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 |
