Module 1 - IDEATION
NATURAL PROCESS: SNOWFLAKE FORMATION
Plate grows into a prism. Facets grow at a different rate under different condition.
THE FORMATION OF SNOWFLAKES
Microscopic dust particles in a cloud
Dust particles, water vapour and impurities condenses and bond to form hexagonal lattice formation
Arms grow out of corners due to instabilities.More detailed pattern is created on arms due the its faster rate of growth compared to the facets
More plates are formed under different conditions again.More arms branch out of corners due to instabilities of the plates again which create the more complex look of a snowflake
The process behind that forms the pattern of a almost symmetrical 6-sided snowflake really is something that is hard to believe and understand. Snowflake is famous for its unique shape that has 6 branches emerging out from a hexagonal plate in the middle. How do water droplets, dirt and suspended impurities in the air form into something so unique and delicate? This is something that interest me the most among all the other natural processes.It is stated by scientist that the 6-sided structure reflects the molecular structure of water that was crystallised under a cold temperature.
What fascinate me the most is how the each 'facets' (hexagonally arranged water molecules) are formed.
How each arm that branches out of the corners turn out to be so detailed when being observed under the microscope.
Snowflakes do not only consist of almost symmetrical star-like pattern. Under different conditions, snowflakes can be appeared in needle-shaped form or in plate-form.
Humidity is the largest factor affecting the shape and pattern of a snowflake. Diagram above shows the different types of snowflake formed under different level of humidity.
Self organization behaviour introduced by Ball (2012) related to how snowflakes are self organized in forming different patterns in order to withstand the different level of humidity in in order to gain stability.
When the snowflake faces with different condition, arms will branch out to gain stability.This brings the idea of fractal geometry introduced in lecture.
NATURAL PROCESS: SNOWFLAKE FORMATION
The Metropolitan Museum of Art, New York designed by Tomas Saraceno has inspired me that even a simple geometry can be formed into something abstract and unique. Also, giving me ideas for the lantern on how to build a 3D model using one simple geometry. This building Is called cloud city and the name reflects to how snowflake are formed. The shape also represents the bonding of molecules to produce a hexagon shaped facet.
I have decided to explore on the formation of snowflakes and the growing process from something small as a dust to a fully developed shape. Used Kandisky's concept (Poling: 1987) of analytical drawing from Poling(1987) to draw more underlines ideas that can be found in a simple object or geometry by focusing on the tension lines and focus point of different shapes
Besides that, using different point of views to view the patterns introduced in lectures also helped in developing my final concept.

NATURAL PROCESS: DEVELOPMENT
DEVELOPMENT: CLAY MODEL
Developing from the natural process, I explored on how to show the twisting effect of a snowflake forming in my model.
I started to think how the model would be placed around my body to show a better representation of the falling process as well as the process of it growing from a dust to a fully formed snowflake.
FINAL CLAY MODEL
Module 2 - DESIGN
DIGITISATION: CONTOURING AND DIGITISING PROCESS
I realised that it is very difficult for Rhino to loft two different curves at the same time and thus, I remoulded my final model into one solid piece thinking it would be easier to digitise. Although I managed to digitse the solid clay model, I had trouble with the size and trying to fix the twisiting effect into my model. And this is because I did not understand how Rhino works and how it functions.
Refinement of lofted model
This reflects to the reading by Scheuer & Stehling (2011) that it is important to understand the functions of a programs because every move is very precise and details and it is essential to plan out the steps needed to be taken when using a program.

Figure 2 Figure 3 Figure 4
Initially, I was facing difficulty in trying to attach the 'head' and 'tail' together as shown in figure 1. After getting some advice from my tutor, I was being suggested to change the position of the contour lines in order to allow it to loft from the bottom of one 'tail' up to the 'head' and back down the other 'tail' as shown in figure 2.
After trying that method, I managed to create my model in one surface but I was facing problems with the scale and position of the model around my body. Thus, using 'pictureframe' command, I readjusted my model until the control points as shown in figure 3 and 4.
After I've managed to get a nice and smooth surface for my model, I moved on to trying out the basic paneling options on it.I was surprised at how different it looks after the panels are on it. I've tried the box, diamond, and also some 3D panelings like pyramids.After that, I explored with the 'offset border faces' command to put holes in the panel to give it a complete look
Paneling tools has provided me an insight of what my model might look like and has given be a starting point in developing my lantern.
PANELING: BASIC 2D AND 3D PANELINGS
Using the natural process that I've chosen to explore in Module 1 (snowflake), I began to look at different types of paneling that is able to represent the natural process.
From the lecture by Dave (2012) on how patterns can be looked at in different scales, I began to explore the shapes that form snowflakes from a very small scale to a big scale.
At a close distance, spikes and needle-like shapes can be seen in a snowflake. In a larger scale, its form is bounded by basic geometry shape.
Mobius Strip by Henry Segerman
Looking back at growing of snowflake pattern, I have decided to merged the two components together to show the process
Through Rhino, I have explored with many different tools and options that can be used to develop my ideas. However, I needed to make sure that my design in the virtual world is applicable in reality at the same time.
Developing from the precedents and idea of looking at different scale,I have looked at how the model can bring different shapes into one panel to form a different perspective and composition.
Inspired by Selenitsch (2012), he talks about how abstraction and perception is important in a composition due to different culture and ideas adapted by people and this draws me to look at different composition and how different shapes and patterns can exist within a geometry.
I have built prototypes of different panels that I have developed earlier on. Using different colour and density of papers, I began to test the structure of the materials and also the shadow they would cast under different density of light. I've decided not to use black because I want to emphasize on the flow of snowflakes formation and do not want to bring a contrast to my model
Through building prototypes using different materials, I have learnt that materials are the substances that form our virtual model in reality. And it is something really important in order to form a rigid and stable model. (Fleischmann et al. : 2012)
FINAL MODEL: ORTHOGRAPHIC VIEW
Module 3 - FABRICATION
To begin with fabrication, the first step was to unroll the panels of the model. I have decided to unroll the 'head' and the 'body' in strip form while unrolling the 'tail' in a twisted form.
After solving the problems faced with unrolling the faces, I coloured the strips in different colour so that it is easier for me to identify the pieces during construction.
After that, I added the tabs manually using Rhino. I tried using Grasshopper but it did not work very well due to the tiny incisions in between the panels and also the shape of the strips.
FABRICATION: UNROLLING FACES AND TABBING
After unrolling all the faces, I used the ptTagObjects command to apply tags on each each of the panels for easier construction process as well. I also started to label each unrolled panels to prepare for cutting.
To prepare for fabrication using the laser cutter, I assigned each line to its own group in specific colour (cut-black, score-red).
I nested the panels as close as possible to maximize the use of the material and not wasting them. This is reflected through Gershenfeld (2005)'s idea ofequality fabrication as a process without waste.
For the partial prototype, I tested one two areas which I thought would be the difficult areas.
I wanted to test of the stability and how different materials would work.These two parts are quite stable although I was testing out wi
