jday

)

Get the moon's direction at a certain time.

Parameters:

jday

astronomical julian day.

const Ogre::Real caelum::SolarSystemModel::getMoonPhase

(

LongReal

jday

)

Fake function to get the phase of the moon

Parameters:

jday

Julian day

Returns:

the phase of the moon; ranging from 0(full moon) to 2(new moon). The calculations performed by this function are completely fake. It's a triangle wave with a period of 28.5 days.
