Detailed Description

Implements all the virtual methods in ZoneArray.

Is only separate from ZoneArray because ZoneArray decides on the template parameter.

Template Parameters

Star	either Star1, Star2 or Star3, depending on the brightness of stars in this catalog.

Constructor & Destructor Documentation

template<class Star >

SpecialZoneArray< Star >::SpecialZoneArray	(	QFile *	file,
		bool	byte_swap,
		bool	use_mmap,
		int	level,
		int	mag_min,
		int	mag_range,
		int	mag_steps
	)

Handles loading of the meaty part of star catalogs.

Parameters

file	catalog to load from
byte_swap	whether to switch endianness of catalog data
use_mmap	whether or not to mmap the star catalog
level	level in StelGeodesicGrid
mag_min	lower bound of magnitudes
mag_range	range of magnitudes
mag_steps	number of steps used to describe values in range

template<class Star >

void SpecialZoneArray< Star >::draw	(	StelPainter *	sPainter,
		int	index,
		bool	isInsideViewport,
		const RCMag *	rcmag_table,
		int	limitMagIndex,
		StelCore *	core,
		int	maxMagStarName,
		float	names_brightness,
		const QVector< SphericalCap > &	boundingCaps,
		const bool	withAberration,
		const Vec3f	vel
	)		const

overrideprotectedvirtual

Draw stars and their names onto the viewport.

Parameters

sPainter	the painter to use
index	zone index to draw
isInsideViewport	whether the zone is inside the current viewport. If false, we need to test more to skip stars.
rcmag_table	table of magnitudes
limitMagIndex	index from rcmag_table at which stars are not visible anymore
core	core to use for drawing
maxMagStarName	magnitude limit of stars that display labels
names_brightness	brightness of labels
boundingCaps
withAberration	true if aberration to be applied
vel	velocity vector of observer planet
