Detailed Description

General purpose double triple for use as vertices, vectors and normals.

Provides general math operations from addition through to cross products. No support yet added for double * Vec3d - is it necessary? Need to define a non-member non-friend operator* etc. Vec3d * double is okay

Member Typedef Documentation

typedef double osg::Vec3d::value_type

Data type of vector components.

Member Enumeration Documentation

anonymous enum

Number of vector components.

Enumerator
num_components

Constructor & Destructor Documentation

osg::Vec3d::Vec3d ( )

inline

Constructor that sets all components of the vector to zero.

osg::Vec3d::Vec3d ( const Vec3f &  vec )

inline

osg::Vec3d::Vec3d ( value_type  x, value_type  y, value_type  z  )

inline

osg::Vec3d::Vec3d ( const Vec2d &  v2, value_type  zz  )

inline

Member Function Documentation

bool osg::Vec3d::isNaN ( ) const

inline

Returns true if at least one component has value NaN.

value_type osg::Vec3d::length ( ) const

inline

Length of the vector = sqrt( vec .

vec )

value_type osg::Vec3d::length2 ( ) const

inline

Length squared of the vector = vec .

vec

value_type osg::Vec3d::normalize ( )

inline

Normalize the vector so that it has length unity.

Returns the previous length of the vector. If the vector is zero length, it is left unchanged and zero is returned.

osg::Vec3d::operator Vec3f ( ) const

inline

bool osg::Vec3d::operator!= ( const Vec3d &  v ) const

inline

value_type osg::Vec3d::operator* ( const Vec3d &  rhs ) const

inline

Dot product.

const Vec3d osg::Vec3d::operator* ( value_type  rhs ) const

inline

Multiply by scalar.

Vec3d& osg::Vec3d::operator*= ( value_type  rhs )

inline

Unary multiply by scalar.

const Vec3d osg::Vec3d::operator+ ( const Vec3d &  rhs ) const

inline

Binary vector add.

Vec3d& osg::Vec3d::operator+= ( const Vec3d &  rhs )

inline

Unary vector add.

Slightly more efficient because no temporary intermediate object.

const Vec3d osg::Vec3d::operator- ( const Vec3d &  rhs ) const

inline

Binary vector subtract.

const Vec3d osg::Vec3d::operator- ( ) const

inline

Negation operator.

Returns the negative of the Vec3d.

Vec3d& osg::Vec3d::operator-= ( const Vec3d &  rhs )

inline

Unary vector subtract.

const Vec3d osg::Vec3d::operator/ ( value_type  rhs ) const

inline

Divide by scalar.

Vec3d& osg::Vec3d::operator/= ( value_type  rhs )

inline

Unary divide by scalar.

bool osg::Vec3d::operator< ( const Vec3d &  v ) const

inline

bool osg::Vec3d::operator== ( const Vec3d &  v ) const

inline

value_type& osg::Vec3d::operator[] ( int  i )

inline

value_type osg::Vec3d::operator[] ( int  i ) const

inline

const Vec3d osg::Vec3d::operator^ ( const Vec3d &  rhs ) const

inline

Cross product.

value_type* osg::Vec3d::ptr ( )

inline

const value_type* osg::Vec3d::ptr ( ) const

inline

void osg::Vec3d::set ( value_type  x, value_type  y, value_type  z  )

inline

void osg::Vec3d::set ( const Vec3d &  rhs )

inline

bool osg::Vec3d::valid ( ) const

inline

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

value_type& osg::Vec3d::x ( )

inline

value_type osg::Vec3d::x ( ) const

inline

value_type& osg::Vec3d::y ( )

inline

value_type osg::Vec3d::y ( ) const

inline

value_type& osg::Vec3d::z ( )

inline

value_type osg::Vec3d::z ( ) const

inline
