Source: WordNetAffine transformation in plane geometry A simple affine transformation on the real plane Effect of applying various 2D affine transformation matrices on a unit square. Source: Internet
An affine transformation is invertible if and only if is invertible. Source: Internet
If there is a fixed point, we can take that as the origin, and the affine transformation reduces to a linear transformation. Source: Internet
Drawing with Bézier paths Composite Bézier curves may also be used to draw an ellipse to sufficient accuracy, since any ellipse may be construed as an affine transformation of a circle. Source: Internet
If is a matrix, : is equivalent to the following : The above-mentioned augmented matrix is called affine transformation matrix, or projective transformation matrix (as it can also be used to perform projective transformations ). Source: Internet
If these conditions do not hold, the formula describes a more general affine transformation of the plane provided that the determinant of A is not zero. Source: Internet
