public class InterpolatingMicrosphere2D extends InterpolatingMicrosphere
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 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.
      Throws:
      NotStrictlyPositiveException - if size <= 0.
      NotPositiveException - if darkThreshold < 0.
      OutOfRangeException - if maxDarkFraction does not belong to the interval [0, 1].
