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

Member Typedef Documentation

typedef float osg::Vec4f::value_type

Data type of vector components.

Member Enumeration Documentation

anonymous enum

Number of vector components.

Enumerator
num_components 

Constructor & Destructor Documentation

osg::Vec4f::Vec4f ( )
inline

Constructor that sets all components of the vector to zero

osg::Vec4f::Vec4f ( value_type  x,
value_type  y,
value_type  z,
value_type  w 
)
inline
osg::Vec4f::Vec4f ( const Vec3f v3,

value_type osg::Vec4f::g ( ) const
inline
bool osg::Vec4f::isNaN ( ) const
inline

Returns true if at least one component has value NaN.

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.

bool osg::Vec4f::operator!= ( const Vec4f v) const
inline
value_type osg::Vec4f::operator* ( const Vec4f rhs) const
inline

Dot product.

Vec4f osg::Vec4f::operator* ( value_type  rhs) const
inline

Multiply by scalar.

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.

Vec4f osg::Vec4f::operator- ( const Vec4f rhs) const
inline

Binary vector subtract.

const Vec4f osg::Vec4f::operator- ( ) const
inline

Negation operator. Returns the negative of the Vec4f.
