mpas_tools.vector.Vector.intersection¶
- static Vector.intersection(a1, a2, b1, b2)[source]¶
Based on https://stackoverflow.com/a/26669130/7728169 Find the intersection point as a unit vector between great circle arc from
a1
toa2
and fromb1
tob2
. The arcs should have already have been found to intersect by callingintersects()
- Parameters:
a1 (mpas_tools.vector.Vector) – Cartesian coordinates of the end point of a great circle arc. The types of the attributes

, andz
must either benumpy.arrays
of identical size for all 4 vectors (in which case intersections are found element-wise), or scalars for at least one of eithera1

.a2 (mpas_tools.vector.Vector) – Cartesian coordinates of the other end point of a great circle arc.
b1 (mpas_tools.vector.Vector) – Cartesian coordinates of an end point of a second great circle arc.
b2 (mpas_tools.vector.Vector) – Cartesian coordinates of the other end point of the second great circle arc.
- Returns:
points (mpas_tools.vector.Vector) – An array of Cartesian points on the unit sphere indicating where the arcs intersect
