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.

Cylinder: • Formed by parallel lines • Rulings are also parallel • Constant section • The unfolding of the prism is the limit of development of the cylinder surface Cone: • All lines from a profile curve connect at a point • Section varying in size • The polygon at constant distance from a point A is the limit of intersection curve and a sphere with same constant distance and a midpoint of A Tangent surfaces of space curves: • The face planes of polyhedral model is the limit of the tangent surface of vertices.

• Tangent surface of vertices is tangent to the surface along an entire ruling

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.

Taking ‘California: Stage set for John Jasperse’ as an example, it is possible to understand how understanding of development surface effects the architectural geometry. This architectural geometry is particularly made to move along with the dancer thus the most flexible shape was desired. The solution was to join geometric shaped segments that can transform in to variety of forms. Since developable surfaces was in geometric shapes, it allowed them to dismantle and reconstruct easily which also meant that it could be put into a small box after dismantling for more mobility.

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?

Digital fabrication is a process that connects the design with the production. It speeds up the process by reducing the processes between design and final production. Types digital fabrication are: sectioning, tessellating, folding, contouring, and forming. The understanding of two-dimensional representation didn’t change much by intervention of digital fabrication. It simply replaced what was done in physical apparatus with three-dimensional computing system. However, now that it can be done on computers it allowed two-dimensional representations to be replicated thus making the representations more mobile and flexible.

Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design?

First reason could be because folding can create visually appealing yet economical structure. Since folding can give stiffness and rigidity to the material that are being folded without using excess systems to hold up the form, it gives a uniform clean look. Moreover, this technique can be used in multiple scales. Second reason could be the ease of manipulation to the shape through the use of computer.

It also allows to create more complex and subtle geometric shapes by the use of computers. Allowing the designers to control forms through folding more flexibly.

EXPLORING 3D PANELLING

3D objects used (from bottom to top: NURBS, Triangulated NURBS, Mesh). Bottom face is a square and triangle, square, octagon is used for the face on top.

The theme of the design is geometric shapes creating organic 3D objects. Faces on top are rotated so when loft is applied it automatically create a smooth organic shape.

The centre object; has a heptagon on top, placed at the center, and is the tallest among the other 3D objects. Meaning that this object is the main object in this model. Even the curve attractor was used to emphasize this idea (objects gets shorter towards the centre.) 2D panels are also placed so that empty space is concentrated towards the center.

Final design.

APPENDIX

Base of first idea

3D paneled first idea. Main theme was to create organic shaped objects. The shape is based on the design of Tokyo Skytree in Japan.

10

3D paneled second idea. Main focus was to make it stand out. Tried different techniques and placed together, which ended up with a chaotic look.

Lined up unrolled 3D panels. Starts from top left to bottom right
