Điểm Nhìn (Viewpoint)

Blender uses a right-angled "Cartesian" coordinate system with the Z axis pointing upwards.

X axis

Trái / Phải (Left / Right)

Y axis

Front / Back

Z axis

Top / Bottom

You can select the viewing direction for a 3D Viewport with the View menu entries, Navigation Gizmo, or by pressing the hotkeys.

These operators change the view to be aligned with the specified global axes:

Đỉnh (Top)

Số 7 Bàn Số (Numpad7)

Đằng Trước (Front)

Số 1 Bàn Số (Numpad1)

Phải (Right)

Số 3 Bàn Số (Numpad3)

Holding Ctrl shows the other side of the same axis:

Đáy (Bottom)

Ctrl-Số 7 Bàn Số (Numpad7)

Đằng Sau/Quay Trở Lại (Back)

Ctrl-Số 1 Bàn Số (Numpad1)

Trái (Left)

Ctrl-Số 3 Bàn Số (Numpad3)

Holding Shift aligns the view relative to the active selection. So you can for example, view a rotated objects side, or align the view to the active face in mesh Edit Mode.

The view can also be aligned by holding Alt-MMB and moving the mouse towards the view to align to.
