Detailed Description

template<class T>
class Vector3< T >

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]

template<class T >

Vector3< T >::Vector3 ( T  x = 0 )

inlineexplicit

The vector is not initialized!

Sets all components of the vector to the same value

Vector3() [2/2]

template<class T >

Vector3< T >::Vector3 ( const T *  x )

inlineexplicit

Explicit conversion constructor from an array (copies values)

Warning

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

Member Function Documentation

toStr()

template<class T >

QString Vector3< T >::toStr

(

)

const

Compact comma-separated string without brackets and spaces.

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