Components

Vectors are usually made up of one to four components, named x, y, z, and w. Each component also has aliases for usage in colors rgba, and texture coordinates stpq. Accessing a component outside the vector will cause an error at compile time, for example:

vec2 pos;
float height;
pos.x;      // is legal
pos.z;      // is illegal
height.x;   // is legal in glsl, but illegal in c++
height.y;   // is illegal

Components can also be accessed with indices using the array access operator vector::operator[](size_t).

Swizzling

The fennec Vectors allows for the "swizzling" of vectors. Each component in the vector can be used in any combination, with up to 4 components, to create another vector. For example,

let \(V = (0, 1, 2)\) then \(V.xy = (0, 1)\) and \(V.zy = (2, 1)\)
