Viewport is the program's main window. A loaded scene is showed in it, and here you can edit a scene or a part of it using any tool the program gives you.
By default, Viewport consists of five windows: one big and four smaller ones. You can adjust the sizes of these windows by dragging their borders with the mouse.
Each window can be maximized by pressing Space. Pressing Space again will return the window to its previous size.
A scene is viewed through a virtual camera that can be controlled freely
General Camera Controls
Camera can be controlled by holding the Alt key:
- Alt + LMB rotates the camera
- Alt + RMB zooms the camera in and out (this can also be done by holding Alt and rotating mouse wheel)
- Alt + middle mouse button pans the camera
You can also quickly rotate the camera between planes by moving mouse while holding Ctrl, Alt and LMB.
The Viewcube is located in the upper right corner of the Viewport window. It shows (what exactly?) and can be used to quickly switch between pre-defined views.
Clicking one of the cones switches camera to a corresponding orthogonal perspective, of which there are six: Front (red cone) and Back, Right (blue) and Left and Top (green) and Bottom.
Pressing Ctrl+Alt switches camera view to a nearest orthogonal projection
Clicking the cube itself switches projection modes between perspective and isometric.
The lock symbol prevents the camera from moving, thus setting it to a fixed angle.
If you need to view your scene from a pre-defined angle, this can be achieved by adding a Camera object to the scene. To do this, select Camera from the Objects menu.
After you created a new Camera, select it by clicking its name in the Outliner window at the right:
Note: an additional camera is only visible when it is selected
Additional cameras cannot be adjusted using general controls described above. The only way to change their positions and spatial orientation is by applying manipulators.
To see the scene through an additional camera, press the Align to Camera button in the Toolbar.
The buttons on this panel are used for setting camera behavior.
Track Object - if this button is enabled, camera will follow selected object
Track Selection - if this button is enabled, camera will follow a selected part of an object (a controller or a mesh)
The aforementioned Align to Camera button to align the current view to a currently selected camera
Center Camera - this button focuses camera on a currently selected object. The hot key for it is T.
