std::string LocalMap::coordStr	(	const int	x,
		const int	y
	)		[private]

void LocalMap::deleteBuffers

[private]

void LocalMap::getInteriorMapPosition	(	Ogre::Vector2	pos,
		float &	nX,
		float &	nY,
		int &	x,
		int &	y
	)

Get the interior map texture index and normalized position on this texture, given a world position (in ogre coordinates)

bool LocalMap::isPositionExplored	(	float	nX,
		float	nY,
		int	x,
		int	y,
		bool	interior
	)

Check if a given position is explored by the player (i.e. not obscured by fog of war)

void LocalMap::render	(	const float	x,
		const float	y,
		const float	zlow,
		const float	zhigh,
		const float	xw,
		const float	yw,
		const std::string &	texture
	)		[private]

void LocalMap::requestMap	(	MWWorld::CellStore *	cell,
		float	zMin,
		float	zMax
	)

Request the local map for an exterior cell.

Remarks:

It will either be loaded from a disk cache, or rendered if it is not already cached.

Parameters:

cell	exterior cell
zMin	min height of objects or terrain in cell
zMax	max height of objects or terrain in cell

void MWRender::LocalMap::requestMap	(	MWWorld::CellStore *	cell,
		Ogre::AxisAlignedBox	bounds
	)

Request the local map for an interior cell.

Remarks:

It will either be loaded from a disk cache, or rendered if it is not already cached.

Parameters:

cell	interior cell
bounds	bounding box of the cell

const Ogre::Vector2 LocalMap::rotatePoint	(	const Ogre::Vector2 &	p,
		const Ogre::Vector2 &	c,
		const float	angle
	)		[private]

void LocalMap::saveFogOfWar

(

MWWorld::CellStore *

cell

)

Save the fog of war for the current cell to disk.

Remarks:

This should be called before loading a new cell, as well as when the game is quit.

Parameters:

current

cell

void LocalMap::saveTexture	(	const std::string &	texname,
		const std::string &	filename
	)		[private]

void LocalMap::updatePlayer	(	const Ogre::Vector3 &	position,
		const Ogre::Quaternion &	orientation
	)

Set the position & direction of the player.

Remarks:

This is used to draw a "fog of war" effect to hide areas on the map the player has not discovered yet.

Parameters:

position	(OGRE coordinates)
camera	orientation (OGRE coordinates)
