Detailed Description

Single precision 2F vector class.

Constructor & Destructor Documentation

VECTOR2F::VECTOR2F ( )

inline

Constructs a new VECTOR2F object. The member fields are not initialized by this function.

VECTOR2F::VECTOR2F ( const VECTOR2F &  copy )

inline

Copies the contents of copy into this vector.

Parameters

copy	the vector from which to copy values into this vector.

References assign().

VECTOR2F::VECTOR2F ( float  nx, float  ny  )

inline

Constructs a vector with the values nx, ny and nz.

Parameters

nx	The x value to apply to this vector.
ny	The y value to apply to this vector.

Member Function Documentation

VECTOR2F VECTOR2F::add ( const VECTOR2F &  var )

inline

Returns the result of adding the vector var to this vector.

Parameters

var	The right side of the vector add operation.

Returns

The result of the vector add operation.

References x, and y.

void VECTOR2F::assign ( const VECTOR2F &  copy )

inline

Assigns the contents of copy to the member fields in this object.

Parameters

copy	The vector from which to copy values from.

Referenced by VECTOR2F().

float VECTOR2F::length ( )

inline

Returns the length of this vector.

Returns

The length of this vector.

Referenced by normalize().

VECTOR2F VECTOR2F::mul ( const VECTOR2F &  var )

inline

Returns the result of multiplying each component of the vector var with the corresponding component from this vector.

Parameters

var	The right side of the vector multiply operation.

Returns

The result of the vector multiply operation.

References x, and y.

void VECTOR2F::normalize ( )

inline

Performs an in-place normalization of this vector. Note that unlike other vector operations, this is a mutable member function rather than one that returns the result. After this function completes, the result of the length() function on this vector should be roughly 1.0.

References length().

VECTOR2F VECTOR2F::scale ( const float  scalar )

inline

Returns the result of scaling each field in this vector by the value scalar.

Parameters

scalar

The value that each member in this vector will be scaled by.

Returns

The result of the scaling operation.

VECTOR2F VECTOR2F::sub ( const VECTOR2F &  var )

inline

Returns the result of subtracting the vector var from this vector.

Parameters

var	The right side of the vector subtract operation.

Returns

The result of the vector subtract operation.

References x, and y.
