WebThe effect of a transformation on a group of points defining a 2D polygon or 3D object varies from simple changes of location and orientation (without any change in shape or size), to uniform scale change (no change in shape), and, finally, to changes in shape and size of different degrees of non-linearity (Mikhail 1976). WebHelmert 2D. Also known as 4-parameter similarity transformation. The transformation process involves 3 steps: scaling, rotation and translations. The first two are defined by one parameter each and the translations include 2. At least two pairs of points are necessary.
