a vector field on the sphere given by a callable of the directions, the bandwidth a hint for its harmonic expansion

Syntax

vF = S2VectorFieldHandle(lambda v: v.cross(vector3d.Z))

Input

fun callable receiving unit vector3d directions and returning one vector per direction
frame referenceFrame of the query directions, or None for frame-free directions
bandwidth harmonic degree used when approximating the callable; default defaultS2Bandwidth preference

Members

eval the vectors the callable gives at the directions x, vF(x)
fhat the coefficients of the harmonic expansion of the field at its bandwidth hint
rotate the field rotated by r, v’(xi) = r v(r^-1 xi)
S2VectorFieldHandle a vector field on the sphere given by a callable of the directions, the bandwidth a hint for its harmonic expansion
