Week One

Reading: Zeara Polo, A. 2010. Between Ideas and Matters.

According to Zeara-Polo, the diagram does not play a representational role in the design process but provides an organisational and can have a performative quality depending on how it is deployed. Explain how Diagram is different from Signs and Symbols? (100 words Maximum)

Diagrams, as opposed to signs and symbols, do not play a representational role for their dynamic object and mediate between physical constructs and concepts or percepts on an organisational level. Diagram is defined as a tool that describes relationships and prescribes performances in space. It does not necessarily contain metric or geometric information. A diagram is usually specific to a space , as opposed to a graph which exists in an abstract space. And the diagram relates to processes that may occur not only in three-dimensional space but in several other dimensions of reality.


Week One

Precedent Analysis



Fig.1 -- Extruding the cube and spheres from the ground plan according to dimensions

Fig.2 -- Booleaning different the spheres from the cube

Fig.3 -- Projecting the fluting onto the spherical internal surfaces of the pavilion


The modeling process of the precedent study is mainly devided into four parts which are the extrusion of the solid structure according to the dimension and ground plan (Fig.1) , booleaning the spheres from the solid box (Fig.2), projecting the fluting curves on the inner surfaces of the pavilion (Fig.3), and finally modeling the landscape. The difficult part should be making the fluting and projecting it onto the surface. The process would be described in the appendix of the journal.


Week Two

Reading: Hertzberger H. 2005. The in-between and The Habitable Space Between Things, from Lessons for Students in Architecture. Herzberger discusses how design should not be extreme in its functionality. Use your precedent study to explain how the pavilion allows for an appropriation of use. (100 words Maximum)

For expanding the posibilities of all the things we design so that they will be more useful, more applicable and so more suited to their purpose, or suited to more purposes, ‘Irregularities’ should be ingabitated in the design and the basic grammar of architecture, for example, parapets, raillings, posts an gutters should be exploites to increase posibilities of attachment. In my precedent study, the steps under the pavilion and on the side of water are used to provide seating and the internal spherical shape with different height of the pavilion can be used to rely on.


Week Two


Isometric drawing of Radix Pavilion The isometric view of the pavilion is captured from the southeast direction which shows the hardest part of the pavilion in the modeling process, the inner decorated fluting by dotted line and part of the landscape. The fluting is the detailed part of the pavilion, it imitates the contructing method of the internal spherical surfaces of the pavilion. By modeling the pavilion, i learned that the threshold of the precedent study is derived from spheres of different sizes and the circulation area and paths are basically determined by the position and the height of those spheres. The design intension of the pavilion might be experimenting the internal space with various height. The different height of thresholds might affect the behaviors of the visitors, for example, the visitor would stand, bow or sit within the space of different height. The area with higher ceiling height might suggest more circulation than the area with lower ceiling height.

Week Two Diagrams

Primary circulation area Circulation path

Circulation Diagram

Threshold Diagram

The circulation diagram is in three parts which are, from top to bottom, the pavilion, the primary circulation area (yellow shading area), and the circulation path (red curves).

The threshold diagram is in four parts which, from top to bottom, are the pavilion, the internal threshold, the tunnel (imitating the interior space with various height), and the shading zones with different openness level (gradient from bright to dark).




Placing the gound plan of the pavilion in to Rhino and extruding the solids according to the dimensions Fig.4

Using command ‘Array polar’ to array lines around a central point, then using command ‘Project’ to project those lines onto the spherical surface. Fig.

Placing the spheres into correct position to prepare for boolean

Using command ‘Boolean different’ to trim the intersecting parts of spheres and the cube from the cube



About the fluting of this surface cannot be obtained by the method in Fig.8, otherwise, the projecting lines will be as those in Fig.9.

Rotating the arraying lines 90 degree




Keeping the intersecting parts between spheres and cube to obtain the interseting surfaces to which the fluting will be projected. Fig.7

Extruding these lines to surfaces by command ‘Extrude Line’ Fig.11

Appendix Process

Using command ‘Intersect’ to produce intersection lines between the spherical surface and those planar surfaces. Fig.12
