2-Dimensional Translation:
Translation is a simple straight line movement of the object
Figure
As illustrated in Figure coordinates (x1, y1) have been translated to the new coordinates
(x′, y′).
x′1 = x1 + Tx
y′1 = y1 + Ty
Likewise, for other points or any object such like a polygon, by adding up the translation distances (Tx, Ty) for each of endpoint of the object the required translation is achieved.
