Constructor
new KeyframeTrack( name : string, times : Array.<number>, values : Array.<(number|string|boolean)>, interpolation : InterpolateLinear | InterpolateDiscrete | InterpolateSmooth )
Constructs a new keyframe track.
| name |
The keyframe track's name. |
| times |
A list of keyframe times. |
| values |
A list of keyframe values. |
| interpolation |
The interpolation type. |
Properties
.DefaultInterpolation : InterpolateLinear | InterpolateDiscrete | InterpolateSmooth
The default interpolation type of this keyframe track.
Default is InterpolateLinear.
.TimeBufferType : TypedArray | Array
The time buffer type of this keyframe track.
Default is Float32Array.constructor.
.ValueBufferType : TypedArray | Array
The value buffer type of this keyframe track.
Default is Float32Array.constructor.
.ValueTypeName : string
The value type name.
Default is ''.
.name : string
The track's name can refer to morph targets or bones or possibly other values within an animated object. See PropertyBinding#parseTrackName for the forms of strings that can be parsed for property binding.
.times : Float32Array
The keyframe times.
.values : Float32Array
The keyframe values.
Methods
.InterpolantFactoryMethodDiscrete( result : TypedArray ) : DiscreteInterpolant
Factory method for creating a new discrete interpolant.
| result |
The result buffer. |
- Returns: The new interpolant.
.InterpolantFactoryMethodLinear( result : TypedArray ) : LinearInterpolant
Factory method for creating a new linear interpolant.
| result |
The result buffer. |
- Returns: The new interpolant.
.InterpolantFactoryMethodSmooth( result : TypedArray ) : CubicInterpolant
Factory method for creating a new smooth interpolant.
| result |
The result buffer. |
- Returns: The new interpolant.
.clone() : KeyframeTrack
Returns a new keyframe track with copied values from this instance.
- Returns: A clone of this instance.
.getInterpolation() : InterpolateLinear | InterpolateDiscrete | InterpolateSmooth
Returns the current interpolation type.
- Returns: The interpolation type.
.getValueSize() : number
Returns the value size.
- Returns: The value size.
.optimize() : AnimationClip
Optimizes this keyframe track by removing equivalent sequential keys (which are common in morph target sequences).
- Returns: A reference to this animation clip.
.scale( timeScale : number ) : KeyframeTrack
Scale all keyframe times by a factor (useful for frame - seconds conversions).
| timeScale |
The time scale. |
- Returns: A reference to this keyframe track.
.setInterpolation( interpolation : InterpolateLinear | InterpolateDiscrete | InterpolateSmooth ) : KeyframeTrack
Defines the interpolation factor method for this keyframe track.
| interpolation |
The interpolation type. |
- Returns: A reference to this keyframe track.
.shift( timeOffset : number ) : KeyframeTrack
Moves all keyframes either forward or backward in time.
| timeOffset |
The offset to move the time values. |
- Returns: A reference to this keyframe track.
.trim( startTime : number, endTime : number ) : KeyframeTrack
Removes keyframes before and after animation without changing any values within the defined time range.
Note: The method does not shift around keys to the start of the track time, because for interpolated keys this will change their values
| startTime |
The start time. |
| endTime |
The end time. |
- Returns: A reference to this keyframe track.
.validate() : boolean
Performs minimal validation on the keyframe track. Returns true if the values
are valid.
- Returns: Whether the keyframes are valid or not.
Static Methods
.toJSON( track : KeyframeTrack ) : Object
Converts the keyframe track to JSON.
| track |
The keyframe track to serialize. |
- Returns: The serialized keyframe track as JSON.
