Detailed Description

Namespace with GLSL types.

The sf::Glsl namespace contains types that match their equivalents in GLSL, the OpenGL shading language. These types are exclusively used by the sf::Shader class.

Types that already exist in SFML, such as sf::Vector2<T> and sf::Vector3<T>, are reused as type aliases, so you can use the types in this namespace as well as the original ones. Others are newly defined, such as Glsl::Vec4 or Glsl::Mat3. Their actual type is an implementation detail and should not be used.

All vector types support a default constructor that initializes every component to zero, in addition to a constructor with one parameter for each component. The components are stored in member variables called x, y, z, and w.

All matrix types support a constructor with a float* parameter that points to a float array of the appropriate size (that is, 9 in a 3x3 matrix, 16 in a 4x4 matrix). Furthermore, they can be converted from sf::Transform objects.
