Detailed Description

General purpose double pair, uses include representation of texture coordinates. No support yet added for double * Vec2d - is it necessary? Need to define a non-member non-friend operator* etc. BTW: Vec2d * double is okay

Member Function Documentation

isNaN()

bool osg::Vec2d::isNaN ( ) const

inline

Returns true if at least one component has value NaN.

References _v, and osg::isNaN().

Referenced by valid().

length()

value_type osg::Vec2d::length ( ) const

inline

Length of the vector = sqrt( vec . vec )

References _v.

Referenced by normalize().

length2()

value_type osg::Vec2d::length2 ( void ) const

inline

Length squared of the vector = vec . vec

References _v.

normalize()

value_type osg::Vec2d::normalize ( )

inline

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

References _v, and length().

operator Vec2f()

inline

References _v.

operator!=()

bool osg::Vec2d::operator!= ( const Vec2d & v ) const

inline
