earthHides関数
リファレンスの説明と例は英語です。見出しと目次は日本語です。
Whether the Earth hides a satellite. The Earth is the unit sphere at the origin. True when the line from the camera to the satellite meets that sphere before it arrives. A graze at the limb is not hidden (the line only touches the sphere), and neither is a satellite in front of the Earth. This is not the test for a satellite behind the camera.
