Detailed Description

General purpose double pair, uses include representation of texture coordinates.

No support yet added for double * Vec2d - is it necessary? Need to define a non-member non-friend operator* etc. BTW: Vec2d * double is okay

Member Typedef Documentation

value_type

typedef double osg::Vec2d::value_type

Data type of vector components.

Member Enumeration Documentation

anonymous enum

anonymous enum

Number of vector components.

Member Function Documentation

isNaN()

bool osg::Vec2d::isNaN ( ) const

inline

Returns true if at least one component has value NaN.

length()

value_type osg::Vec2d::length ( ) const

inline

Length of the vector = sqrt( vec .

vec )

length2()

value_type osg::Vec2d::length2 ( void  ) const

inline

Length squared of the vector = vec .

vec

normalize()

value_type osg::Vec2d::normalize ( )

inline

Normalize the vector so that it has length unity.

Returns the previous length of the vector.

operator*() [1/2]

value_type osg::Vec2d::operator* ( const Vec2d &  rhs ) const

inline

Dot product.

operator*() [2/2]

const Vec2d osg::Vec2d::operator* ( value_type  rhs ) const

inline

Multiply by scalar.

operator*=()

Vec2d& osg::Vec2d::operator*= ( value_type  rhs )

inline

Unary multiply by scalar.

operator+()

const Vec2d osg::Vec2d::operator+ ( const Vec2d &  rhs ) const

inline

Binary vector add.

operator+=()

Vec2d& osg::Vec2d::operator+= ( const Vec2d &  rhs )

inline

Unary vector add.

Slightly more efficient because no temporary intermediate object.

operator-() [1/2]

const Vec2d osg::Vec2d::operator- ( const Vec2d &  rhs ) const

inline

Binary vector subtract.

operator-() [2/2]

const Vec2d osg::Vec2d::operator- ( ) const

inline

Negation operator.

Returns the negative of the Vec2d.

operator-=()

Vec2d& osg::Vec2d::operator-= ( const Vec2d &  rhs )

inline

Unary vector subtract.

operator/()

const Vec2d osg::Vec2d::operator/ ( value_type  rhs ) const

inline

Divide by scalar.

operator/=()

Vec2d& osg::Vec2d::operator/= ( value_type  rhs )

inline

Unary divide by scalar.

valid()

bool osg::Vec2d::valid ( ) const

inline

Returns true if all components have values that are not NaN.
