TRANSLATION
A translation is applied to an object by repositioning it along a straight line
path from one coordinate location to another. We translate a two-dimensional
point by adding translation distances,
tx and
ty, to the
original coordinate position (x,y) to move the point to a new position
(x',y')
The translation distance pair (tx, ty) is called translation vector or shift vector
Matrix representation of translation
This allows us to write the two-dimensional translation equations in the matrix form:
