Keys Area

钥匙区

All existing keys that have not been hidden by filters will be displayed in chronological order in the Keys
Area. In addition, F-Curves can be displayed by clicking on the small arrow next to each curve.

所有没有被过滤器隐藏的键将按时间顺序显示在键区域中。此外,f 曲线可以通过点击每个曲线旁边的小箭头来显示。

A key’s value can be changed manually, without having to go to the Attributes Manager, by double-clicking on a
real key (i.e. not a master key). A new key can be created via Ctrl/Cmd
+ click on a given track (doing the same on a master track will create a key on all child tracks as well).
Information about the key interpolation used can be found under Interpolation.

通过双击一个实际的键(即不是主键) ,可以手动更改键的值,而不必转到 Attributes Manager。通过 Ctrl/Cmd + 单击给定的音轨可以创建一个新的键(在主音轨上做同样的操作也会在所有子音轨上创建一个键)。关于使用的键插值的信息可以在插值下找到。


Selection And The Concept Behind Master Keys

选择和主密钥背后的概念

Items in the Timeline are ordered chronologically. Maybe you are wondering why keys are also assigned to parent
objects. These parent (master) keys, depicted as outlines, have themselves no key value and serve only as
handles and selection assistants. A master key will be created in the parent hierarchy (i.e. for objects,
tags, materials, etc.) for each key you create for a given track.

时间轴中的项目按时间顺序排列。也许你想知道为什么键也分配给父对象。这些父(主)键被描述为轮廓,它们本身没有键值,只起到句柄和选择助手的作用。主密钥将在父层次结构中为您为给定轨道创建的每个密钥(即对象、标记、材质等)创建。

When a master key is selected, all keys of child hierarchies located at the exact same time in the animation
will also be selected. When normal keys are selected, corresponding master keys higher up in the hierarchy
will also be selected, however without the respective master key’s corresponding real keys being automatically
selected (only those actually belonging to the interactive selection).

当主密钥被选中时,动画中位于同一时间的所有子层次结构的密钥也将被选中。当选择普通键时,也将选择层次结构中位于较高位置的相应主键,但不会自动选择相应主键的相应实键(只选择实际属于交互式选择的主键)。

Selecting master keys will automatically select all
child keys. Selecting individual keys automatically selects the corresponding master keys. The marked master
keys are colored differently when not all of their real keys are selected. 选择主密钥将自动选择所有子密钥。选择单个密钥会自动选择相应的主密钥。当不是所有的主键都被选中时,被标记的主键的颜色是不同的

Master keys are colored differently, depending on the selection of real keys made:

主钥匙的颜色不同,取决于真钥匙的选择:

  • Selected: All of a given master key’s real keys are selected. 选择: 所有给定的主钥匙的真正钥匙都被选择
  • Partially selected: Not all of a
    given master key’s real keys are selected. 部分选中: 并非所有给定主密钥的实际密钥都被选中
  • Deselected: None of a given master key’s real keys are
    selected. 取消选择: 没有选择给定主密钥的任何实键

Selecting a master key will always result in all child keys being selected that are located at the same time in
the animation.

选择主密钥总是会导致在动画中同时选择所有子密钥。

Keys can be selected interactively as follows:

键可以交互式地选择如下:

  • By clicking on individual keys. Simultaneously pressing the 点击单独的按键。同时按Shift 转移
    button will make a 按钮将使from to 从到 selection available: Select a key and 可用的选择: 选择一个键并Shift 转移 + click on a second key. All keys that lie between these two keys, both
    horizontally and vertically, will be selected. Keys within this selection can be deselected or (re)selected
    via + 点击第二个键。所有位于这两个键之间的键,无论是水平还是垂直,都将被选中。在这个选择的密钥可以取消选择或(重新选择)通过Ctrl/Cmd + click. 点击
  • Drag a selection box around the keys you
    want to select. By simultaneously pressing the Ctrl-key (after pressing the mouse button), keys can be from an
    existing selection. 在要选择的键周围拖动选择框。通过同时按下 Ctrl-key (在按下鼠标按钮之后) ,可以从现有的选择中选择键

All keys at a given time in the animation can be selected via
动画中在给定时间的所有键都可以通过Shift 转移 + ALT + click on the master key of an object, tag, material, etc.
Alternatively you can click on the Track’s + ALT + 点击对象、标签、材质等的主键。或者你也可以点击赛道Masterkey.

Selected keys’ properties are displayed in the Attributes Manager.

选定键的属性显示在属性管理器中。

So I’ve selected some keys. What now?

所以我选择了一些键。现在怎么办?

You can move all selected keys by:

你可以通过以下方式移动所有选定的键:

  • moving one of the selected keys. 移动一个选定的键
  • moving the Selection Range in the Timeline Ruler. 移动时间线标尺中的选择范围

You can scale (slow motion, cycle) the selected keys temporally by moving one of the Selection Range’s handles
in the Timeline Ruler.

您可以通过移动时间线标尺中选择范围的一个手柄来缩放(慢动作,循环)所选择的时间键。

Simultaneously pressing the Ctrl-key while executing one of the selection methods just described will copy the
selected keys. Press Shift + Ctrl/Cmd to copy keys from one track to another.

在执行刚才描述的选择方法时同时按 Ctrl-key 将复制选定的键。按 Shift + Ctrl/Cmd 将按键从一个音轨复制到另一个音轨。

A symbol next to the cursor will alert you to whether or not the selected keys can be copied to a desired
location.

光标旁边的一个符号将提醒您选定的键是否可以复制到所需的位置。

  • Cursor with small Copy icon: OK 光标带有小复制图标: OK
  • Prohibition sign: not possible 禁止标志: 不可能


F-Curve Mode

F 曲线模式


General: What are F-Curves?

将军: 什么是 f 曲线?

The F in F-Curves stands for function (Function
Curves). F-Curves represent the interpolation between keys. F-Curves are not linked to any form of unit and
can therefore be used in conjunction with any property that can be interpolated smoothly between keys.

F 曲线中的 f 代表函数(函数曲线)。F 曲线表示键之间的插值。曲线不连接到任何形式的单位,因此可以结合使用的任何财产,可以平滑插入键之间。

Several properties, such as animated options (e.g., the transition
from hard to soft shadows), cannot be interpolated, i.e., the transition will be abrupt. 一些属性,例如动画选项(例如从硬阴影到软阴影的过渡) ,不能插入,例如,过渡将是突然的

What role do all the different types of interpolation play in a simple animation?

在一个简单的动画中,所有不同类型的插值起什么作用?

Take a look at the F-Curves shown below.

看看下面的 f 曲线。

Linear interpolation (top) and Spline interpolation
(bottom) 线性插值(上)及样条插值(下)

The keys on both F-Curves are located at the same time in the animation and have the same position, i.e., the
initial and final values are the same. If these were Position keys, the start and end positions would be the
same.

两个 f 曲线上的键在动画中同时位于同一位置,也就是说,初始值和最终值是相同的。如果这些是位置键,开始位置和结束位置将是相同的。


Tip:
提示:

Keys representing the brightness of a given light source or any other object property could also have been used
in the example above.
表示给定光源亮度或任何其他物体属性的键也可以在上面的例子中使用

How each F-Curve affects the animation can best be seen by playing the animation.

每个 f 曲线如何影响动画可以最好地看到播放的动画。

Example 1: A position animation in which an object moves at a constant velocity between point A and point B.
The fact that the object’s velocity remains constant makes its movement look unrealistic. A realistic movement
always involves an acceleration phase and a deceleration phase.

例1: 物体以恒定速度在 a 点和 b 点之间移动的位置动画。物体的速度保持不变这一事实使其运动看起来不真实。一个真实的运动总是包括加速和减速两个阶段。

In contrast, example 2: A curve ascends rapidly, quickly reaches its crest and continues in a straight line
until it arrives at the second key. The movement is as follows, based on the properties at hand: The value
increases rapidly and slows as it reaches the last frame, at which point no more changes will occur to the
value.

相比之下,例2: 曲线快速上升,迅速达到峰值,并沿直线继续,直到到达第二个键。根据手头的属性,移动如下: 当到达最后一帧时,值迅速增加并减慢,此时不会再发生对值的更改。

The object will move rapidly at the beginning of the animation, quickly slow until it stops. This is what a
realistic movement would look like.

这个物体在动画开始的时候会快速移动,快速的慢速移动直到停止。这就是现实主义运动的样子。

F-Curves define the temporal interpolation between keys. The Timeline offers numerous functions that let you
easily create acceleration and slowing movements for your objects.

F 曲线定义了键之间的时间插值。时间轴提供了许多功能,让您轻松创建加速和减慢运动为您的对象。


How to Use F-Curves

如何使用 f 曲线

If no settings have been changed in the F-Curve menu, only the F-Curves
of selected tracks will be displayed in the Objects Area.

如果在 F-Curve 菜单中没有更改设置,那么在对象区域中只会显示选定轨道的 F-Curves。

F-Curves of locked tracks will not be displayed. 锁定轨道的 f 型曲线将不会显示

For the most part, key tangents are displayed for selected keys and can be moved or edited interactively to
change the tangents (several selected keys can be edited at once). The following keyboard shortcuts can be
used (also in conjunction with Mini F-Curves in Dope Sheet mode):

在大多数情况下,键切线显示为选定的键,可以移动或交互编辑以改变切线(可以同时编辑多个选定的键)。下面的键盘快捷键可以使用(也可以与 Dope Sheet 模式中的迷你 f 曲线结合使用) :

  • Shift: Edit individual tangents. Left and right tangents are broken and can be edited
    separately. 编辑单独的切线。左右切线被打破,可以单独编辑
  • Ctrl: Tangent ascension remains constant; only tangent length can be edited. 相切提升保持不变; 只有相切长度可以编辑
  • ALT:
    Tangent length remains constant; only tangent rotation can be edited. 切线长度保持不变; 只有切线旋转可以编辑

Keys can be selected by clicking on them or dragging a selection box around the keys you want to select. You
can switch between selection states by simultaneously pressing the Ctrl-key.

可以通过单击键或拖动要选择的键周围的选择框来选择键。您可以通过同时按 ctrl 键在选择状态之间切换。

Shift key without affecting their values or time.>

在不影响他们的值或时间的情况下移动键

Selected keys can be moved using the Shift key without affecting their
values or time (vertically or horizontally) when the vertical or horizontal guidelines are displayed (you can
still subsequently switch between them outside of the tolerance radius while pressing the RMB). This also
works in the Dope Sheet’s F-Curve mode.

当显示垂直或水平指引时,选定的按键可以使用 Shift 键移动,而不会影响它们的值或时间(垂直或水平)(按人民币时,你仍然可以在公差半径以外的位置切换)。这也适用于涂料表的 f 曲线模式。

A line will be displayed along which individual keys can be moved.

将显示一行,其中单个键可以移动。

An entire F-Curve can be selected by clicking on it (selects an individual F-Curve) or by dragging a selection
box (multiple selection). Simultaneously pressing Shift + Ctrl/Cmd when selecting will switch between selection states.

一个完整的 f 曲线可以通过点击它(选择一个单独的 f 曲线)或者通过拖动选择框(多选择)来选择。选择时同时按下 Shift + Ctrl/Cmd 将在选择状态之间切换。

Most options in the Functions menu can also be applied to selected
F-Curves (as long as you are not in Dope Sheet mode).

函数菜单中的大多数选项也可以应用于选定的 f 曲线(只要您不处于 Dope Sheet 模式)。

A key can be added to an F-Curve via Ctrl/Cmd + click. Double-clicking on
an existing key lets you change its value right then and there. Information about the key interpolation used
can be found under Interpolation

可以通过 Ctrl/Cmd + click 向 F-Curve 添加一个键。双击现有的键可以立即更改它的值。关于使用的键插值的信息可以在插值下找到
