line_equation_2d#
- regridding.geometry.line_equation_2d(x, y, x1, y1, x2, y2)[source]#
Test if a given point lies above, on, or below a line specified by two endpoints.
Returns zero if a point is on the line. Otherwise, points above the line have the opposite sign of points below the line.
- Parameters:
x (float) – \(x\)-component of the test point
y (float) – \(y\)-component of the test point
x1 (float) – \(x\)-component of the first endpoint of the line
y1 (float) – \(y\)-component of the first endpoint of the line
x2 (float) – \(x\)-component of the second endpoint of the line
y2 (float) – \(y\)-component of the second endpoint of the line
- Return type:
