WebThe following shows the result of a affine transformation applied to a torus. A torus is described by a degree four polynomial. The red surface is still of degree four; but, its shape is changed by an affine transformation. Note that the matrix form of an affine transformation is a 4-by-4 matrix with the fourth row 0, 0, 0 and 1. Web25 jul. 2016 · Apply an affine transformation. The given matrix and offset are used to find for each point in the output the corresponding coordinates in the input by an affine transformation. The value of the input at those coordinates is determined by spline interpolation of the requested order.
