Class InterpolatingMicrosphere2D
java.lang.Object
org.hipparchus.analysis.interpolation.InterpolatingMicrosphere
org.hipparchus.analysis.interpolation.InterpolatingMicrosphere2D
Utility class for the
MicrosphereProjectionInterpolator
algorithm.
For 2D interpolation, this class constructs the microsphere as a series of
evenly spaced facets (rather than generating random normals as in the
base implementation).-

InterpolatingMicrosphere2D
public InterpolatingMicrosphere2D(int size, double maxDarkFraction, double darkThreshold, double background) Create a sphere from vectors regularly sampled around a circle.- Parameters:
size
- Number of surface elements of the sphere.maxDarkFraction
- 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 thebackground
value will be returned instead.darkThreshold
- Value of the illumination below which a facet is considered dark.background
- Value returned when themaxDarkFraction
threshold is exceeded.- Throws:
MathIllegalArgumentException
- ifsize <= 0
.MathIllegalArgumentException
- ifdarkThreshold < 0
.MathIllegalArgumentException
- ifmaxDarkFraction
does not belong to the interval[0, 1]
