Description

Creates an isovist at a specific point. To create an isovist with two points (one the origin, the other the direction) use isovist2pts. makeIsovists is a helper function that creates and imports multiple Isovists

Usage

isovist(graphFileIn, graphFileOut, x, y, angle = NA, viewangle = NA,
        cliPath = getDefaultCLILocation(), verbose = FALSE)
isovist2pts(graphFileIn, graphFileOut, x, y, toX, toY, viewangle,
        cliPath = getDefaultCLILocation(), verbose = FALSE)

Arguments

`graphFileIn`	The input graph file.
`graphFileOut`	The output graph file. If ommited will use the input file.
`x`	The x-value of isovist origin point.
`y`	The y-value of isovist origin point.
`angle`	The angle defining the view orientation of the isovist (in degrees, for partial isovists).
`toX`	The x-value of a second point showing the direction of a targeted isovist.
`toY`	The y-value of a second point showing the direction of a targeted isovist.
`viewangle`	The angle defining the view range of the isovist (in degrees, for partial isovists).
`cliPath`	Optional. Provide the path to a different CLI.
`verbose`	Optional. Show more information of the process.
