InterpolateValue(Matrix, Double)

Returns the interpolated value of a specific key frame at the progress increment provided.

Declaration

public Matrix InterpolateValue(Matrix baseValue, double keyFrameProgress)

Parameters

Type	Name	Description
Matrix	baseValue	The value to animate from.
System.Double	keyFrameProgress	A value between 0.0 and 1.0, inclusive, that specifies the percentage of time that has elapsed for this key frame.

Returns

Type	Description
Matrix	The output value of this key frame given the specified base value and progress.
