In computer graphics, swizzling is the ability to compose vectors by arbitrarily rearranging and combining components of other vectors. For example, if A = {1,2,3,4}, where the components are x, y, z, and w respectively, you could compute B = A.wwxy, whereupon B would equal {4,4,1,2}. Additionally, combining two two-component vectors can create a four-component vector, or any combination of vectors and swizzling. This is common in GPGPU applications.

| - Swizzling (nebo též operace či operátor swizzle) označuje v počítačové grafice „přeskládání“ jednotlivých složek vektoru, přičemž složky se mohou opakovat nebo mohou být vynechány. Mějme například vektor A = {1, 2, 3, 4}, jehož složky jsou x, y, z a w v daném pořadí. Potom můžeme vypočíst vektor B = A.wwxy, přičemž výsledný vektor bude roven B = {4, 4, 1, 2}. Tato operace se často používá v jazycích pro psaní shaderů (například jazyky GLSL, HLSL nebo Cg). (cs)
- Nella computer grafica, lo swizzling è la ricombinazione delle componenti di un vettore. Dal punto di vista dell'algebra lineare, si ottiene moltiplicando il vettore per una matrice le cui righe siano vettori della base. Ad esempio, dato il vettore , le cui componenti sono rispettivamente , , e , lo swizzling assume il valore . . (it)

In terms of linear algebra, this is equivalent to multiplying by a matrix whose rows are standard basis vectors. If , then swizzling as above looks like (en)
