    Study Notes

    Windowing and Viewport Transformation

    • The method of selecting and enlarging a portion of a drawing is called windowing.
    • The area chosen for display is called the viewport.
    • The area on the display device to which a window is mapped is also called the viewport.
    • The term used for an imaginary box that encloses the desired or interested area of an object in computer graphics is called a window.
    • An area in object space that encloses the object is referred to as a bounding box.
    • Normalization and Viewport Transformation are part of the Viewing Pipeline.
    • The purpose of windowing in computer graphics is to select and enlarge a portion of a drawing.
    • A viewport is a region on the display device where the graphical output is displayed.
    • The window is selected by defining an imaginary box that encloses the desired or interested area of an object.
    • The significance of selecting an imaginary box to enclose the desired area of an object in computer graphics is to enable the visualization of a specific area of interest.
    • Normalization and viewport transformation are transformations applied to the object's coordinates to map the window to the viewport.
