Any point in the object co-ordinate system is replaced by in the world co-ordinate system. The set of equations governing this transformation is:
The visible effect on the point is as follows:
where a is the translation in the x-direction and b is the translation in the y-direction.
Another way to think of this transformation is as a shift of co-ordinate axes by an amount (-a,-b).
