Find the intersections of the plane defined by the normal n and the
distance d expressed as a fractional distance along the side of
each triangle.
compute.intersections.sphere(phi, lambda, T, n, d)Latitude of grid points on sphere centred on origin.
Longitude of grid points on sphere centred on origin.
Triangulation
Normal of plane
Distance of plane along normal from origin.
Matrix with same dimensions as T. Each row gives
the intersection of the plane with the corresponding triangle in
T. Column 1 gives the fractional distance from vertex 2 to
vertex 3. Column 2 gives the fractional distance from vertex 3 to
vertex 1. Column 2 gives the fractional distance from vertex 1 to
vertex 2. A value of NaN indicates that the corresponding
edge lies in the plane. A value of Inf indicates that the
edge lies parallel to the plane but outside it.
