Detailed Description

Models a single meteor.

Control of the meteor rate is performed in the MeteorMgr class. Once created, a meteor object only lasts for some amount of time, and then "dies", after which, the update() member returns false.

Constructor & Destructor Documentation

Meteor::Meteor	(	const StelCore *	,
		float	v
	)

Create a Meteor object.

Parameters

v	the velocity of the meteor in km/s.

Member Function Documentation

static void Meteor::buildColorArrays ( const int  segments, const QList< colorPair >  colors, QList< Vec4f > &  lineColorArray, QList< Vec4f > &  trainColorArray  )

static

Determine color arrays of line and prism used to draw meteor train.

static void Meteor::calculateThickness ( const StelCore *  core, float &  thickness, float &  bolideSize  )

static

Calculates the train thickness and bolide size.

void Meteor::draw	(	const StelCore *	core,
		StelPainter &	sPainter
	)

Draws the meteor.

static void Meteor::drawBolide ( const StelCore *  core, StelPainter &  sPainter, const MeteorModel &  mm, const Mat4d &  viewMatrix, const float  bolideSize  )

static

Draws the meteor bolide. (useful to be reused in MeteorShowers plugin)

static void Meteor::drawTrain ( const StelCore *  core, StelPainter &  sPainter, const MeteorModel &  mm, const Mat4d &  viewMatrix, const float  thickness, const int  segments, QList< Vec4f >  lineColorArray, QList< Vec4f >  trainColorArray  )

static bool Meteor::initMeteorModel ( const StelCore *  core, const int  segments, const Mat4d  viewMatrix, MeteorModel &  mm  )

static

Builds Meteor Model.

Returns

true if alive, else false.

bool Meteor::update

(

double

deltaTime

)

Updates the position of the meteor, and expires it if necessary.

Returns

true of the meteor is still alive, else false.

static bool Meteor::updateMeteorModel ( double  deltaTime, double  speed, MeteorModel &  mm  )

static

Updates parameters of meteor model.

(useful to be reused in MeteorShowers plugin)

Returns

true of the meteor is still alive, else false.
