Inheritance diagram for random_racer::TerrainLoader:


Public Member Functions
	TerrainLoader (VRS::SO< VRS::SceneThing > thing, double boxSize, double viewSize, const VRS::Vector &initialPosition=VRS::Vector())
	Ctor, creates a new TerrainLoader with its worker thread.
virtual	~TerrainLoader ()
	Dtor, also stops the worker thread (by waiting).
double	boxSize ()
	Returns the current box size.
double	viewSize ()
	Returns the current view size.
virtual void	replaceTerrain (const VRS::Vector &position, const VRS::Vector &center)=0
	A pure-virtual method, usually called from LoaderGlue when a collision with a ReloadPlane happend.
Static Public Member Functions
template<class T>
static unsigned int	nearestIndex (double x, double y, T *cache, unsigned int size, bool debug=false)
	This method tells you which cached terrains index is the nearest for a given position.
Protected Attributes
VRS::Vector	m_position
	The current position of the car, to that the worker thread knows for where he should calculate things.
double	m_boxSize
	See TerrainLoader().
double	m_viewSize
	See TerrainLoader().
VRS::SO< VRS::SceneThing >	m_thing
	The SceneThing on which the specific TerrainLoader operates.

Detailed Description

The base class for the 2 TerrainLoader implementations VRSTerrainLoader and ODETerrainLoader.

Definition at line 26 of file TerrainLoader.h.

random_racer::TerrainLoader::TerrainLoader	(	VRS::SO< VRS::SceneThing >	thing,
		double	boxSize,
		double	viewSize,
		const VRS::Vector &	initialPosition = `VRS::Vector()`
	)

Ctor, creates a new TerrainLoader with its worker thread.

Parameters:

	thing	The SceneThing which this loader manages, the semantics are a bit different for ODE and VRS, see the specific Ctors for more info.
	boxSize	The dimensions of the box which says when to reload a new part of the terrain.
	viewSize	The dimenstions of the really visible terrain (should be more than boxSize).
	initialPosition	Where the initial position of the car or whatever is to fill the cache with some terrains in the ctor.

random_racer::TerrainLoader::~TerrainLoader ( ) [virtual]

Dtor, also stops the worker thread (by waiting).

double random_racer::TerrainLoader::boxSize ( ) [inline]

Returns the current box size.

double random_racer::TerrainLoader::viewSize ( ) [inline]

virtual void random_racer::TerrainLoader::replaceTerrain	(	const VRS::Vector &	position,
		const VRS::Vector &	center
	)			`[pure virtual]`

A pure-virtual method, usually called from LoaderGlue when a collision with a ReloadPlane happend.

Parameters:

	position	The new position of the car in our absolute world
	center	The center of the new collision box so we can calculate good new terrains.

template<class T>

static unsigned int random_racer::TerrainLoader::nearestIndex	(	double	x,
		double	y,
		T *	cache,
		unsigned int	size,
		bool	debug = `false`
	)			`[inline, static]`

This method tells you which cached terrains index is the nearest for a given position.

Parameters:

	x	The x coordinates of your position I talked about.
	y	Well, I hope you can guess this. :>
	cache	A templated type which acts as the cache in wich we search.
	size	How much items there are in the cache.
