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