OpenSCAD Conic Bezier Curve

thingiverse

A Conic Bézier Curve, also known as a Quadratic Bezier or a Bezier with three control points, can be created using OpenSCAD. This curve type, also called 'Conic Arcs' or 'Parabolic Segments,' was developed by Pierre Bézier and is used in TrueType fonts. In OpenSCAD, the code for this 3-point Bezier curve is simple, taking advantage of the program's built-in vector math. To use the curve, download the .scad file, copy/paste the BezConic module into your own code, and call it with three points and a step value. Fun facts include that Bézier curves are named after Pierre Bézier, who worked at Renault, and that 'conic' refers to their parabolic nature, similar to conic sections in mathematics. An example .stl file is provided for testing purposes.
