Grid of horizontal distances from points in the rotor circle to its vertical axis
Source:R/generate_rotor_grids.R
get_x_grid.RdTaking the center of the rotor circle as the origin,
get_x_grid generates a grid containing horizontal distances \(x\)
(by xinc increments) from the y-axis up to the outer edge of the
rotor circle, at equidistant height bands \(y\) (by yinc
increments) between minimum and maximum rotor height.
Distances are expressed as proportion of rotor radius (i.e. \(x\) is dimensionless).
Returned grid represents the left-half of the rotor's circle.
Arguments
- xinc, yinc
numeric values, the grid increments along the y-axis and x-axis (i.e. grid cell dimensions)
Value
A 2D array giving a grid of horizontal distances \(x\) from rotor's vertical axis, expressed as the proportion of rotor radius (i.e. \([0, 1]\)), for the left-half of the rotor circle area.
Examples
