先学：Prerequisites: 节点

学习目标LEARNING OBJECTIVES

学完你能在节点编辑器（Node Editor）里自如地平移缩放、把节点装进查看器，并把节点树整理得清清爽爽。

概念说明CONCEPTS

节点编辑器是 Fusion 页面下方搭建节点树的工作区——加节点、连管道、理布局都在这里，它是你在合成里待得最久的地方。

  • 连接重于位置：画面只由管道连接决定，节点怎么摆都行——但整齐的树，一周后你还看得懂。
  • 装进查看器看中间结果：选中节点按 1 进左查看器、按 2 进右查看器，随时抽查任何一环的画面。
  • 导航手势全局通用：中键拖动平移、Cmd+滚轮（Win: Ctrl+滚轮）缩放，在查看器和曲线编辑器里同样有效。
  • 大工程靠导航器：按 V 唤出 Navigator 缩略图，节点再多也不迷路。

操作步骤STEPS

  1. 按住鼠标中键在空白处拖动，平移整个节点树（触控板用 Cmd-Shift+左键拖）
  2. 按住 Cmd（Win: Ctrl）滚动滚轮，以指针为中心缩放节点树
  3. 选中一个节点按 1 装进左查看器，再选另一个按 2 装进右查看器，对比两环画面两个节点分别装进左右查看器对比
  4. 按 V 打开 Navigator 缩略图，点缩略图快速跳到节点树的任意位置
  5. 右键空白处选 Options > Orthogonal Pipes，再选 Line Up All Tools to Grid 整理全局Options 菜单中的走线与对齐选项

练习PRACTICE

  1. 把两个节点分别装进左右查看器，然后按 ` `` 键一键清空双查看器。
  2. 把节点树平移缩放到找不着北，再用 Navigator 缩略图跳回全局视图。

常见问题FAQ

触控板没有中键怎么平移？

按住 Cmd-Shift（Win: Ctrl-Shift）加左键拖动即可。不过在 Fusion 里，一只三键鼠标或数位板会舒服很多。

查看器里的画面怎么一键适配窗口？

点一下查看器按 Cmd-F（Win: Ctrl-F）；+ / - 逐级缩放，Cmd-1 直接回 100%。

节点摆乱了会影响最终画面吗？

不会，结果只看连接。但乱摆的树没人看得懂——用 Options 里的对齐工具花十秒整理一下。

Learning Objectives学习目标

After this card you can pan and zoom the Node Editor with confidence, load nodes into the viewers, and keep a node tree tidy.

Concepts概念说明

The Node Editor is the workspace at the bottom of the Fusion page where you build the node tree — adding nodes, wiring pipes, and arranging the layout all happen here; it's where you'll spend most of your compositing time.

  • Connections over position: the picture depends only on the pipes — nodes can sit anywhere. But a tidy tree stays readable a week later.
  • Load nodes into viewers: select a node and press 1 for the left viewer, 2 for the right — spot-check any stage of the flow anytime.
  • Navigation gestures travel: middle-drag to pan, Cmd+scroll to zoom (Ctrl+scroll on Windows) — the same moves work in viewers and the curve editors.
  • Big trees need the Navigator: press V for a miniature map of the whole tree, so you never get lost.

Steps操作步骤

  1. Hold the middle mouse button and drag on empty space to pan the tree (on a trackpad use Cmd-Shift + left-drag)
  2. Hold Cmd (Ctrl on Windows) and scroll to zoom around the pointer
  3. Select a node and press 1 for the left viewer, select another and press 2 for the right — compare the two stagesTwo nodes loaded into the left and right viewers
  4. Press V to open the Navigator miniature, then click it to jump anywhere in the tree
  5. Right-click empty space and choose Options > Orthogonal Pipes, then Line Up All Tools to Grid to tidy upPipe and alignment options in the Options menu

Practice练习

  1. Load two nodes into the left and right viewers, then press ` `` to clear both at once.
  2. Pan and zoom until you're lost in the tree, then use the Navigator to jump back to the big picture.

FAQ常见问题

No middle mouse button on my trackpad — how do I pan?

Hold Cmd-Shift (Ctrl-Shift on Windows) and left-drag. That said, a three-button mouse or a pen tablet makes Fusion much friendlier.

How do I fit the picture to the viewer in one keystroke?

Click the viewer and press Cmd-F (Ctrl-F on Windows); + / - zoom in steps, Cmd-1 jumps straight to 100%.

Does a messy layout hurt the final image?

No — only connections decide the result. But nobody can read a messy tree; spend ten seconds with the alignment tools under Options.
