LogoutThe main difference between window port and view port is that window port is a world coordinate area selected for displaying while view port is a device coordinate area that locates the scene on the device.
A portion of a picture that is to be displayed by a window is known as window port. The display area of the part selected or the form in which the selected part is viewed is known as view port.
Window port is the world coordinate area to display. A window is a graphical control element. It consists of a visual area containing some of the Graphical User Interface (GUI). Furthermore, there is a frame by a window decoration. Therefore, this window port is a window that defines a rectangular area in world coordinates.
Furthermore, it is possible to define the window size. It can be larger, smaller or the same size depending on whether to display all data or only a part of data.
A view port is a part of the computer screen. In other words, it is an area on a device to map the object. Therefore, it is the region according to the device coordinates. It is possible to describe the viewport by rendering device-specific coordinates. For example, it denotes the pixels of screen coordinates to render. Depending on the requirement, it is possible to display the entire display device or to display only a portion.
Furthermore, viewing transform or window to view port mapping is the process of mapping the part of the world coordinate scene to device coordinate sense. Likewise, it is possible to map the objects in the world coordinates to the view port.
Difference Between Window Port and View Port
Definition
Window port is the world coordinate area to display. In contrast, the view port is the device coordinate area to display. Thus, this is the main difference between window port and view port.
Basis
Moreover, window port is the region created according to the world coordinates while the view port is the region created according to the device coordinates.
Functionality
Window port helps to determine the section of the scene to be displayed, whereas the viewport helps to position the scene on the output device. This is another difference between window port and view port.
Conclusion
In brief, window to view port mapping or viewing transformation is the process of bringing the world coordinate screen to match the device coordinate screen. The main difference between window port and view port is that window port is a world coordinate area selected for displaying while view port is a device coordinate area that locates the scene on the device.
