////////////////////////////////////////////////////////////
/// \class sf::Vector3
/// \ingroup system
///
/// sf::Vector3 is a simple class that defines a mathematical
/// vector with three coordinates (x, y and z). It can be used to
/// represent anything that has three dimensions: a size, a point,
/// a velocity, etc.
///
/// The template parameter T is the type of the coordinates. It
/// can be any type that supports arithmetic operations (+, -, /, *)
/// and comparisons (==, !=), for example int or float.
///
/// You generally don't have to care about the templated form (sf::Vector3<T>),
/// the most common specializations have special typedefs:
/// \li sf::Vector3<float> is sf::Vector3f
/// \li sf::Vector3<int> is sf::Vector3i
///
/// The sf::Vector3 class has a small and simple interface, its x and y members
/// can be accessed directly (there are no accessors like setX(), getX()) and it
/// contains no mathematical function like dot product, cross product, length, etc.
///
/// Usage example:
/// \code
/// sf::Vector3f v1(16.5f, 24.f, -8.2f);
/// v1.x = 18.2f;
/// float y = v1.y;
/// float z = v1.z;
///
/// sf::Vector3f v2 = v1 * 5.f;
/// sf::Vector3f v3;
/// v3 = v1 + v2;
///
/// bool different = (v2 != v3);
/// \endcode
///
/// Note: for 2-dimensional vectors, see sf::Vector2.
