transform

public final void transform(double[] sphere,
                            double[] plane)
Description copied from class: Transformer
Convert a single point where the output vector is supplied.

Specified by:
transform in class Transformer
Parameters:
sphere - The input vector.
plane - The output vector, it may be the same as the input vector if the dimensionalities are the same. All transformers are expected to work with aliased inputs and output.
