I have mapped four rectangular point(R1->R4) to four quadrilateral points(Q1->Q4) to generate a perspective view. Now I have to translate quadrilateral in x and y direction while maintaing perspective view. How can I achieve this?

    $\begingroup$ The standard approach is to use a transformation $T$ that does the conversion form space to space. In this case Homogeneous coordinates could be used. The process is pretty well described here. Feel free to write a proper answer so that the question wont hang here forever. $\endgroup$ – joojaa May 19 '16 at 8:12
