I created and released my first cinder block and wanted to put it out there to see if it’s useful to anyone else.

What it does is simplifies and returns a smoothed out, simplified Path2d object based on a vector of Vec2fs that you pass to it. It uses the same algorithm that paperjs uses, but c++-ified. It’s a slightly modified version of An Algorithm for Automatically Fitting Digitized Curves from “Graphic Gems.”

There are 2 samples in there.

• PathSimplification: Drag to draw a line on the screen. Once the line is finished, it analyzes and smooths out the line, letting you know how many lines you saved. It’s based on this paperjs example.
• ContinuousPath: Analyzes and smooths a path as you draw it. Could be good for making a drawing application.
