gnomonic projection

Scales the radius by tan(theta), the projection from the center of the sphere onto a tangent plane. Great circles become straight lines, but only one hemisphere can be shown and it grows without bound.

Syntax

sP = gnonomicProjection(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

sR sphericalRegion the projection is restricted to
pC plottingConvention, which direction points east
antipodal identify v and -v
