Parameters

time

Type: SystemTimeSpan
The animation time.

defaultSource

Type: DigitalRune.Mathematics.AlgebraVector3F
In: The source value that should be used by the animation if the animation does not have its own source value.

defaultTarget

Type: DigitalRune.Mathematics.AlgebraVector3F
In: The target value that should be used by the animation if the animation does not have its own target value.

result

Type: DigitalRune.Mathematics.AlgebraVector3F
Out: The value of the animation at the given time.

The method GetValueCore(TimeSpan, T, T, T) implements the animation function. It is called automatically by GetValue(TimeSpan, T, T, T) to compute the current animation value.

Note that the parameters are passed by reference. defaultSource and defaultTarget are input parameters. The resulting animation value is stored in result.

The values of the defaultSource and the defaultTarget parameter depends on where the animation is used. If the animation is used to animate an IAnimatablePropertyT then the values depend on the position of the animation in the composition chain:

• If the animation has replaced another animation using SnapshotAndReplace: defaultSource is the last output value of the animation which was replaced and defaultTarget is the base value of the animated property.
• If the animation is the first in an animation composition chain: defaultSource and defaultTarget are the base value of the animated property.
• If the animation is not the first in an animation composition chain: defaultSource is the output of the previous stage in the composition chain and defaultTarget is the base value of the animated property.

Notes to Inheritors: The sole purpose of this method is to evaluate the animation function at the given time. All other tasks (handling of additive animations, animation blending) are automatically handled by the base class.

The parameter time contains the local time of the animation. (Any parameters such as Delay, Duration, Speed, or LoopBehavior have already been applied.)
