std::ostream & operator<< (std::ostream &output, const Vec4d &vec)

Detailed Description

General purpose double quad. Uses include representation of color coordinates. No support yet added for double * Vec4d - is it necessary? Need to define a non-member non-friend operator* etc. Vec4d * double is okay

Member Function Documentation

unsigned long osg::Vec4d::asABGR (   )  const [inline]
 

unsigned long osg::Vec4d::asRGBA (   )  const [inline]
 

bool osg::Vec4d::isNaN (   )  const [inline]
 

value_type osg::Vec4d::length (   )  const [inline]
 

Length of the vector = sqrt( vec . vec )

value_type osg::Vec4d::length2 (   )  const [inline]
 

Length squared of the vector = vec . vec

value_type osg::Vec4d::normalize (   )  [inline]
 

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

Vec4d osg::Vec4d::operator * (  value_type  rhs  )  const [inline]
 

Multiply by scalar.

value_type osg::Vec4d::operator * (  const Vec4d &  rhs  )  const [inline]
 

Dot product.

Binary vector add.

Vec4d& osg::Vec4d::operator+= (  const Vec4d &  rhs  )  [inline]
 

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

const Vec4d osg::Vec4d::operator- (   )  const [inline]
 

Negation operator. Returns the negative of the Vec4d.
