Clipping in Computer Graphics

The process of extracting a portion of a database or identifying elements of a scene within a specified region is called clipping.
In the context of clipping, the visible portion refers to the part of an object that lies within the window or viewing area.
A line entirely outside the window in clipping is called a trivially rejected line.
In the natural world coordinate system, the position of objects is defined using three-dimensional coordinates (x, y, z).
The rectangular region in the world coordinate system used for showing some part of an object inside a specified window is called the view volume.
A viewport is a rectangular region in the device coordinate system where the image is actually displayed on the screen.
The purpose of a coordinate transformation in computer graphics is to convert world coordinates to device coordinates for display on the screen.
Clipping in computer graphics is the process of determining which parts of an object are visible within a given window or viewing area.
Clipping is used to determine which lines to display by eliminating lines that lie outside the window or viewing area, making the rendering process more efficient.
Applications of clipping in computer graphics include windowing, view volume, and rendering.
During the clipping process, objects and points outside the window are eliminated, reducing the amount of data to be processed.
Clipping helps in drawing operations by reducing the complexity of the scene, improving rendering efficiency, and enhancing overall graphics performance.
