Description

circle_line_intersections computes the intersections points of a given circle with the grid lines along with the angle formed with the x-axis.

Usage

circle_line_intersections(circle_x, circle_y, r, n_line, grid_lines)

Arguments

circle_x, circle_y	The the euclidean coordinates of the center of the circle.
r	The radius of the given circle.
n_line	The number of grid lines.
grid_lines	A 6 columns data frame with columns names as coor_x_1, coor_y_1, coor_x_2, coor_y_2, orient_line. coor_x_1, coor_y_1 Coordinates of the left end point of the grid line coor_x_2, coor_y_2 Coordinates of the right end point of the grid line orient_line Line orientation indicates horizontal orientation indicates vetical orientation k_line Line numbering: bottom to top, then left to right

Value

It returns a three columns data frame containing x-coordinate, y-coordanate of the intersection of the circle with the grid, and the value of the angle betweem the x-axis and the line joining the center of the circle to the corresponding intersection point.

Examples

data(grid_line)
attach(grid_line)
circle_line_intersections(2022230,-3123109,10000,39,grid_line)
detach(grid_line)
