;The Introduction and F-Curve Interpolation part of this page was originally written by [[User:Jaredr122|Jaredr122]] 2011.
;Then modified by a set of users.

= Animation Tools: Channels =

I am a bit lost how to write this.

== Funny Actions ==

;bpy.data.actions['CubeAction'].groups['Location'].channels[0].keyframe_points[2].interpolation='LINEAR'

;Action: An action holds a set of animation data for an object.
;Group: A group of channels, example, location, rotation.
;Channel: A property of an object that can be animated. These are what have FCurves. They are like Drivers.
;Keyframe: An FCurve control point.

;Channels

>>> bpy.data.objects['Cube'].animation_data.drivers[0]
bpy.data.objects['Cube']...FCurve

>>> bpy.data.actions['CubeAction'].groups['Location'].channels[0]
bpy.data.actions['CubeAction']...FCurve

== Channels ==

[[File:Doc_Animation_Driver_FCurve.PNG|frame|Graph Editor: Channel F-Curve.]]

Channels have an F-Curve which is used to animate objects.

Channels use time to control the values of properties.

Using a F-Curve, the channel reads the time frame and sets the value of the property.

So from this example, if the time frame is 2.0 the property will be 0.5.

.

== Introduction ==

;Keyframes are one of the main objects used for animation. Keyframes define a value of data at a specified frame.

[[File:Doc_Kia_Keyframes.PNG|frame|center|Keyframes.]]

;Quite obviously, something is "animated" when it changes over time. In Blender, animating an object means changing its properties over time, such as its X location, or the Red channel value of its material diffuse color, and so on.

Blender's fundamental unit of time is the "frame", which usually lasts just a fraction of a second, depending on the ''frame rate'' of the scene.

== F-Curve Interpolation ==

As animations are composed of incremental changes spanning multiple frames, usually these properties ARE NOT manually modified ''frame by frame'', because:
* it would take ages!
* it would be very difficult to get a smooth variation of the property.

This is why nearly all direct animation is done using '''interpolation'''.

The idea is simple: you define a few “control points”, called "'''keyframes'''", which are multiple frames apart.

[[File:Blender24-animation-interpolation-concept.png|thumb|200px|right|Example of interpolation]]

;Between these keyframes, the properties values are interpolated, allowing for a smooth transition between keyframes. Thus, the animators' workload is significantly reduced.

For example, if you have:
* a control point of value '''0''' at frame '''0''',
* another one of value '''10''' at frame '''25''',
* linear interpolation,
then, at frame '''5''' we get a value of '''2'''.

The same goes for all intermediate frames: with just two points, you get a smooth growth from '''0''' to '''10''' along the '''25 frames'''.
Obviously, if you’d like the frame '''15''' to have a value of '''9''', you’d have to add another control point (or keyframe)…

= Adding Keyframes =

;Here are some common ways to animate objects by adding keyframes.
;These methods can be used on different objects, like armature bones in pose mode.

== Insert Keyframe ==

[[File:Doc_kia_Cube00.PNG|frame|center|Add keyframe to Cube.]]

[[File:Doc_kia_Cube01.PNG|frame|Keyframes in the Timeline.]]

;In the Timeline Editor, move the green frame cursor to 0, by pressing or holding {{Shortcut|LMB}}.

;With a Mesh Object selected in Object Mode, and the frame set in the Timeline. In the 3D View Tools press the 'Insert Keyframe' button, or press {{Shortcut|I}} in the 3D View to bring up the 'Insert Keyframe Menu'.

;Select 'Location', this will record the location of the Mesh Object on the frame the Timeline cursor is set.

;Set the Timeline cursor to a different frame, move the Mesh Object, then insert another keyframe.

;The keyframes are displayed in yellow on the Timeline. Move the Timeline cursor to test the animation.

== Keying Sets ==

[[File:Doc_kia_Cube02.PNG|frame|Timeline Keying Sets.]]

;Keying Sets are a set of keyframes in one. They are made to record multiple properties at the same time. There are some built in keying sets, and also custom keying sets.

;Use the keying set menu in the Timeline editor, to select a keying set. Now when you insert a keyframe, blender will add keyframes for the selected keying set.

;See [[Doc:2.6/Manual/Animation/Timeline|Timeline]] for more info.
;See [[Keying Sets]] for more info.

== Auto Keyframe ==

[[File:Doc_kia_Cube03.PNG|frame|Timeline Auto Keyframe.]]

;Auto Keyframe is the red record button.
;Auto Keyframe adds keyframes automatically to the set frame after setting the location, rotation, scale, etcetra, of the selected object in the 3D View.

;See [[Doc:2.6/Manual/Animation/Timeline|Timeline]] for more info.

== Properties ==

[[File:Doc_kia_Cube04.PNG|frame|Timeline Keying Sets.]]

;Keyframes can be used to animate lots of properties in blender.
;To add keyframes to a property on the UI, {{Shortcut|RMB}} the property, then select Insert Single Keyframe, or Insert Keyframes.
;Insert Keyframes will add a keyframes to the set of properties.

== Keyboard ==

;The keyboard can also be used to add keyframes.

:{{Shortcut|I}}: Insert keyframe to the set frame.
:{{Shortcut|Alt+I}}: Remove keyframe from the set frame.
:{{Shortcut|Alt+Shift+I}}: Remove all keyframes from the UI property.

== Animation Editors ==

;Most of the low level settings for the keyframes are found in the [[Doc:2.6/Manual/Animation/Editors/Graph|Graph Editor]].
;You can add keyframes to channels that have existing keyframes in several animation editors, which are described in other pages:

*[[Doc:2.6/Manual/Animation/Timeline|Timeline]]
*[[Doc:2.6/Manual/Animation/Editors/Graph|Graph Editor]]
*[[Dope Sheet]]
*[[Doc:2.6/Manual/Animation/Editors/NLA|NLA Editor]]
