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 ( 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.
