FourierPlanarCoil.to_SplineXYZ(knots=None, grid=None, method='cubic', name='')Source

Convert coil to SplineXYZCoil.

Parameters:

• knots (ndarray or "arclength") – arbitrary curve parameter values to use for spline knots, should be an 1D ndarray of same length as the input. (input length in this case is determined by grid argument, since the input coordinates come from Curve.compute(“x”,grid=grid)) If None, defaults to using an linearly spaced points in [0, 2pi) as the knots. If supplied, should lie in [0,2pi]. Alternatively, the string “arclength” can be supplied to use the normalized distance between points.

• grid (Grid, int or None) – Grid used to evaluate curve coordinates on to fit with SplineXYZCoil. If an integer, uses that many equally spaced points.

• method (str) – method of interpolation - ‘nearest’: nearest neighbor interpolation - ‘linear’: linear interpolation - ‘cubic’: C1 cubic splines (aka local splines) - ‘cubic2’: C2 cubic splines (aka natural splines) - ‘catmull-rom’: C1 cubic centripetal “tension” splines

• name (str) – name for this coil

Returns:

coil (SplineXYZCoil) – New representation of the coil parameterized by a spline for X,Y,Z.
