sphere.cart.to.sphere.wedge

<p>locations of points on sphere as N-by-3 matrix with
labelled columns "X", "Y" and "Z"</p>

<p>Convert points in 3D cartesian space to locations of points on
sphere in 'wedge' coordinates (<var>psi</var>, <var>f</var>).  Wedges are
defined by planes inclined at an angle <var>psi</var> running through a
line between poles on the rim above the x axis.  <var>f</var> is the
fractional distance along the circle defined by the intersection
of this plane and the curtailed sphere.</p>

Reconstructs retinae by morphing a flat surface with cuts (a
dissected flat-mount retina) onto a curvilinear surface (the standard retinal
shape). It can estimate the position of a point on the intact adult retina
to within 8 degrees of arc (3.6% of nasotemporal axis). The coordinates in
reconstructed retinae can be transformed to visuotopic coordinates.
