- All Implemented Interfaces:
    MultivariateInterpolator

  Deprecated.
  Code will be removed in 4.0. Use `InterpolatingMicrosphere` and `MicrosphereProjectionInterpolator` instead.

      @Deprecated
      public class MicrosphereInterpolator
      extends Object
      implements MultivariateInterpolator

  Interpolator that implements the algorithm described in William Dudziak's MS thesis.
  Since:
    2.1

    - #### DEFAULT_MICROSPHERE_ELEMENTS

          public static final int DEFAULT_MICROSPHERE_ELEMENTS

      Deprecated.
      Default number of surface elements that composes the microsphere.

        Constant Field Values

    - #### DEFAULT_BRIGHTNESS_EXPONENT

          public static final int DEFAULT_BRIGHTNESS_EXPONENT

      Deprecated.
      Default exponent used the weights calculation.

        Constant Field Values

  - ### Constructor Detail

    - #### MicrosphereInterpolator

          public MicrosphereInterpolator()

      Deprecated.
      Create a microsphere interpolator with default settings. Calling this constructor is equivalent to call `MicrosphereInterpolator(MicrosphereInterpolator.DEFAULT_MICROSPHERE_ELEMENTS, MicrosphereInterpolator.DEFAULT_BRIGHTNESS_EXPONENT)`.

    - #### MicrosphereInterpolator

          public MicrosphereInterpolator(int elements,
                                 int exponent)
                                  throws NotPositiveException,
                                         NotStrictlyPositiveException

      Deprecated.
      Create a microsphere interpolator.
      Parameters:
        `elements` - Number of surface elements of the microsphere.
        `exponent` - Exponent used in the power law that computes the weights (distance dimming factor) of the sample data.
      Throws:
        `NotPositiveException` - if `exponent < 0`.
        `NotStrictlyPositiveException` - if `elements <= 0`.

  - ### Method Detail

    - #### interpolate

          public MultivariateFunction interpolate(double[][] xval,
                                         double[] yval)
                                           throws DimensionMismatchException,
                                                  NoDataException,
                                                  NullArgumentException

      Deprecated.
      Computes an interpolating function for the data set.
      Specified by:
        `interpolate` in interface `MultivariateInterpolator`
      Parameters:
        `xval` - the arguments for the interpolation points. `xval[i][0]` is the first component of interpolation point `i`, `xval[i][1]` is the second component, and so on until `xval[i][d-1]`, the last component of that interpolation point (where `d` is thus the dimension of the space).
        `yval` - the values for the interpolation points
      Returns:
        a function which interpolates the data set
      Throws:
        `DimensionMismatchException` - when the array dimensions are not consistent.
        `NoDataException` - if an array has zero-length.
        `NullArgumentException` - if the arguments are `null`.
