Above: Finding optimal routes through an area field in Mies’ Barcelona Pavilion Once an isovist field analysis is stable, it can be used to derive optimal routes through the space, either maximising or minimising exposure to the respective field measures. To do so: Below: A Control field in Barcelona’s grid plan
The metric depth to location at any point ‘V’ in plan is the shortest metric path distance from said point to a single universal sample location. The mean metric depth at any point ‘V’ in plan is the average metric distance from the point to all locations (Hillier, 2009). In an isovist field form it […]
Directed Visibility (Wv) expresses the proportion of the user defined subject region that a location can see, or, inversely, how often a location is seen from said region. Isovist_App Directed Visibility correlates to Area and Connectivity when just accessible space is analysed; but varies, introducing a degree of direction, once the sample region is restricted […]
Below is the edited text and slides of a lecture Sam gave to the UCL Space Syntax Laboratory Research Seminar on 25th February 2021. Titled ‘Integration without the grid; An isovist based approach to spatial analysis’ it reflected on the work underpinning the isovist app, and discussed themes around the calculation of a key metric […]
Sometimes errors in a drawing are only spotted after import and need to be fixed; or users may wish to test the outcome of spatial interventions to an analysis result. To allow this, the Isovist_App includes a basic set of drawing editing tools. To edit an imported drawing: Open the ‘Drawing and Setup menu’. Select […]
A series of parameters can be set for isovist calculation. Each parameter is controlled by a slider in the isovist analysis menu as follows: Isovist sweep (angle of view). Direction (heading that the isovist is ‘looking’ in). Far rim (how far the isovist can ‘see’). Near rim (an internal horizon that sets the nearest visible […]
Changes in 2.4.9 [ 01_02_24 ] – Extension of licence to September 2024– Addition of spatial wobble metrics of mean variation, standard deviation variation, and coefficient of variation, and live plots of wobble characteristics– Addition of time-to-contact array overlay– Addition of motor containment metric– Fix to point isovist positioning to allow floating point precision Changes […]
Our next guest is Greg Maya, who Sam has been talking to about all things isovist for some time. In 2019 he was awarded British Council Fellowship to explore the works of Rogelio Salmona in Colombia. Here he tells us about his use of the Isovist app at the heart of a series of high profile […]
February 2020’s entry is by Alice Bates, who wrote her UCA Undergraduate thesis on Hemingway’s Paris and Kerouac’s New York….. Hello, I’m Alice. I started my Architecture BA at the University for the Creative Arts in 2016 and graduated in June 2019. Prior to studying at UCA I completed a degree in Classics at the […]
