Incomputer graphics,swizzles are a class of operations that transformvectors by rearranging components.^[1] Swizzles can also project from a vector of one dimensionality to a vector of another dimensionality, such as taking a three-dimensional vector and creating a two-dimensional or five-dimensional vector using components from the original vector.^[2] For example, ifA = {1,2,3,4}, where the components arex,y,z, andw respectively, one could computeB = A.wwxy, whereuponB would equal{4,4,1,2}. Additionally, one could create a two-dimensional vector withA.wx or a five-dimensional vector withA.xyzwx. Combining vectors and swizzling can be employed in various ways. This is common inGPGPU applications.^[3]

In terms oflinear algebra, this is equivalent to multiplying by a matrix whose rows arestandard basisvectors. If${\displaystyle A=(1,2,3,4{)}^T}$, then swizzling${\displaystyle A}$ as above looks like
