animation_curve_optimize

Functions

• compute_keyframe_value_effect(key_middle, key_previous, key_next) ⇒ number

Computes importance by checking Position AND Slope integrity. Uses exact derivative calculation instead of neighbor sampling

• animation_curve_optimize(curve, [error_tolerance]) ⇒ number

Will remove keyframes that do not affect the shape of the curve significantly. The error tolerance determines the significance degree. Intended to reduce the complexity of a curve to improve performance and lower memory usage

compute_keyframe_value_effect(key_middle, key_previous, key_next) ⇒ number

Computes importance by checking Position AND Slope integrity. Uses exact derivative calculation instead of neighbor sampling

Kind: global function
Returns: number - value delta if the middle frame is removed, the higher this value - the more important the middle keyframe is

key_middle	Keyframe
key_previous	Keyframe
key_next	Keyframe

animation_curve_optimize(curve, [error_tolerance]) ⇒ number

Will remove keyframes that do not affect the shape of the curve significantly. The error tolerance determines the significance degree. Intended to reduce the complexity of a curve to improve performance and lower memory usage

Kind: global function
Returns: number - number of removed keys, 0 if curve was unchanged

Param	Type	Description
curve	AnimationCurve	The curve to optimize. The curve is modified in place.
[error_tolerance]	number	how much of a loss to accept, this is relative to normalized value bounds of the curve
