                                           int iSizeY,
                                           int iSizeZ)

  Create an image of the specified dimensions and fill it to contain a mapping of the coordinates based on the 3D lattice of B-spline control points.

  Parameters:

  iSizeX - int Number of samples along x axis of image.

  iSizeY - int Number of samples along y axis of image.

  iSizeZ - int Number of samples along z axis of image.

  Returns:

                              WildMagic.LibFoundation.Mathematics.Vector3f kPoint)

  Retrieve the position of the specified control point.

  Parameters:

  iControlX - int Identifies control point in 3D lattice.

  iControlY - int Identifies control point in 3D lattice.

  iControlZ - int Identifies control point in 3D lattice.

                          WildMagic.LibFoundation.Mathematics.Vector3f kPos)

  Return the B-Spline evaluation for the given input values. The evaluation is based on the 3D evaluation of the B-Spline basis (one for each axis) and the 3D lattice of control points.

  Parameters:

  iSampleX - int Sample index along X axis which determines an input value in the [0,1] for that axis' B-Spline basis evaluation.

  iSampleY - int Sample index along Y axis which determines an input value in the [0,1] for that axis' B-Spline basis evaluation.

  iSampleZ - int Sample index along Z axis which determines an input value in the [0,1] for that axis' B-Spline basis evaluation.

  kPos - Point3f 3D coordinates resulting from evaluation.

• getPosition

                          WildMagic.LibFoundation.Mathematics.Vector3f kPos)

  Return the B-Spline evaluation for the given input values. The evaluation is based on the 3D evaluation of the B-Spline basis (one for each axis) and the 3D lattice of control points. This method is used for interpolating between the discrete samples.
