There are cases where it's preferable to navigate with first person controls,
especially for large environments such as architectural models.
In these cases orbiting around the view center is limiting.
While zoom, pan and dolly can be used, it's inconvenient.
With walk/fly navigation you can navigate around the scene where view rotation is
performed from the cameras location.
In the Preferences editor
select the navigation method you want to use as default when invoking the View Navigation operator.
Alternatively you can call the individual methods from the View ‣ Navigation menu.
Common use cases for walk/fly include:
Điều Hướng (Navigation)
Đây có thể là một cách nhanh chóng để điều hướng một cảnh lớn.
Camera Placement
When activated from a camera view, this will move the camera too.
Recording Animation
Running from a camera with auto-keyframe and playing animation
will record the motion as you make it allowing you to record the walk-through.
Góc Nhìn (View) ‣ Điều Hướng (Navigation) ‣ Điều Hướng Đi Bộ (Walk Navigation)
On activation the mouse pointer will move at the center of the view,
and a cross marker will appear...
This navigation method behaves similar to the first person navigation system available in most 3D world games.
It works with a combination of keyboard arrow keys and mouse movement.
Decrease the acceleration in the direction of motion,
if there is no motion, start accelerating backward.
Alt
Precision (slow the momentum).
Ctrl
Disable rotation -- while held, the view rotation doesn't influence the flight direction.
This allows you to fly past an object, keeping it centered in the view,
even as you fly away from it.
