Class KeyFrame



  • public class KeyFrame
    extends Object
    A key frame is mainly defined by a time and a value, for some interpolation types, tangent/tension/bias/continuity is also used by calculating the final sampled value. Sampled values in a non-key-frame time position is interpolated by key-frames between the previous and next key-frames Value before/after the first/last key-frame are calculated by the Extrapolation class.

        Sets the key-frame's value.
        Parameters:
        value - New value
      • getInterpolation

        public Interpolation getInterpolation()
        Gets the key's interpolation type, list.data[index] defines the algorithm how the sampled value is calculated.
      • setInterpolation

        public void setInterpolation(Interpolation value)
        Sets the key's interpolation type, list.data[index] defines the algorithm how the sampled value is calculated.
        Parameters:
        value - New value
      • getTangentWeightMode

        public int getTangentWeightMode()
        Gets the key's tangent weight mode. The out tangent or the next in tangent can be customized by select correct WeightedMode
      • setTangentWeightMode

        public void setTangentWeightMode(int value)
        Sets the key's tangent weight mode. The out tangent or the next in tangent can be customized by select correct WeightedMode
        Parameters:
        value - New value
      • setStepMode

        public void setStepMode(StepMode value)
        Sets the key's step mode. If the interpolation type is Interpolation.CONSTANT, list.data[index] decides which key-frame's value will be used during interpolation. A StepMode.PREVIOUS_VALUE means the left key-frame's value will be used A StepMode.NEXT_VALUE means the next right key-frame's value will be used
        Parameters:
        value - New value
