The sense of mystery in the TCPG is a by-product of structural permeability rather than visual accessibility. | The network of paths in the TCPG is very difficult to navigate and understand, but the spaces that can be seen from the paths are more intelligible. |
1) Intelligibility: being the Pearson correlation between integration and the connectivity values of all vertices in the plan graph. 2) Control: the degree by which a space controls access to its neighbours. | If the hypothesis is true, then: |
1) path-related intelligibility measures will be lower than vision related intelligibility.
2) path-related control measures will be lower than vision-related control. | |||
The visual sense of mystery in the TCPG is heightened by the complexity of its spaces. | Spaces in the TCPG have both high levels of visual mystery and of visual complexity. |
1) Isovist occlusivity: the total length of all occluded edges in a view-shed. 2) Isovist jaggedness: the ratio of Perimeter^{2} to Area in a view-shed. | If the hypothesis is true, then: |
There will be a positive correlation between spatial integration (i) and both occlusivity (O) and jaggedness (J) results. | |||
The sense of phenomenal transparency in the TCPG is a by-product of the visual pull and directionality experienced in major spaces. | The sense of transparency experienced in large spaces is caused by spatial irregularity, meaning that the eye is drawn to look deeper into the environment. |
1) Isovist area: the area of isovist polygon. 2) Drift magnitude: the distance from observation point to centre of mass of isovist polygon. | If the hypothesis is true then: |
Drift magnitude will increase in line with isovist area. |
