Bezier

Fast and lightweight class for using the Bezier curves of any order in C++

Algorithm implementations are based on A Primer on Bezier Curves by Pomax

Key Features

Any number of control points
Fast operations on curves
Dynamic manipulation
Composite Bezier curves (polycurves)

CMake find_package() compatible!

find_package(Bezier)
target_link_libraries(target bezier)

Implemented methods

Get value, derivative, curvature, tangent and normal for parameter t
Get t from projection any point onto a curve
Get precise length for any part of curve
Get a derivative curve (hodograph)
Split into two subcurves
Find curve roots and bounding box
Find points of intersection with another curve
Elevate/lower order
Apply parametric and geometric continuities
etc.

Wish list

- [ ] Polycurve - oversee continuities between consecutive sub-curves
- [ ] Polycurve - propagation of sub-curve manipulation depending on continutiy
- [ ] Bezier shapes
- [ ] More sophisticated example

Dependencies
