Detailed Description

General purpose float triple.

Uses include representation of color coordinates. No support yet added for float * Vec2b - is it necessary? Need to define a non-member non-friend operator* etc. Vec2b * float is okay

Member Typedef Documentation

typedef signed char osg::Vec2b::value_type

Data type of vector components.

Member Enumeration Documentation

anonymous enum

Number of vector components.

Enumerator
num_components

Constructor & Destructor Documentation

osg::Vec2b::Vec2b ( )

inline

Constructor that sets all components of the vector to zero.

osg::Vec2b::Vec2b ( value_type  r, value_type  g  )

inline

bool osg::Vec2b::operator!= ( const Vec2b &  v ) const

inline

Vec2b osg::Vec2b::operator* ( float  rhs ) const

inline

Multiply by scalar.

Vec2b& osg::Vec2b::operator*= ( float  rhs )

inline

Unary multiply by scalar.
