Field Details

dimension

private final int dimension

Deprecated.

Space dimension.

microsphere

private final List<MicrosphereInterpolatingFunction.MicrosphereSurfaceElement> microsphere

Deprecated.

Internal accounting data for the interpolation algorithm. Each element of the list corresponds to one surface element of the microsphere.

brightnessExponent

private final double brightnessExponent

Deprecated.

Exponent used in the power law that computes the weights of the sample data.

samples

private final Map<RealVector,Double> samples

Deprecated.

Sample data.

Constructor Details

MicrosphereInterpolatingFunction

public MicrosphereInterpolatingFunction(double[][] xval,
 double[] yval,
 int brightnessExponent,
 int microsphereElements,
 UnitSphereRandomVectorGenerator rand)
                                 throws DimensionMismatchException,
NoDataException,
NullArgumentException

Deprecated.

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.

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 an array has zero-length.

NullArgumentException - if an argument is null.

Method Details

value

public double value(double[] point)
             throws DimensionMismatchException

Deprecated.

Description copied from interface: MultivariateFunction

Compute the value for the function at the given point.

Specified by:

value in interface MultivariateFunction

Parameters:

point - Interpolation point.

Returns:

the interpolated value.

Throws:

DimensionMismatchException - if point dimension does not math sample

cosAngle

private double cosAngle(RealVector v,
 RealVector w)

Deprecated.

Compute the cosine of the angle between 2 vectors.

Parameters:

v - Vector.

w - Vector.

Returns:

the cosine of the angle between v and w.
