There is one mode of zooming we haven't mentioned yet. It is the region zoom. The only difference is that it is available only in Orthographic views. You right click on any orthographic viewport (Front, Top etc) to make it active. When you look at the viewport tools, you can see the Region Zoom among the tools. Click to select it. Now click and drag inside any of the orthographic viewports to draw a rectangle. Dont draw a rectangle having the whole size of the viewport. Draw a small one. When you release the mouse button, you will notice that the region you have drawn zooms in to fit in the viewport in 3D Studio MAX ( 3ds max ).
Now left-click on the 'Perspective' viewport to make it active. Now you will notice that the Region Zoom tool has gone and another tool replaced it in the viewport tools section. It is the Field of View tool. Select it and Click-drag inside the perspective viewport. You will notice a kind of zooming. But its not exactly zooming. The Field of View (FOV) of the camera (perspective is a simple camera in 3D Studio MAX ( 3ds max )) is changing. It is a property of the camera lens that makes the view captured by it wider or narrower. We will discuss more about FOV when we learn cameras in later tutorials & lessons of 3D Studio MAX ( 3ds max ). For now, you just experiment with the tool and get a rough idea. ok?
