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 ( x = 0)

Sets all components of the vector to the same value

◆ Vector4() [2/3]

Vector4::Vector4 ( const T *  )
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)

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.
