Detailed Description

General purpose float pair. Uses include representation of texture coordinates. No support yet added for float * Vec2f - is it necessary? Need to define a non-member non-friend operator* etc. BTW: Vec2f * float is okay

Here is the call graph for this function:

Member Function Documentation

bool osg::Vec2f::isNaN ( ) const

inline

Returns true if at least one component has value NaN.

Definition at line 76 of file Vec2f.h.

Here is the call graph for this function:

Here is the caller graph for this function:

value_type osg::Vec2f::length ( ) const

inline

Length of the vector = sqrt( vec . vec )

Definition at line 149 of file Vec2f.h.

Here is the caller graph for this function:

value_type osg::Vec2f::length2 ( void ) const

inline

Length squared of the vector = vec . vec

Definition at line 155 of file Vec2f.h.

value_type osg::Vec2f::normalize ( )

inline

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

Definition at line 163 of file Vec2f.h.
