◆ positionAtTimevInVSOP87Coordinates()

virtual void Orbit::positionAtTimevInVSOP87Coordinates ( double  JDE,
double *  v 
JDEJulian Ephemeris Date
vdouble array of at least 3 elements. The first three should be filled by the X/Y/Z data.

Reimplemented in GimbalOrbit, and KeplerOrbit.

◆ setParentOrientation()

void Orbit::setParentOrientation ( const double  parentRotObliquity,
const double  parentRotAscendingNode,
const double  parentRotJ2000Longitude 

This is called by the constructor, and must be updated for parent planets when their axis changes over time.
