Find perpendicular forward distance to a parallel surface.
Find perpendicular forward distance to a parallel surface.
Throw an exception if the other surface is not parallel.
Assuming the other surface is parallel, the distance is simply the w-coordinate of the other surface, and is signed.
Arguments:
surf - Other surface.
Returned value: Distance.

Calculate difference of two track parameter vectors.
Calculate difference of two track parameter vectors. This method has a default implementation which is just the numeric difference. Surfaces that require a more sophisticated difference (e.g. phi-wrap difference) should override this method.
Reimplemented in trkf::SurfYZLine.

Test two surfaces for equality, within tolerance.
Test two surfaces for equality, within tolerance. Here equal is defined as having all surface parameters the same, not just having the surfaces coincide spatially, so that the local coordinate systems are the same between the two surfaces.
Arguments:
surf - Other surface.
Returned values: true if equal.
