equal area projection of a hemisphere onto a square

The Lambert projection folded onto a square rather than a disc, so that a regular grid in the plane is an equal area grid on the sphere. Used for the square master patterns of dynamical simulations.

Syntax

sP = squareProjection(sR)
[x,y] = sP.project(v)
v = sP.iproject(x,y)

Input

sR sphericalRegion the projection is restricted to
v vector3d
x, y plane coordinates

Class Properties
