Base

  • Floating point comparison and epsilon
  • Conversion radian-degree, date time to seconds

Solver

  • Analytical solution of linear, quadratic, cubic and quartic polynomial equations
  • Numerical general polynomial equation root solver
  • General root solver with either bisection or secant method
  • First and second order regression with optional weight

Functions

  • Qudratic root
  • Cubic root
  • Quartic root
  • Fast sin evaluation [-PI/2, -PI/2]
  • Normalize angle
  • Nomerical stable sin-cos evaluation
  • Factorial; ulong (n ⇐ 20) and double
  • Fibonacci; ulong (n ⇐ 93), double and Binet
  • Greatest common divisor (GDC)
  • IsPrime; no cache; ~3s for max long / 10

Statistics

  • Arithmetic mean and variance, optional weighted
  • Averageing / mean of angles
  • Centered moving averageing, optional weighted

Geometry

  • Convex hull 2D (Jarvis march & Andrew's monotone chain; point reduction algorithm)
  • Minimal bounding circle 2D
  • Minimal bounding circle on sphere 3D
  • Perpendicular (segment / line ) distance (2D & 3D)
  • Trajectory Hausdorff Distance (2D & 3D)
  • Filter of significant points based on Minimum Description Length Principle (2D & 3D)
  • k-d tree search for vector & segment (2D & 3D)

Data structures

  • BoundingBox
  • BoundingRect
  • Circle2D
  • Circle3D
  • CubicBezier2D
  • CubicBezier3D
  • Color
  • Polar3D
  • Polynomial
    • Division by real roots (linear root), and imaginary and conjugated (quadratic root)
    • Evaluation of polynomial and its derivative and integral
  • Segment2D
  • Segment3D
  • Sparse array
  • Vector2D
  • Vector3D

GPS

  • GpsPoint
  • GpsTrack
  • Flatten to local 2D; single object and collection
  • Smoothing of holes (missing GPS signal, same position) by reducing variance
  • Geodesy
    • Haversine distance
  • GridLookup / NeighbourDistanceCalculator : Finding neighbors of two GPS tracks in O(N)
  • Intersection / overlapping (overestimating) of two GPS tracks
    • grid / lookup table based - fastest and pretty precise depending on given resolution
    • minimal rectangular bounding box
    • minimal circle on sphere - slow on 1st call to calculate min circle

Clustering

  • DBScan vector / segment for 2D / 3D
  • TraClus (Trajectory Clustering: A Partition-and-Group Framework) for 2D and 3D
  • Finding trajectory neighborhoods for 2D and 3D
  • GPS segment clustering; finding common segments for locally collocated GPS tracks or globally

Gfx

  • PNG, PPM and PGM bitmap writer
  • Simple bitmap
  • RGB color bitmap
  • Line draw - Bresenham and anti-aliasing (Xiaolin Wu's line algorithm)
  • Point plot (anti-aliasing)
  • Heatmap for arbitrary set of GPS tracks with color schemes
