2D Graphing Library

thingiverse

This OpenSCAD library allows you to create 2D representations of equations (cartesian, polar, or parametric) and export them as DXF files or extrude into interesting objects like ellipsoids. Although inefficient, slow, and a bit buggy, it works for the most part. Future enhancements may include 3D function support if polyhedrons can be mastered in OpenSCAD. To use the library, define your equation function (f(x) for cartesian, r(theta) for polar, or x(t) and y(t) for parametric), set optional parameters such as lower and upper bounds, line thickness, polygon count, and drawing type (cartesian by default), then call the 2dgraph function. For example, use 2dgraph([-10, 10], 2, $fn=100) to create a graph with parameters ranging from -10 to 10 with 100 polygons.
