void	drawTile (StelPainter *painter, Vec3f color)

const ToastSurvey *	getSurvey () const
	Return the survey the tile belongs to.

const ToastGrid *	getGrid () const
	Return the toast grid used by the tile.

bool	isVisible (const SphericalCap &viewportShape, int maxVisibleLevel) const
	Return whether the tile should be drawn.

bool	isCovered (const SphericalCap &viewportShape) const
	return whether the tile is covered by its children tiles This is used to avoid drawing tiles that will be covered anyway

void	prepareDraw (Vec3f color)
	prepare arrays. color is set for a global brightness scaling. With atmosphere on, this will also set extinction effects.

Detailed Description

The tiles are stored in a tree structure
