Detailed Description

The Vector4 object is a four component mathematical vector of floats packed together with some functionality to perform basic vector math.

Constructor & Destructor Documentation

TurtleBrains::Math::Vector4::Vector4 ( const SkipInitialization & fastAndStupid )

inlineexplicit

Constructs a Vector4 object leaving the members uninitialized and must be initialized manually before the object is used.

Note: Should be used only if the consequences are understood, and even then only sparingly.

TurtleBrains::Math::Vector4::Vector4 ( void )

inline

Constructs a default Vector4 object with all components set to 0.0f.

TurtleBrains::Math::Vector4::Vector4	(	const float	valueX,
		const float	valueY,
		const float	valueZ,
		const float	valueW
	)

inline

Constructs a Vector4 object with each component initialized with the values provided.

Parameters

valueX	The value to initialize the x component as.
valueY	The value to initialize the y component as.
valueZ	The value to initialize the z component as.
valueW	The value to initialize the w component as.

TurtleBrains::Math::Vector4::Vector4	(	const Vector2 &	other,
		const float	valueZ,
		const float	valueW
	)

inlineexplicit

Constructs a Vector4 object by copying a Vector2 object and providing a value for the z and w components.

Parameters

other	The Vector2 object to initialize the x and y component values to.
valueZ	The value to initialize the z component as.
valueW	The value to initialize the w component as.

TurtleBrains::Math::Vector4::Vector4	(	const Vector3 &	other,
		const float	valueW
	)

inlineexplicit

Constructs a Vector4 object by copying a Vector3 object and providing a value for the w component.

Parameters

other	The Vector3 object to initialize the x, y and z component values to.
valueW	The value to initialize the w component as.

TurtleBrains::Math::Vector4::Vector4 ( const float * componentArray )

inlineexplicit

Constructs a Vector4 object with the supplied float array, which must contain at least 4 floats.

Parameters

componentArray Must have at least 4 floats, one for each component in the Vector4.

TurtleBrains::Math::Vector4::Vector4 ( const Vector4 & other )

inline

Constructs a Vector4 object by copying another Vector4 object, each component will be initialized to the value of the other components.

Parameters

other The Vector4 object to initialize component values to.

TurtleBrains::Math::Vector4::~Vector4 ( void )

inline

Nothing needs to happen to destroy a Vector4 object.

Member Function Documentation

TurtleBrains::Math::Vector4::operator const float * ( void ) const

inlineexplicit

Returns a float array of the Vector4 components.

TurtleBrains::Math::Vector4::operator float * ( void )

inlineexplicit

Returns a float array of the Vector4 components. If modified the internal components will also be modified as well.

bool TurtleBrains::Math::Vector4::operator!= ( const Vector4 & other ) const

inline

Inequality operator, returns the opposite of the equality operator, which compares each value in one Vector4 object to another using IsEqual to compare the floating point component values.

Vector4& TurtleBrains::Math::Vector4::operator= ( const Vector4 & other )

inline

Assignment operator, sets each component of the Vector4 object to the values of the other object.

Parameters

other The Vector4 object to set the components to.

bool TurtleBrains::Math::Vector4::operator== ( const Vector4 & other ) const

inline

Equality operator, compares each component of the Vector4 object to the values of another Vector4 returning true if all components are equal, or false if any of the components are not equal.

Parameters

other The Vector4 object to compare against.

Note: Because the components are floating point values tbMath::IsEqual is used to compare the components for equality using the default tolerance: kTolerance.

const float& TurtleBrains::Math::Vector4::operator[] ( const int index ) const

inline

Returns a reference to one of the Vector4 components by an index provided by the VectorComponent enum.

float& TurtleBrains::Math::Vector4::operator[] ( const int index )

inline

Returns a reference to one of the Vector4 components by an index provided by the VectorComponent enum. If the reference returned is modified, the internal components will also be modified as well.

static Vector4 TurtleBrains::Math::Vector4::Zero ( void )

inlinestatic

Creates and returns a Vector4 object representing 0.0f, 0.0f, 0.0f, 0.0f.
