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) The three basic types of developable surfaces are: 1. Cylinders: cylinder’s surface (S) is formed by a group of parallel lines. To model S, a profile curve (P) is needed and then extruded in a parallel manner. 2. Cones: a profile curve (P) and a vertex point (V) is needed. A cone consists of all lines connecting P and V. 3. Tangent surfaces of space curves: the model of the developable surface is created by making a general plane which intersects the polyhedral surface in the polygon.
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 surface contributes to several important elements in understanding the architectural geometry. Accordingly, Greenhouse by Plasma Studio is an infrastructure which is created in relation to the landscape surrounding it which utilized the idea of paneling using developable surface. By using developable surface, the workload and cost was reduced; this is due to the nature of the construction material, glass and steel beams, which are arguably hard to be shaped in certain ways. Furthermore, it creates a geometric pattern which gives a dynamic effect on the structure.

VARIABLE 2D PATTERN The star pattern is arranged using scale as the pattern method, and the distribution method is point attractors. This made the star smaller as it is located further from the selected point, which is on the middle.
Using another star pattern, the pattern is arranged using the same pattern method. However, the distribution method for this pattern is using curve attractors; causing the pattern to change shape depending on the selected curve.
Despite using the same pattern as the previous example and both are using curve attractors, the pattern changes significantly due to using rotation as the pattern method.

WEEK 7 READING: DIGITAL FABRICATION Complete your reading before attempting these questions:
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 which narrows the boundary between representation and actual constructs. However, despite CAD, as an example, replaces drawing with parallel rule and lead pointer, the result remains the same. This is because digital fabrication merely took a form of two dimensional representation and replaced it with another. Three dimensional computer modeling and digital fabrication energized design thinking and expanded architecture and construction.
Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) Two reasons why folding is used extensively in building design are: Firstly, folding can give a structure stability, can span far distances and self supporting. As a result, structures are cheaper economically and materially, visually appealing and the efficiency is at any scales. Secondly, folding expands the idea of three dimensional surface. This is caused by the nature of folding itself, deformation and inflection.

EXPLORING 3D PANELLING
The panel created above uses curve attractors to offset the initial points. Then the custom 3D variables (shown above as dark green) are panelled to the points. Point attractors is used on one point on the center of the landscape, thus the pattern follows. The panels are inspired by real landscapes, where mountains which are relatively flatter on top are generally located in the middle of the sharp, dense canopy of the forest.

UNROLL TEMPLATE OF YOUR FINAL MODEL
Shown above, the unrolled template of the final model, originally in 3 pieces of A1 paper. Some of the panels cannot be unrolled properly without overlapping each other, so splitting some objects are necessary so that the panels do not overlap each other.
