/// A vertex is an improved point. It has a position and other
|
|
/// extra attributes that will be used for drawing: in SFML,
|
|
/// vertices also have a color and a pair of texture coordinates.
|
|
///
|
|
/// The vertex is the building block of drawing. Everything which
|
|
/// is visible on screen is made of vertices. They are grouped
|
|
/// as 2D primitives (triangles, quads, ...), and these primitives
|
|
/// are grouped to create even more complex 2D entities such as
|
|
/// sprites, texts, etc.
|
|
///
|
|
/// If you use the graphical entities of SFML (sprite, text, shape)
|
|
/// you won't have to deal with vertices directly. But if you want
|
|
/// to define your own 2D entities, such as tiled maps or particle
|
|
/// systems, using vertices will allow you to get maximum performances.
|
|
///
|
|
/// Example:
|
|
/// \code
|
|
/// // define a 100x100 square, red, with a 10x10 texture mapped on it
|
|
/// sf::Vertex vertices[] =
|
|
/// {
|
|
/// sf::Vertex(sf::Vector2f( 0, 0), sf::Color::Red, sf::Vector2f( 0, 0)),
|
|
/// sf::Vertex(sf::Vector2f( 0, 100), sf::Color::Red, sf::Vector2f( 0, 10)),
|
|
/// sf::Vertex(sf::Vector2f(100, 100), sf::Color::Red, sf::Vector2f(10, 10)),
|
|
/// sf::Vertex(sf::Vector2f(100, 0), sf::Color::Red, sf::Vector2f(10, 0))
|
|
/// };
|
|
///
|
|
/// // draw it
|
|
/// window.draw(vertices, 4, sf::Quads);
|
|
/// \endcode
|
|
///
|
|
/// Note: although texture coordinates are supposed to be an integer
|
|
/// amount of pixels, their type is float because of some buggy graphics
|
|
/// drivers that are not able to process integer coordinates correctly.
