Houjing

a toolbox of all things about curve.

Features

crates/houjing-bezier provcides the core geometry manipulation utilities for curves

• Data structures for representing Bezier curves (cubic and quadratic segments)
• parse/export:
  • SVG path M 10,20 C 20,30 30,40 40,50 Z.
  • json format {"x": 0.0, "y": 0.0, "on": true}, {"x": 1.0, "y": 1.0, "on": false}, {"x": 2.0, "y": 0.0, "on": true}
• Fitting curves
  • least square method (see Cubic Bezier Fitting with Least Squares)
    • simple least square
    • Alternating method (nearest point and gauss-newton)
    • an improvised gauss-newton with lineseach

crates/houjing-main: the main playground. The idea of developing using a game engine @bevy is stolen from @eliheuer
