TRANSITION FROM ONE SPACE TO ANOTHER

Triangle denotes direction and amount of space (obviously always away from closest surface - which we must stay

near to travel on most direct path)

INTENSITY OF GEOMETRY (height to apex perpendicular to pathway), shown here with a dotted line from the apex to boundary of direct path, indicates a moment ideal for conversation (we tend to move to the center of space to

of the most direct path to see around a corner (I now believe this is not inherent but a spatial / design quality to be desired and utilized).

the INTENSITY OF GEOMETRY exhibited here is

space surrounding the same ‘direct’ pathway depicted in grey. This pathway forces people to move through it faster to achieve the same

variation completely eliminates the opportunity for a space of pause that could be used for conversation or simply slowing ones movement.

Circles are drawn from the medial axes as a way to de-termine the location of the walls. The walls are drawn as tangents between the circles. (need to refine method).The artworks have a set of values recorded that determi-ne there relationship to eachother and the architectural features that are shaped through the construction of this diagram.Each number represents a NODE. These NODES in turn represent an individual work of art.

2 Types of Orientation to Circulation

STUDY PROCESS model + code

Typology studies By changing each one of the parameters randomly, we endeavor the potential of each type of the geometry composition.Distance between center of the circle and direct path way is significant criteria for the topology.Thus we first categorized geometries by the distance.The classification using the distance variable is represented as e.g. “SSSS” (‘same, same, same, same’ - s = same side as first node), or “SSDS” (‘same, different, different, same’ - d = different side than first node).

In this typology, two of the types are special: SSSS and DSDS. All of the other types can be explain as a combination of these two and at the same time they cannot represent each other. It can be said that they are linear independent.

For that reason, following study on dimension change in the parameter “Length” deal with only three of the types. SSSS, DSDS(basis types) and SSDS(combination).

Analysis

Approach angle has affect locally.there are three types interms of approach angle: saw tooth, united space, look back. When the length of the pathway is changed, separation of each node is emphasized or deprecised. Length is one of determining factor of area scale thus longer wall creates lager space.In addition, when the pathway is long and distance between center of the space and pathway is rela-tively short, that space becomes shallow. In other words, the affect of approach angle or distance is depreciated.

Interms of rotation we reach to two conclusion. When 2 or more nodes are on the same side, increasing rotation unifies their space. The room becomes less faceted and more simple. And the rhythm of, what we have termed, ‘pocket’ gallery spaces is eliminated or reduced with increasing rotation. When the nodes alternate sides rotation has the opposite effect. Instead, increasing rotation makes the nodes space more isolated from those adjacent to it, both visually and spatially.

Those categories are di-vided into detailed brunch by other parameters.

2D WORKS

SSSS:

When the pathway is stretched, the entire geometry looks like saw tooth and where the length is shorter the saw tooth is keen. When the pathway is gradually winding and length of each node is short, the entire shape becomes close to circle. In other words, radius of curvature is proportional to the length. Length has less things to do with sharp corner.

DSDS:

DSDS is head-shaker type. That is a ptatron has to turn every time they move to the next node. When length is short, this turn occurs often and entire space becomes confused. If the length is longer side change is less important.

Plan System

Artwall

1. PLAN2. Artwall = Highest ceiling

3. Slow Space = Lower

The diagram determining ceiling and roof height:

> Highest ceiling height is at the Artwall.. > Stopped space is also very high but slopes away from the Artwall.

> Slow space is medium height and shears the roof away from the portion created by the Artwall and Stopped space, creating an opening to bring in light. (This opening should not face south).

> Ceiling height above the Direct Pathway is the lowest corresponding to the most circulation and the fastest circulation.

>>The relationship of height to speed of circulation is; the slower the circulation = the greater the ceiling height And conversely, the faster the circulation = the lower the ceiling height
