Detailed Description

Convenience class that can be used to compute the TOAST grid points.

The ToastGrid class allows to compute the vertex arrays associated with TOAST tiles. Each method refers to a tile by its level and x and y coordinates.

QVector<Vec3d> ToastGrid::getPolygon	(	int	level,
		int	x,
		int	y
	)		const

Returns the polygon contouring a given tile.

Parameters

level	the TOAST level of the tile.
x	the x coordinate of the tile.
y	the y coordinate of the tile.

QVector<Vec2f> ToastGrid::getTextureArray	(	int	level,
		int	x,
		int	y,
		int	resolution
	)		const

Get the texture array for a given tile.

The position are stored in a grid

Parameters

level	the TOAST level of the tile.
x	the x coordinate of the tile.
y	the y coordinate of the tile.
resolution	the resolution of the returned array. TODO: UNITS?

QVector<unsigned short> ToastGrid::getTrianglesIndex	(	int	level,
		int	x,
		int	y,
		int	resolution
	)		const

Get the index of the vertex from getVertexArray sorted as a list of triangles.

Parameters

level	the TOAST level of the tile.
x	the x coordinate of the tile.
y	the y coordinate of the tile.
resolution	the resolution of the returned array. TODO: UNITS?

QVector<Vec3d> ToastGrid::getVertexArray	(	int	level,
		int	x,
		int	y,
		int	resolution
	)		const

Get the vertex array for a given tile.

The position are stored in a grid.

Parameters

level	the TOAST level of the tile.
x	the x coordinate of the tile.
y	the y coordinate of the tile.
resolution	the resolution of the returned array. TODO: UNITS?
