2-d Transformations

Translation

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).
