std::ostream & operator<< (std::ostream &output, const Vec3f &vec)

Detailed Description

General purpose float triple for use as vertices, vectors and normals. Provides general math operations from addition through to cross products. No support yet added for float * Vec3f - is it necessary? Need to define a non-member non-friend operator* etc. Vec3f * float is okay

Member Function Documentation

bool osg::Vec3f::isNaN  )  const [inline]
 

value_type osg::Vec3f::length  )  const [inline]
 

Length of the vector = sqrt( vec . vec )

value_type osg::Vec3f::length2  )  const [inline]
 

Length squared of the vector = vec . vec

value_type osg::Vec3f::normalize  )  [inline]
 

Normalize the vector so that it has length unity. Returns the previous length of the vector.

const Vec3f osg::Vec3f::operator * value_type  rhs  )  const [inline]
 

Multiply by scalar.

value_type osg::Vec3f::operator * const Vec3f rhs  )  const [inline]
 

Dot product.

Vec3f& osg::Vec3f::operator *= value_type  rhs  )  [inline]
 

Unary multiply by scalar.

bool osg::Vec3f::operator!= const Vec3f v  )  const [inline]
 

const Vec3f osg::Vec3f::operator+ const Vec3f rhs  )  const [inline]
 

Binary vector add.

Vec3f& osg::Vec3f::operator+= const Vec3f rhs  )  [inline]
 

Unary vector add. Slightly more efficient because no temporary intermediate object.

const Vec3f osg::Vec3f::operator-  )  const [inline]
 

Negation operator. Returns the negative of the Vec3f.

const Vec3f osg::Vec3f::operator- const Vec3f rhs  )  const [inline]
 

Binary vector subtract.

Vec3f& osg::Vec3f::operator-= const Vec3f rhs  )  [inline]
 

Unary vector subtract.

const Vec3f osg::Vec3f::operator/ value_type  rhs  )  const [inline]
 

Divide by scalar.

Vec3f& osg::Vec3f::operator/= value_type  rhs  )  [inline]
 

Unary divide by scalar.

bool osg::Vec3f::operator< const Vec3f v  )  const [inline]
 

bool osg::Vec3f::operator== const Vec3f v  )  const [inline]
 

value_type osg::Vec3f::operator[] int  i  )  const [inline]
