Class MovingMatrix4

java.lang.Object
org.sunflow.math.MovingMatrix4

public final class MovingMatrix4 extends Object
This class describes a transformation matrix that changes over time. Note that while unlimited motion segments are supported, it is assumed that these segments represent equidistant samples within a given time range.
  • Constructor Details

    • MovingMatrix4

      public MovingMatrix4(Matrix4 m)
      Constructs a simple static matrix.
      Parameters:
      m - matrix value at all times
  • Method Details

    • setSteps

      public void setSteps(int n)
      Redefines the number of steps in the matrix. The contents are only re-allocated if the number of steps changes. This is to allow the matrix to be incrementally specified.
      Parameters:
      n -
    • updateData

      public void updateData(int i, Matrix4 m)
      Updates the matrix for the given time step.
      Parameters:
      i - time step to update
      m - new value for the matrix at this time step
    • getData

      public Matrix4 getData(int i)
      Get the matrix for the given time step.
      Parameters:
      i - time step to get
      Returns:
      matrix for the specfied time step
    • numSegments

      public int numSegments()
      Get the number of matrix segments
      Returns:
      number of segments
    • updateTimes

      public void updateTimes(float t0, float t1)
      Update the time extents over which the matrix data is changing. If the interval is empty, no motion will be produced, even if multiple values have been specified.
      Parameters:
      t0 -
      t1 -
    • inverse

      public MovingMatrix4 inverse()
    • sample

      public Matrix4 sample(float time)
