensional petal geometries Unfold each petal for laser cutting Finally, the petals are reconstituted by folding along the curved score lines, and simply zip tied together.
FORM The development of dynamic architectural concepts, digital tools as Grasshopper for Rhino and RhinoScripting, the utilization of sensor technology and dynamic light control in the software, and to work with digital technologies and interactive urban environments on a conceptual level. INSPIRATION The concept mainly focused on drawing attention from the unsafe park, and ensuring the feeling of a safer environment for the visitors.
Developed advanced spatial systems for organizing and articulating new social complexities, and at utilizing and adapting different advanced digital design methods for exploring various principles of form generation and advanced production.
CONSTRUCTION The surface is then dissected into 32 vertical and 4 horizontal struts by using Grasshopper to define a structural waffle-system. The system allowed us to connect the different struts, by merely sliding them into each other – the size of the gaps in the struts and the character of the MDF, meant that they interlocked and were kept fixed. With the CNC-milling machines’ material dimension limitations of 2,4×1,2 meters, and with some of the struts reaching lengths of 6,5 meters – the individual struts had to be dissected into shorter fragments. A puzzle-joint made in Grasshopper was inserted between these fragments. To ensure static stability, metal-plates were bolted and screwed around the joint itself.

The first few steps of getting a form is to design a curve from rhino. While using grasshopper, the drawn curve into a curve component. The curve would then need to be lofted. The surface then needs to be divided to create a waffle system. Then interlocked the model horizontally and vertically. Inserting of panelling then begin. To split the square into pieces. Using the number slide to rotate and toggle the direction to create a rotating panel.
DESIGN CRITERIA:
1. Safety for viewing public and for educational activities that may occur on site
2. Constructible, Manipulatable, Changeable (with different combination using the basic principles) and expandable (can be unrolled and incorporate preferences materials) OR Abides by basic tessellation principles
3. able to Integrate a renewable energy technology (wave, tidal and wind, filter for water)→thickness of small components AND ability to Collect and continuously distribute clean energy to a grid connection point to be supplied by the city
4. Walkable with opening on top AND Aesthetically Pleasing: eye catching, visually interesting
The use of only square grids do not allow movement diagonally thus we created a triangular grid to allow better movement. Create panelling that could create and up and down motion when someone walk on it. This is to create a system that could be used for wave energy collection as well as to create an interactive space for humans. This panel could also be used for education purposes in terms of how this system has multiple use. Taking into consideration of the material and density of the product. This system needs to be able to stay on top of the water.
From the matrices that we have created, it has more irregular pattern on the design thus we decide to create a trapezium shape to see if it is working similarly to the previous design.
This is an interlocking joint between two floor panel. It has to be able to piece with each other perfectly. Once it is piece together, it needs to be able to stay connected thus the use of a horizontal join through the interlocking system. The horizontal join then needs to be extended over to a central circular piece that would keep it connected to other horizontal pieces. The overall picture of how this panel would work as a whole. The interlocking joints would need to be connected to the central circular piece (in dotted) to prevent the other joints from getting disconnected and break apart.
This is how the central circular piece suppose to be connected between the floor panel as well as the sea bed. There needs to be a spring connected underneath the floor panel to create up and down movement throughout the human activated floor panels. This would then allow movement on the wave underneath the floor panel.
3D prototype of the central connection. Spring included to provide the control movement of the floor panels.
Connection of all the floor panel joins. Interlocking joints as well as central joint to connect to the circular central joins.
Tilting
Test: • Model incapable of standing without tilting to the side • Top fins are too big which cause main structure to tilt
Not as strong
Test: • Unable to withstand extra weight on it – still tilting • Top fins are too big which cause main structure to tilt Adding more vertical support to make it stronger
Cross Rib
Test: • Unable to withstand extra weight on it – still tilting • Cross rib bracing works better than without cross rib
Bending (not strong to hold the structure)
T column used for better support
Lap joint is described as a complex family of connections that extend the apparent length of the connected timbers. Lap joint overlaps halved members with transverse connectors transferring the tension force in one member to the next, through single shear forces. The available strength of these simple lap joints is immutably limited to less than half the gross tension capacity of the members. The net section of the lapped portion is only half of the gross.
Joint 01
Joint 02
Joint 03
Lap joint will be used in the final form of the model. Due to the curve structure that we are making, each lap joint differs from the rest to create a curve structure.
Timber is made from carbon to convert the wood into trees which then reduce the amount of greenhouse effect in the structure. It is a natural insulator and can reduce energy needs.
Timber material will be used in the final structure form as it is natural. It is safe to handle and touch, it does not break down into environmentally damaging materials.
Timber is versatile and can be used in a wide variety of ways. Being light, it is easily installed and can be worked with simple equipment.
Since we are having element that forms that is transitioning from rectangle to square to triangle, we are planning to create a wind panel that allows the center piece to rotate according to the wind. It will be situated only at certain portion of the structure. The material of the triangular frame would be made of timber to blend in with the other material of the form. However the turning blade would be made of thin white lightweight steel material to blend in with the structural framing.
Steel is inorganic whereby it will not rot, split or crack. This is a good quality as the wind turbine is going to be moving most of the time. Durability is key. Apart from that, it is easily disassembled for repairs, alterations or relocation. This is also a good advantage point, should there be a need to change if it is broken. Steel is also 100% recyclable to touch on sustainability in the building. Steel also slows down the aging process with less maintenance.

Density of form throughout the site
The density throughout the site needs to have a transition between the land and the water. Thus, following the movement of the surrounding, the density changed from less dense to more dense flowing from land to water. Human activated mechanism that allows the movement to collect wave energy. The system has the ability to move up and down in response to where someone steps. This triangular shape would be at a taller height to incorporate wind energy saving device. This would be one of the structural frame that would hold the structure up.
This is a rough sketch of how our wind energy saving device going to look like. It is basically connected to a main structure frame as shown in the above image.
This is the rough sketch of how our structure would look like. An opening to cater for the taxi terminal. At the opposite side of the form also has an opening that cater for future use of boat parking. This form is designed in such a way that it does not have to be demolished due to future changes such as the boat parking.
This form shows the density changes from the right to the left. The main reason why the left structure opens up and has a higher height because we are opening the view to the mermaid structure at the other side of the river. This caters for students and visitors for education purposes. Apart from that, we could input the wind panelling system as the wind flows from South-West to North-East. This form has a high advantage of developing to its site context. However, after the presentation with tutors feedback, we realised that this form is too massive and heavy when you were to put it on site. Thus, we take into consideration of the shadow casted by the surrounding buildings as we plan to create a siting place throughout the form. We also decided to tone down the amount of elevated form to minimize the density of the form. We also decided to create an adventurous journey whereby the users could not see the mermaid when they first enter the form. They could only view the surroundings until they reach the last point where it is the view of the mermaid. This journey is a good educational purpose as they explore the surrounding and the main focal attraction. We also want to implement seating areas facing the mermaid to maximise the time spent viewing the mermaid.
The form do not look as massive as it is previously on the site. We tend to control the area on the site depending on the site response that we have gathered. It shows the density changes throughout the site from the surrounding building and towards the water. The form changes from a very organized rectangular panel to an irregular triangular panel as it moves the transition moves toward the water.
The form does not overlaps with the shadow as the form that we are building is suppose to be very interactive with the users. Denmark weather throughout the year is constantly cold. The highest temperature throughout the year is 22degrees. It is particularly logical to create a seating area that is open to the sky. The sun would heat up one’s body despite of the cold temperature.

This is one of the openings from the structural element. This opening caters for the taxi terminal that is existing on the site. There are openings on the structural element to allow sunlight to pass through that brightens up the space. It is supposed to heat up the space with the heat from the sun. In this structure, small openings and gaps are being implemented such as slit of openings. This contributes to the element of surprise in the architectural journey.
This is another opening that caters for people who would park their boat. Apart from that reason, the opening is created here due to the expected pedestrian flow within the site. It is also due to the wind. This part needs to be open to allow wind to flow through from the South-West direction.
