Earth and Orbit (working title: sattracker) is an ios swift project for visualising the earth and stuff that's orbiting it using SceneKit.
The Orbit class creates a 3D "line" for visualising an orbit path using perigee, apogee and the inclination of the orbit.
// Draw ISS orbit
let orbitNode = Orbit(apogee: 410, perigee: 408, inclination: 51)
parentNode.addChildNode(orbitNode)
