In computer graphics, swizzles are a class of operations that transform vectors by rearranging components.
[2] 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}.
Combining vectors and swizzling can be employed in various ways.
[3] In terms of linear algebra, this is equivalent to multiplying by a matrix whose rows are standard basis vectors.
