Window to Viewport Transformation is a crucial process in computer graphics that involves mapping 2D world-coordinate objects to device coordinates. This transformation ensures that objects within the world or clipping window are accurately displayed on the screen within the designated viewport.
Key Concepts
World Coordinate: The Cartesian coordinate system used to define the diagram, such as Xwmin, Xwmax, Ywmin, Ywmax.
Device Coordinate: The screen coordinate system where the objects are displayed, such as Xvmin, Xvmax, Yvmin, Yvmax.
Window: The area on the world coordinate selected for display.
Viewport: The area on the device coordinate where graphics are displayed.
Mathematical Calculation
The transformation involves calculating the corresponding point (xv, yv) on the viewport for a given point (xw, yw) on the window. The relative position of the object in the window and viewport remains the same. The formulas for the x and y coordinates are:

Window port and Viewport in Computer Graphics - Includehelp.com
See more on includehelp.comThe window port can be confused with the computer window but it isn't the same. The window port is the area chosen from the real world for display. This window port decides what portion of the real world should be captured and be displayed on the screen. The widow port can thus be defined as, "A world-coordi…Window to Viewport Co-ordinate Transformation
