Detailed Description

A templatized 3d vector compatible with OpenGL. Use Vec3i for integer and Vec3d or Vec3f typedef for vectors of double and float respectively.

Constructor & Destructor Documentation

Vector3() [1/2]

Vector3::Vector3 ( T  x = 0 )

inlineexplicit

Sets all components of the vector to the same value

Vector3() [2/2]

Vector3::Vector3 ( const T *  )

inlineexplicit

Warning

Does not check array size, make sure it has at least 3 elements

Member Function Documentation

operator=()

Vector3< T > & Vector3::operator= ( const T *  a )

inline

Warning

Does not check array size, make sure it has at least 2 elements

toStr()

QString Vector3::toStr

(

)

const

The result can be restored into a Vector2 by the Vector3(QString s) constructors.
