dimension
- Space dimension.elements
- Number of surface elements of the microsphere.exponent
- Exponent used in the power law that computes themaxDarkFraction
- Maximum fraction of the facets that can be dark.
If the fraction of "non-illuminated" facets is larger, no estimation
of the value will be performed, and the background
value will
be returned instead.darkThreshold
- Value of the illumination below which a facet is
considered dark.background
- Value returned when the maxDarkFraction
threshold is exceeded.sharedSphere
- Whether the sphere can be shared among the
interpolating function instances. If true
, the instances
will share the same data, and thus will not be thread-safe.noInterpolationTolerance
- When the distance between an
interpolated point and one of the sample points is less than this
value, no interpolation will be performed (the value of the sample
will be returned).NotStrictlyPositiveException
- if dimension <= 0
or elements <= 0
.NotPositiveException
- if exponent < 0
.NotPositiveException
- if darkThreshold < 0
.OutOfRangeException
- if
maxDarkFraction
does not belong to the interval [0, 1]

microsphere
- Microsphere.exponent
- Exponent used in the power law that computes the
weights (distance dimming factor) of the sample data.sharedSphere
- Whether the sphere can be shared among the
interpolating function instances. If true
, the instances
will share the same data, and thus will not be thread-safe.noInterpolationTolerance
- When the distance between an
interpolated point and one of the sample points is less than this
value, no interpolation will be performed (the value of the sample
will be returned).NotPositiveException
- if exponent < 0

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 d
is thus the dimension of the space).yval
- the values for the interpolation pointsDimensionMismatchException
- if the space dimension of the
given samples does not match the space dimension of the microsphere.NoDataException
- if an array has zero-length.NullArgumentException
- if the arguments are null
