3.2.2 Change the overall isovist parameters

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 edges of the isovist). 

Setting a parameter affects all latter field analysis calculations and automatically resets all analysis.
