rotate

acstools.utils_findsat_mrt.rotate(origin, point, angle)

Rotate a point counterclockwise by a given angle around a given origin.

Parameters:

• origin (tuple of float) – (x, y) coordinates of the origin about which rotation is centered.

• point (tuple, float) – (x, y) coordinates (in the unrotated reference frame) of the point whose new coordinates (in the rotated reference frame) will be calculated.

• angle (float) – Angle of rotation in radians.

Returns:

• qx (float) – Resulting x coordinate in the rotated reference frame.

• qy (float) – Resulting y coordinate in the rotated reference frame.
