Constructor Detail

MicrosphereInterpolatingFunction

public MicrosphereInterpolatingFunction(double[][] xval,
                                        double[] yval,
                                        int brightnessExponentIn,
                                        int microsphereElements,
                                        UnitSphereRandomVectorGenerator rand)

Parameters:

xval - 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 - Values for the interpolation points.

brightnessExponentIn - 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 an array has zero-length.

NullArgumentException - if an argument is null.
