In retistruct: Retinal Reconstruction Program

Description

Invert image of a partial sphere and scale the longitude so that points at latitude phi0 is projected onto a longitude of 0 degrees (the equator).

Usage

invert.sphere.to.hemisphere(r, phi0, ...)

Arguments

r	Coordinates of points in spherical coordinates represented as 2 column matrix with column names phi (latitude) and lambda (longitude).
phi0	The latitude to map onto the equator
...	Other arguments

Value

Matrix in same format, but with pi added to lambda and phi negated and scaled so that the longitude phi0 is projected to 0 degrees (the equator)
