Constructor Detail

SolarSystem

public SolarSystem()
            throws StellariumException

Throws:

StellariumException

Method Detail

setFont

public void setFont(float font_size,
                    java.lang.String font_name)
             throws StellariumException

Throws:

StellariumException

setLabelColor

public void setLabelColor(SColor c)

getLabelColor

public SColor getLabelColor()

setOrbitColor

public void setOrbitColor(SColor c)

getOrbitColor

public SColor getOrbitColor()

setTrailColor

public void setTrailColor(SColor c)

getTrailColor

public SColor getTrailColor()

load

public void load()

Init and load the solar system data

Throws:

StellariumException - If the planet data cannot be interpreted

computePositions

public void computePositions(double date,
                             Planet homePlanet)

Compute the position for every elements of the solar system. The order is not important since the position is computed relatively to the mother body

Parameters:

date - the julian day to compute position

computeTransMatrices

public void computeTransMatrices(double date,
                                 Planet homePlanet)

Compute the transformation matrix for every elements of the solar system. The elements have to be ordered hierarchically, eg. it's important to compute earth before moon.

Parameters:

date - the julian day to compute position

draw

public double draw(DefaultProjector prj,
                   Navigator nav,
