Dear space syntax community
I am writing you to ask for some help for trying to clarify some questions on
spatial analysis
regarding fields of view, making use of Depthmap software.
It seems to me that, based on the documents consulted about the software, all spaces should be
convex polygonal spaces.
1 - How to consider in multilevel spaces fields of view studies spaces that
have visibility with spaces in lower levels or higher levels (such as a
mezzanine space)
In the particular case I've
met this difficulty in
1a) in the space of FAUP library. (Fig. 1a) we should consider the upper space,
as a single convex space without barriers? How to analyse a visual control
between spaces at different levels?

1bi
) space cloister
and the circulation areas in ground floor
(Fig.
1b)
should we consider galleries and the empty central place as a as a single square convex space without barriers?

space cloister and the circulation areas in first floor
(Fig.

should
we
consider galleries and the empty central place as a as a single square convex space without barriers?
2)
2) Wen we are studing a spoace considering isovist fieds of
view in a building should we consider the windows as visual permeability
between spaces?
If a physical space is defined by a totally transparent barrier, such as in fig
2a
should
all space atrium and secretary be considered as a single convex space
for fields of view analisys, but for axial analisys the spaces should
they
be
considered as 2 separated convex spaces?

In Carlos Ramos Pavilion in FAUP,:
i)
how to consider the visual continuity between all
spaces on the same level,
ii)
ii) how to consider the visual continuity between spaces
different levels, such as in the groud floor and the first level

3) If a physical space is defined by a barrier with a high that does not
interrupt the visual permeability. Like situation of the service desks in
departments, or handrails, which forms a physical barrier to mobility but as physical
elements with an approximate 90cm height they does not constitute visual
barriers for users. Fig

fig3
4) situations ramps / stairs that high should we consider cutting visual
permeability between floors, the same as
we consider when we represent the space in plans (~1,1 m)?
