Understanding the Scene Gizmo
In the Scene view, you have several options for working in the viewport as you create and refine your
scene. The two main options are to view the scene in perspective mode or an isometric mode.
1.
Double-click the Main Camera once again in the Hierarchy view to get back to
some scene objects.
2.
Using the right mouse button (or any of the alternative methods), rotate the
view and observe the Scene Gizmo (Figure 1-18 ).
Figure 1-18. The Scene Gizmo in the upper right corner of the Scene view
The Scene Gizmo indicates the cardinal direction of the global or world directions. Currently you are
seeing the view in a perspective view, Persp, but you can use the Scene Gizmo to change to an iso
view, Iso. An 'iso' or isometric view is a view often used in drafting to create a 3D view without the
vanishing point perspective of the human eye. Unlike perspective, where objects farther back in the
scene appear smaller, in Iso, their size relative to each other is always correct. When coupled with
the cardinal directions (front, back top, bottom, left and right), Iso will show a flat orthographic view
that can make positioning objects much more accurate. When rotated off of the side or top/bottom
views, the view becomes isometric. You can toggle the lable to return to a perspective view.
3.
Select the Y or top view arrow on the gizmo.
The scene is seen from the top (Figure 1-19 ), but it's still the perspective view, as indicated by the
wedge-shaped icon next to the Top label, just below the gizmo.
