rgl.sphcirc {sphereplot}

Great circle generator

Description

Function to generate a new great circle with arbitrary inclinations and radius.

Usage

rgl.sphcirc(CrossEq = 0, PeakDec = 0, radius = 1, deg = TRUE,
col = "black", ...)

Arguments

CrossEq

The right ascension where the new circle crosses the equator. This should be the corssing before the Declination values of the new great circle become positive.

PeakDec

The peak declination the new great circle will reach.

radius

The radius of the new great circle.

deg

Specifies if input is in degrees (default) or radians.

col

The colour of the new great circle line.

...

Other arguments carried to lines3d.
