Question

the window coordinates, Xwmin = 20, Xwmax = 80, Ywmin = 40,
Ywmax 80 and viewport coordinates, Xvmin = 30, Xvmax = 60, Yvmin = 40, Yvmax = 60.
​

Answer 1

Answer:

Window to Viewport Transformation is the process of transforming a 2D world-coordinate objects to device coordinates. Objects inside the world or clipping window are mapped to the viewport which is the area on the screen where world coordinates are mapped to be displayed.

General Terms:

World coordinate – It is the Cartesian coordinate w.r.t which we define the diagram, like Xwmin, Xwmax, Ywmin, Ywmax

Device Coordinate –It is the screen coordinate where the objects is to be displayed, like Xvmin, Xvmax, Yvmin, Yvmax

Window –It is the area on world coordinate selected for display.

ViewPort –It is the area on device coordinate where graphics is to be displayed.
