Grid of vertical distances from points in the rotor circle to its horizontal axis
Source:R/generate_rotor_grids.R
get_y_grid.RdTaking the center of the rotor circle as the origin,
get_y_grid generates a grid of vertical distances \(y\) (by
yinc increments) from the x-axis to the outer edge of the rotor
circle, across width intervals \(x\) (by xinc increments) between
the center and maximum rotor width.
Returned grid represents the left-half of the rotor's circle.
Distances are expressed as proportion of rotor radius (i.e. \(y\) is dimensionless).
Arguments
- x_grid
A 2D array, with horizontal distances from the rotor's vertical axis, expressed as the proportion of rotor radius, for the left-half of the rotor circle area.
- yinc
a numeric value, the grid increment along the y-axis
Value
2D array giving a grid of vertical distances \(y\) from the rotor's horizontal axis, expressed as the proportion of rotor radius, for the left-half of the rotor circle area. Negative values represent distances from the bottom half of the rotor circle.
Examples
x_grid <- get_x_grid(yinc=0.05, xinc=0.05)
get_y_grid(x_grid,yinc=0.05)
