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

Here is the caller graph for this function:

osg::Vec2d::Vec2d ( value_type  x, value_type  y  )

inline

Definition at line 43 of file Vec2d.h.

Here is the call graph for this function:

osg::Vec2d::Vec2d ( const Vec2f &  vec )

inline

Definition at line 45 of file Vec2d.h.

Member Function Documentation

bool osg::Vec2d::isNaN ( ) const

inline

Returns true if at least one component has value NaN.

Definition at line 78 of file Vec2d.h.

Here is the call graph for this function:

Here is the caller graph for this function:

value_type osg::Vec2d::length ( ) const

inline

Length of the vector = sqrt( vec . vec )

Definition at line 151 of file Vec2d.h.

Here is the caller graph for this function:

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

inline

Length squared of the vector = vec . vec

Definition at line 157 of file Vec2d.h.

value_type osg::Vec2d::normalize ( )

inline

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

Definition at line 165 of file Vec2d.h.
