Blender 3D︰從入門到精通/3D視圖窗口

跳至導覽 跳至搜尋

3D 視圖 窗口在Blender中用於顯示3D場景. 你將會有很多工作在這些窗口中, 因此你需要學習(so you will need to learn your way around).

3D視圖顯示的內容僅僅是和最終場景近似approximation. 整體上幾何體都是正確的, 但材質(materials),紋理(Textures),燈光(lighting)等沒有精確顯示, 因為那樣需要消耗很多時間, 而且3D視圖窗口設計用於快速響應你的交互操作。另外,還有其他視圖選項(如wireframe、隱藏等),這樣可以更容易地查看正在處理的模型的哪些部分,這對最終的渲染沒有影響。你也可以隨時改變你的視點(這在你的模型/場景中是很重要的),而渲染的視點是由攝像機的位置控制的( Plus there are additional view options (like wireframe, hiding etc) that make it easier to see what parts of the model you’re working on, that have no effect on the final render. Also you can change your viewpoint at any time (which will be essential while working on your model/scene), while the viewpoint of the render is controlled by the camera position.)

視窗及其內容(The Viewport and its Content)[編輯]



  1. 啟動Blender。
  2. 於是這樣我們都在看同樣的場景(就是面前啟動的Blender),(下面說的是怎樣使界面回到出廠設置) 加載 出廠設置,點擊 File → Load Factory Settings
  1. 確認 清除所有(Erase All) 通過鼠標左鍵  LMB  (or  Enter ).
  2. 如果鍵盤上的NumLock指示燈沒有亮,按下 NumLock  這樣,小鍵盤就能正常工作了。
  • 在 Blender 2.67a 中, 恢復出廠設置 目錄是 "加載默認文件和用戶首選項。" 所以它不顯示 清除所有(Erase All) 的信息。

(如果你不確定  LMB  是什麼意思, 請複習 the Keystroke, Button, and Menu Notation module.)章節的內容(儘管我已經標了出來)。


在這裏,視窗viewport就是被 紅色 圈起來的地方,把注意力集中在它上面。




1. 一個有橙色邊緣的灰色立方體。

  • 這就是

默認的多維數據庫 default cube , 你的第一個Blender 對象!

2. 三個大箭頭,一個紅的,一個綠的,一個藍的,它們的尾巴組成了一個白色的圓圈

  • 這不是對象(您的模型/場景的一部分),而是處理對象的Blender用戶界面的一部分。這是操縱器manipulator, 也被稱為3D變換組件 3D transform widget.
  • 箭頭表示正確選擇的 X, YZ 軸的方向, 這是一個變向transform orientation 坐標系。它默認為全局坐標系 global coordinate system.
  • 圓圈表示所選對象(即立方體)的中心。
  • 如果你不知道什麼是「全局坐標系」,請複習 the module on Coordinate Spaces in Blender.

3. A red-and-white striped circle with black cross-hairs

  • This is not an object. It is the 3D Cursor, which indicates where newly-created objects will appear in the scene.
  • The cursor is similar to the insertion point in a text editor, which indicates where newly-typed text will appear in a document.
In the Lower Left Corner


  • This is not an object. It is the mini axis, and its orientation matches that of the global coordinate system, with the usual conventions: red for X, green for Y and blue for Z. Think of it as a little compass, reminding you which way is left/right, front/back and up/down.

5. The notation "(1) Cube"

This is not an object. It is object info, indicating that:
  • You're viewing the first frame of an animation.
  • The current or most recently selected object is named "Cube".
In the Upper Left Corner

6. The notation 「User Persp」

This is not an object. This is telling you something about the view being displayed by the viewport. The first word will change if you select one of the perfect views or the camera view (see below), otherwise it just says 「User」, and the second word is 「Persp」 or 「Ortho」 to indicate whether this is a perspective or orthographic view.
To the Right of Center

7. A black round thing that resembles a sun-symbol

This represents a lamp, a light source for the scene. (It is an object.)

8. A pyramidal wireframe thing

This represents a camera, a viewpoint that can be used for rendering. (It, too, is an object.) The direction it is looking is out the base of the pyramid. The solid triangle attached to one side of the base is to remind you which way is up in the image that the camera takes.
On a small display, the camera might initially lie outside of the viewport and thus be invisible. In that case, zoom out by scrolling with  MMB  until it becomes visible.

9. A dark gray background, divided into squares by lighter lines. This is the grid floor, which you can (but don’t have to) use as a ground plane for positioning your models.

Each grid square is one blender unit (or BU) on a side. A BU can be whatever you wish: an inch, a centimetre, a mile, or a cubit. Blender lets you decide what the scale should be for your scene in the Scene tab of the Properties Panel.

10. Three mutually-perpendicular coloured lines associated with the grid floor: the red and green ones lying horizontally in the floor and the blue one running vertically. These are the global coordinate axes for orienting your scene: as usual, red is the X-axis, green the Y-axis, and blue the Z-axis.

  • In Blender 2.67a, you can't see the blue line for Z-axis here because you can see it in Front or Side view.


Blender has lots of modes, that is, settings that affect its behavior, and this is especially true of 3D View windows.

Sometimes it's not obvious what modes are active. This leads to mode errors where Blender will do something you didn't expect because you thought it was in one mode and it was actually in another.

In Blender, the function performed by a hotkey or mouse button can depend on:

  • what mode the user interface is in,
  • whether the keyboard is in NumLock mode,
  • which window is active,
  • the mode the active window is in,
  • which item or items are selected,
  • whether you've initiated a hotkey sequence.

It helps to recognize the common modes and get out of them.

物體模式(Object Mode)和編輯模式(Edit Mode)的對比[編輯]


    • 鼠標是一個白色箭頭(在 MacOS 中是黑色的)。
    •  RMB  被用來選擇屏幕上的物體。


  • 編輯模式(Edit Mode):用來編輯物體的形狀。
    • 此時鼠標是一個反相顯示的小叉叉。
    •  RMB  被用來選擇當前物體的頂點、面或邊緣。
    • 按下  Tab  進入或離開這個模式。
  • 雕塑模式(Sculpt Mode)

    • 此時鼠標又是一個細長橙環。



Viewport Options[編輯]

Solid vs. Wireframe[編輯]

By default, the 3D View window draws objects using the Solid drawtype, in which surfaces are opaque. To toggle between Solid and Wireframe drawtype (edges only, no faces) for a particular viewport:

  1. Activate the 3D View window.
  2. Press  Z .

Alternatively, you can choose these and other drawtypes from the "Draw type" menu in the 3D View window header.

Orthographic vs. Perspective[編輯]

By default, viewports draw orthographic views. To toggle a viewport between orthographic and perspective views:

  1. Activate the 3D View window.
  2. Press  Num5 .

(If you're unsure what the difference is, please review "Orthographic Views" 一節 and "Perspective Views" 一節.)

Note this perspective versus orthographic setting for the 3D viewport is completely separate from the similar setting in the camera properties; the former takes effect while you’re working on the model, the latter when you render.

So why have this separate setting for the 3D view? It’s because, regardless of what you want for the final render, certain aspects of modelling are easier in one view than another. If the final render will be using perspective, then naturally showing perspective in the 3D view gives you a better idea of how the final render will look. But perspective foreshortening can sometimes make it hard to ensure the model has the proper shape, which is why there is the option to flip to orthographic view if it helps.

Changing Your Viewpoint, Part One[編輯]

Each viewport has a viewpoint, which takes into account:

  • the location of the viewer in the 3D scene (There doesn't need to be an object at that location.)
  • the direction the viewer is looking
  • the magnification (or zoom factor) used

Changing your viewpoint allows you to navigate your way through a 3D scene.

We'll start with three very basic techniques:

  • Zooming
  • Orbiting/View Rotation
  • Perfect Views.

Additional techniques will be covered later in this module.


Blender offers several ways to zoom in and out:

  • Use  SCROLL 
  • Click and drag vertically with  Ctrl + MMB .
  • Use  Num+  and  NUM−  to zoom in and out in small increments.

Note the following limitations of Blender's zoom feature:

  • If the viewport is in orthographic mode, Blender zooms as if looking through a telescope. You can increase the magnification, but the viewpoint's location doesn't change. For this reason, you cannot zoom into or through objects in orthographic mode.
  • If the viewport is in perspective mode, Blender zooms to a point—namely the center of the viewport. The viewpoint can pass through objects, but it can't pass beyond this point, no matter what you do. Zooming only gets slower and slower and slower. If the center of the viewport is somewhere you don't expect, zooming may appear to be broken.

Orbiting and View Rotation[編輯]

Let's fly around in the default cube, viewing it from different angles. In this way you'll see that it really is a cube, centered on the origin, half above the X-Y plane and half below it.

  1. Activate the 3D View window by placing the mouse pointer inside it.
  2. Now you can:
    • Click and drag with  MMB  to orbit freely around the center of the view.
    • Use  Shift + Alt + SCROLL  to rotate the viewpoint vertically around the center of the view.
    • Use  Num2  and  Num8  to rotate the viewpoint vertically around the center of the view in 15-degree increments.
    • Use  Ctrl + Alt + SCROLL  to rotate the viewpoint around the Z axis.
    • Use  Num4  and  Num6  to rotate the viewpoint around the Z axis in 15-degree increments.

If this is all very confusing for you, don't worry! You'll learn as you get more experience.

When you are finished flying around the cube, you can restore the original view by reloading the factory settings with File → Load Factory Settings.

Perfect Views[編輯]

It's often useful to get a perfect view of a scene—in other words, to view it along one of the main axes, with the other two main axes oriented up-down and left-right.

Perfect View Hotkeys
Hotkey View Axis Pointing Right Axis Pointing Up
 Num7  "top" +X +Y
 Ctrl + Num7  "bottom" +X -Y
 Num1  "front" +X +Z
 Ctrl + Num1  "rear" -X +Z
 Num3  "right side" +Y +Z
 Ctrl + Num3  "left side" -Y +Z

The following screenshot shows all three perfect views plus camera perspective for the Suzanne primitive:

In fact, this layout of four viewports showing top, front and right views plus camera view is so commonly used that it has its own menu item (from the 「View」 menu, select 「Toggle Quad View」) and keyboard shortcut ( CTRL + ALT + Q ).

Positioning the 3D Cursor[編輯]

Positioning the 3D cursor is a very basic operation, yet one that many beginners find challenging. It touches on an issue common to all 3D graphics software: "How do you specify points in a 3D scene when we can only see two dimensions at a time?"

Basic Technique[編輯]

  1. Go into either Object Mode or Edit Mode.
  2. Move the mouse pointer to the desired position (in any viewport).
  3. Click  LMB .



Two Challenges[編輯]

Challenge #1. Using only tools presented thus far, try positioning the 3D cursor on the virtual camera.

Try it!

When you're done, check your work by orbiting the camera.

Perhaps you thought you were done when you clicked on the camera. But the moment you changed your viewpoint, you probably found that the 3D cursor was actually behind (or in front of) the camera.


  • Try positioning the cursor in two different perfect views.
  • Use orthographic views, not perspective ones.

Challenge #2. Using only tools presented thus far, try repositioning the 3D cursor at the origin (that is, at the center of the cube).

As before, check your work by orbiting the cube. Don't spend too much time on this.

More Ways to Position the Cursor[編輯]

Here's an easy way to position the cursor at the center of an object:

  1. Make sure Blender is in Object Mode, with the object selected.
  2. Move the mouse pointer to any 3D View window.
  3. Snap the cursor to the selected object using either:
    •  Shift + S  Cursor to Selected
    • Object → Snap → Cursor to Selected

Here's 2 easy ways to relocate the cursor to the scene's origin (0, 0, 0):

  1. Move the mouse pointer to any 3D View window.
  2. Press  Shift + C  to reset the cursor to the origin.
    • Note that this also changes the view location, meaning that when you zoom in, you won't zoom in to the scene origin.
  3. A better way is to click Object → Snap → Cursor to Center
    • You can also do this by  Shift + S Cursor to Center.

Changing Your Viewpoint, Part Two[編輯]

Now you'll learn some additional techniques for obtaining the view you want:

  • Panning
  • Centering
  • Jumping to the camera's viewpoint
  • Zooming in on a selected area


When you orbited the cube, the viewpoint's position and direction both changed at the same time. You also can shift the viewpoint up-down or left-right without changing its direction. (This is similar to the side-scrolling effect in the classic Mario and Sonic video games.)

This is called panning, and it's an important skill to master. Try it now:

  1. Activate a 3D View window by placing the mouse pointer inside it.
  2. Now you can:
    • Use  Shift + SCROLL  to pan up and down.
    • Use  Ctrl + Num2  and  Ctrl + Num8  to pan up and down in small increments.
    • Use  Ctrl + SCROLL  to pan left and right.
    • Use  Ctrl + Num4  and  Ctrl + Num6  to pan left and right in small increments.
    • Click and drag with  Shift + MMB  or  Shift + Alt + LMB  to pan freely in the viewplane.

You will likely find this to be a distraction in some cases. To move the viewpoint position back to the center, snap the cursor to the center, then click View → Align View → Center View to Cursor. You could also snap the cursor to the center then press  Ctrl + Num. .


When you zoom or rotate the view, you always zoom or rotate around the center of the view.

To center the view on an arbitrary point:

  1. Move the 3D cursor to the point of interest.
  2. Verify the cursor position from a second viewpoint.
  3. Press  Alt + Home  to center the view.

To center the view on an object in the scene:

  1. Make sure Blender is in Object Mode.
  2. Zoom out until the object is in the viewport.
  3. If any objects are selected, use  A  (or Select → Select/Deselect All) to deselect them.
  4. Select the object of interest by clicking  RMB  on it.
  5. Press  Num.  to center the view.

Jumping to the Camera's Viewpoint[編輯]

To see the scene as the virtual camera sees it, press  Num0 . Afterwards, you can rotate, pan, and zoom normally, but the virtual camera will not follow. To go back to your previous view, press  Num0  again. (In the latest versions of Blender, the virtual camera can be made to follow all the changes made in viewpoint while in camera view by checking the option "Lock Camera to View" on the Transform panel. Hit "N" on your keyboard to bring the transform panel. To disable this option you can uncheck that and get back to previous settings.)

Zooming into a Selected Area[編輯]

Suppose you want to get an extreme closeup of a particular area. Because there's no center mark on the viewport, you might have to pan and zoom several times to get the desired view.

The shortcut for zooming to an area is:

  1. Activate a 3D view window that contains the area of interest.
  2. Press  Shift + B . A crosshair appears in the viewport.
  3. Click and drag with  LMB  to draw a rectangle around the area of interest.
  4. When you release  LMB , the viewport will zoom in on the area you selected.

Fly Mode[編輯]

Another way of changing your viewpoint in the 3D view is with 「Fly Mode」. To activate this, press  SHIFT + F . Now you can use the mouse wheel to apply forward and backward 「thrust」: scroll up to accelerate forwards, scroll down to accelerate backwards, and leave the wheel alone to coast at constant speed. Also move the mouse (without pressing any buttons) to alter your orientation, up, down, left or right (the velocity vector will stay parallel to your forward/backward axis).

When you have reached the position and orientation you want, press  LMB  or  ENTER  to exit Fly Mode and stay there, or  RMB  or  ESC  to exit Fly Mode and be teleported immediately back to your original position and orientation.

Visibility Layers[編輯]

Every object in the scene is assigned to one of 20 visibility layers.

Visibility layers have many uses:

  • You can put scenery, characters, particles, and lamps in different layers, to help organize your scene.
  • By changing which layers are visible, you can simplify your view of the scene and work with only one or two layers at a time.
  • When rendering, only visible layers are included. You can use this to render your scene layer by layer, checking each layer separately.
  • You can configure lamps to illuminate only objects in the same layer.
Left: Viewing layer 1 only.
Right: Viewing all 20 layers.

In Object Mode, you can tell which layers are visible by looking at the twenty small boxes located in the 3D View header between the Transform Orientation menu and the "Lock" button. The top row of boxes represents layers 1 through 10, with 1 being the leftmost and 10 being the rightmost. Similarly, the bottom row of boxes represents layers 11 through 20.


  • To view just one of layers 1 .. 9, press  1KEY  ..  9KEY .
  • To view just layer 10, press  0Key .
  • To view just one of layers 11 .. 19, press  ALT + 1KEY  ..  ALT + 9KEY 
  • To view just layer 20, press  ALT + 0KEY .
  • To toggle the visibility of one of layers 1 .. 9 without affecting the visibility of the other layers, press  SHIFT + 1KEY  ..  SHIFT + 9KEY .
  • To toggle the visibility of layer 10 without affecting the visibility of the other layers, press  SHIFT + 0KEY .
  • To toggle the visibility of one of layers 11 .. 19 without affecting the visibility of the other layers, press  ALT + SHIFT + 1KEY  ..  ALT + SHIFT + 9KEY .
  • To toggle the visibility of layer 20 without affecting the visibility of the other layers, press  ALT + SHIFT + 0KEY .
  • To make all layers visible at once, press  ~ . Press  ~  again to return to your previous layer visibility setting.

Holding down  Shift  while selecting a layer (by keyboard or mouse) will, instead of making only that layer visible, toggle the visibility. In this way, you can select combinations or to hide particular layers.

The key to press to select all layers at once differs by keyboard layout. It is:

  •  ¬'  (the key under Esc) on UK keyboards,
  •  `~  on US ones,
  •  ö  on German, Swedish and Finnish ones,
  •  æ  on Danish ones,
  •  ù  on AZERTY ones,
  •  ø  on Norwegian ones,
  •  Ñ  on Spanish ones,
  •  "  on Brazilian Portuguese ones, and
  •  ò  on Italian ones.

After pressing the aforementioned key, holding down  Shift  while pressing it again will restore the visibility settings you had before you made all layers visible.

When only one layer is selected, new objects are automatically assigned to that layer. When two or more layers are visible, new objects are assigned to the layer that became visible most recently.

Count Your Polys[編輯]

If you want to count the polygons in your scene, this data is available in the Info Header.

As you can see in the above image, this scene has 507 vertices and 500 faces (polygons).
