Detailed Description

template<typename T>
class sf::Vector3< T >

Utility template class for manipulating 3-dimensional vectors.

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:

• sf::Vector3<float> is sf::Vector3f
• 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:

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);

Note: for 2-dimensional vectors, see sf::Vector2.

Constructor & Destructor Documentation

Vector3() [1/3]

template<typename T >

sf::Vector3< T >::Vector3

(

)

Default constructor.

Creates a Vector3(0, 0, 0).

Vector3() [2/3]

template<typename T >

sf::Vector3< T >::Vector3	(	T	X,
		T	Y,
		T	Z )

Construct the vector from its coordinates.

Parameters

X	X coordinate
Y	Y coordinate
Z	Z coordinate

Vector3() [3/3]

template<typename T >

template<typename U >

sf::Vector3< T >::Vector3 ( const Vector3< U > & vector )

explicit

Construct the vector from another type of vector.

This constructor doesn't replace the copy constructor, it's called only when U != T. A call to this constructor will fail to compile if U is not convertible to T.

Parameters

vector

Vector to convert
