Constructor Detail

• MovingMatrix4

  public MovingMatrix4(Matrix4 m)

  Constructs a simple static matrix.

  Parameters:

  m - matrix value at all times

Method Detail

• 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)
