Constructor & Destructor Documentation

HipsSurvey()

HipsSurvey::HipsSurvey	(	const QString &	url,
		double	releaseDate = 0.0
	)

Parameters

url	The location of the survey.
releaseDate	If known the UTC JD release date of the survey. Used for cache busting.

draw()

void HipsSurvey::draw	(	StelPainter *	sPainter,
		double	angle = 2.0 *M_PI,
		DrawCallback	callback = Q_NULLPTR
	)

Parameters

sPainter	the painter to use.
angle	total visible angle of the survey in radians. This is used to optimize the rendering of planet surveys. Should be set to 2 pi for sky surveys.
callback	if set this will be called for each visible tile, and the callback should do it rendering itself. If set to Q_NULLPTR, the function will draw the tiles using the default shader.
