Sutherland and cohen subdivision line clipping algorithm
this is one of the most oldest and popular method for line clipping algorithm developed by "Dan cohen" and "Ivan sutherland".
This algo uses a 4 digit code to indicate which of the nine region contain the n point of the line, the 4 digit codes are called Region codes or out codes. these codes identifies the location...

Clipping
The process of selecting and viewing the picture with different views is called windowing , and a process which divides each element of a picture into its visible and non- visible portion allowing the invisible portion to be discarded is called CLIPPING.
we can generate different views of a picture by applying the appropriate scaling and translations by during...
