Detailed Description

A templatized 4d vector compatible with OpenGL. Use Vec4i for integer and Vec4d or Vec4f typedef for vectors of double and float respectively.

Constructor & Destructor Documentation

Vector4() [1/3]

Vector4::Vector4 ( T  x = 0 )

inlineexplicit

Sets all components of the vector to the same value

Vector4() [2/3]

Vector4::Vector4 ( const T *  )

inlineexplicit

Warning

Does not check array size, make sure it has at least 4 elements

Vector4() [3/3]

template<class T2 >

Vector4::Vector4 ( const Vector4< T2 > &  other )

inlineexplicit

Uses default primitive type conversion

Member Function Documentation

toStr()

QString Vector4::toStr

(

)

const

The result can be restored into a Vector4 by the Vector4(QString s) constructors.
