SplineLib

Library for manipulating 2D and 3D splines. Functionality included:

  • Creation from Bezier, Hermite, and Catmull-Rom forms
  • Creation of an array of splines from an array of points and tension value, or Bezier hull points, or Hermite tangents.
  • Creation of arcs and circles
  • Evaluation of position, velocity, acceleration, curvature, and tangent frame
  • Length measurement
  • Finding bounds
  • Offsetting (e.g., for stroking) and reversing splines
  • Splitting and re-joining of single splines
  • Subdivision of runs of splines either evenly, for flatness, or to be linear in arc length
  • Finding the closest point on a run of splines
  • Finding where runs of splines intersect, or a run of splines self-intersects
  • Helpers for advancing a point along a spline at some given velocity

To build and run the test app:

c++ --std=c++11 Splines.cpp SplinesTest.cpp -o splines && ./splines

Or add those files to your favourite IDE.
