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?

It is not necessary to display data in a graph if the linear transformation, a line segment, maps the window to the port preserving relative positions of the two dimensional view. The real world object is a transformedinto relative position points to the viewing volume.

Computer graphics begins then with linear transformations called clipping.

Explanation:

When surfing the internet using your mouse through tablets and mobile phones, the wizard´s default provided viewport varies as it is a polygon or the visible window mapped in computer graphics for a user redered by device-specific coordinates, position and orientation.

You can add multiple viewpoints as it is an HTML meta tag, @ rule in CSS. Styles and other features can be set when designing websites so you can provide the site to be shown in different devices.
