The landscape has been transformed into an alien terrain. There is a curved path going through the topography, which has been surrounded by mountain like forms. At first they it was meant to be a spiky valley with spikes pointing towards the path and hanging over it. The spikes were formed of pyramids. This idea then turned into a mysterious valley with the pyramid forms opening up at the top. Inspiration was first drawn from origami flowers however, the result had a resemblance with a hatched egg from the movie ‘Alien’. Therefore, giving the terrain a mysterious and like like feel.



WEEK 6 READING: SURFACES THAT CAN BE BUILT FROM PAPER IN ARCHITECTURAL GEOMETRY Question 1: What are the three elementary types of developable surfaces? Provide a brief description. (Maximum 100 words) Cylinders, cones and tangent surfaces of space curves are the three elementary types of developable surfaces (S). The S of a cylinder will be a set of straight parallel lines which are connected to two other lines on either side, these do not necessarily have to parallel or straight. A cone on the other hand, does not have parallel lines, but lines which all connect at the vertex. Also if a cones intersects with a sphere, which gives ellipse shaped cut, its S shows a curved line.

Question 2: Why is the understanding of developable surface critical in the understanding of architectural geometry? Choose one precedent from Research/Precedents tab on LMS as an example for your discussion. (Maximum 100 words) Developable surfaces allow for complex flowing forms to be simplified into simple geometric shapes. As seen in Huyghe + Le Corbusier Puppet Theatre, which creates a flowing form with many diamond shape pieces instead of one giant complex curved piece. This decreases the construction complexity and cost, as well as giving the architecture some modularity which means the designer can change the materials or form more easily. It also allows for a wider range of materials as some materials cannot be curved or not feasible to do so.


PANELLING 2D PATTERN Below are a few iterations of 2d paneling applied to the topography. These are quadrilaterals, they do not work as the connecting panels have gaps between them. Therefore, it cannot be constructed.


PANELLING 2D PATTERN These are triangulated panels, they are able to be constructed as the panels connect without gaps.

Different shapes have been explored so a wide variety of designs can be considered. These are different polygons


VARIABLE 2D PATTERN When creating the 2d variable patterns, using the ‘Panel Custom 2d Variable’ resulted in an surface with panels that were spaced apart therefore, making this impossible to construct. Many different iterations were made to get an understanding of the different ways to achieve a variable pattern. These are a few.


VARIABLE 2D PATTERN The solution to this problem is to vary the initial grid using ‘Surface Domain Variable’ along with curve or point attractors, which would then be panalised. Attractor


3D PANEL TEST PROTOTYPE & TEMPLATE A simple 3d pattern was created to prototype. This helped with understanding the unrolling and constructing process.



Question 1: What is digital fabrication and how does it change the understanding of two dimensional representation? (Maximum 100 words) Digital fabrication is a medium that is used to represent designs before they are constructed. It uses the designs created in a digital form to be create prototypes, allowing the designer test their designs and go back and forth quickly between phyla and digital models. This also allows for three-dimensional designs to be broken down into their two-dimensional components. Therefore, designers are able to easily see the different two-dimensional parts that construct the three-dimensional object.

Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) Folding allows for a two-dimensional surface to become a three-dimensional object. This allows for interesting forms to be created while giving the material greater structural strength. Additionally, using folds reduces the cost because only a flat surface needs to be created which will then be turned into its three-dimensional form.


EXPLORING 3D PANELLING Different types of Patterns were tested to get an understanding of how they can be created. The following are basic 3d patterns.


EXPLORING 3D PANELLING A couple of designs for the full landscape were made with simple pyramid forms.

The path is represented by the 2d panels, the mountains by the 3d panels.

The split between the 2d and 3d surface was made with the idea that there would be path that goes through the mountains. (Left)

Further exploration resulted in an inverse of the previous design. Where the mountain range is in the centre with the path on the outside. (Right)


EXPLORING 3D PANELLING Custom 3d forms were explored, however, when they were applied to the landscape the forms would curve. Curved surfaces cause a problem because they cannot be constructed using materials that cannot curve, such as paper.

The solution to this problem was shown at Workshop 4. The custom 3d shapes must be converted into a mesh before the pattern was applied. The turned back into a NURBs surface to be unrolled.


EXPLORING 3D PANELLING Different custom 3d forms were explored using sketches. The ideas started with a simple pyramid, then to a pyramid with the top cut off. This resulted in a square top. The shape of the top was then adjusted, finally arriving at a star.

The final custom 3d form was then created in Rhino with different variations. Three variations were created, each one has a slightly larger star at the top.

Flaps were added to the star to create a flower like form. It also looks like a hatched egg from the movie Alien.

This custom 3d form was prototyped to get an understanding of the way it would be constructed.


FINAL 3D PANELLING The custom 3d forms were applied to the full landscape. The 2d and 3d split was created the same way the initial full landscape was designed.

A path which flows through the mountains. More 2d panels were exposed to achieve a more even split between the two.


UNROLL TEMPLATE OF YOUR FINAL MODEL As a result of the custom 3d form, each section had to be unrolled in four pieces. Then most sections could be joined together once the tabs were added. Otherwise the shapes would overlap.
