Constructor Detail

MicrosphereInterpolatingFunction

public MicrosphereInterpolatingFunction(double[][] xval,
                                        double[] yval,
                                        int brightnessExponent,
                                        int microsphereElements,
                                        UnitSphereRandomVectorGenerator rand)
                                 throws DimensionMismatchException,
                                        NoDataException
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 dimension is thus the dimension of the sampled space).
yval - the values for the interpolation points
brightnessExponent - Brightness dimming factor.
microsphereElements - Number of surface elements of the microsphere.
rand - Unit vector generator for creating the microsphere.
Throws:
DimensionMismatchException - if the lengths of yval and xval (equal to n, the number of interpolation points) do not match, or the the arrays xval[0] ... xval[n], have lengths different from dimension.
NoDataException - if there are no data (xval null or zero length)
