As of DM-13509
lsst::afw::geom::SpherePoint now uses
sphgeom vectors instead of
SpherePoint.getVector() returns an
SpherePoint can be constructed from an
lsst::geom::Vector3d (which is more general than a
UnitVector3d, in that its norm need not be 1).
In the rare case that you need an
SpherePoint::getVector I also added C+±only function
lsst::afw:;geom::asEigen which will convert either
sphgeom::UnitVector3d to an
Note that this eliminated all usa of
lsst::afw::geom::Extent3D from the DM stack. Expect a future RFC to get rid of those classes.
