Lastly, let’s look at the four views portrayed in the majority of the screen. When you first open the program, it defaults to four views, with a top, side, and front view of your workspace displaying the wireframes of your objects, and a fourth perspective view displaying an angled, solid-surfaced view that lets you get a more realistic idea of the final results as seen by a camera. You can change your views to have anywhere from one to four windows, and change the windows to display from the top, left, right, front, back, bottom, perspective, or any camera that you have set up in the scene.
The views displayed here (starting at the top left and going clockwise) are the top, front, perspective, and left-side views.
Right-clicking on any viewport will bring up a list of more options to let you further customize the windows or edit the objects and their assigned modifiers.
