Public Attributes

value_type _v [4]

Detailed Description

General purpose float quad. Uses include representation of color coordinates. No support yet added for float * Vec4f - is it necessary? Need to define a non-member non-friend operator* etc. Vec4f * float is okay

bool osg::Vec4f::isNaN  )  const [inline]
 

value_type osg::Vec4f::length  )  const [inline]
 

Length of the vector = sqrt( vec . vec )

value_type osg::Vec4f::length2  )  const [inline]
 

Length squared of the vector = vec . vec

value_type osg::Vec4f::normalize  )  [inline]
 

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

Vec4f osg::Vec4f::operator * value_type  rhs  )  const [inline]
 

Multiply by scalar.

value_type osg::Vec4f::operator * const Vec4f rhs  )  const [inline]
 

Dot product.

Vec4f& osg::Vec4f::operator *= value_type  rhs  )  [inline]
 

Unary multiply by scalar.

Vec4f osg::Vec4f::operator+ const Vec4f rhs  )  const [inline]
 

Binary vector add.

Vec4f& osg::Vec4f::operator+= const Vec4f rhs  )  [inline]
 

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

const Vec4f osg::Vec4f::operator-  )  const [inline]
