## Topics

### Initializers

[`init(rawValue:)`](/documentation/QuartzCore/CAAnimationCalculationMode/init(rawValue:))

### Type Properties

[`cubic`](/documentation/QuartzCore/CAAnimationCalculationMode/cubic)

Smooth spline calculation between keyframe values.

[`cubicPaced`](/documentation/QuartzCore/CAAnimationCalculationMode/cubicPaced)

Cubic keyframe values are interpolated to produce an even pace throughout the animation.

[`discrete`](/documentation/QuartzCore/CAAnimationCalculationMode/discrete)

Each keyframe value is used in turn, no interpolated values are calculated.

[`linear`](/documentation/QuartzCore/CAAnimationCalculationMode/linear)

Simple linear calculation between keyframe values.

[`paced`](/documentation/QuartzCore/CAAnimationCalculationMode/paced)

Linear keyframe values are interpolated to produce an even pace throughout the animation.
