Affine Transformations — Pan, Zoom, Skew.

In graphics, there is often a need to zoom, pan and skew a set of points. In this article we will take a look at one method to produce such a transformation — Affine Transformations An Affine Transformation is a transformation that preserves the collinearity of points and the ratio…
