Vectorize is a free image tracing plug-in for Rhino.
Vectorize supports both Rhino 6 and Rhino 7 for Windows and Mac. Use Rhino 7's new PackageManager command to download and install the latest version.
The inspiration for Vectorize comes from Gérard Bouteau, a long time Rhino user, trainer, and programmer, who developed a plug-in named Trace. Unfortunately for all of us, Gérard passed away unexpectedly in the spring of 2020. Because of this untimely passing, he was never able to port his popular plug-in to Rhino 7 and beyond.
Vectorize, like Trace, is based off the famous Potrace by Peter Selinger, whose application transforms a bitmap into a soft, scalable image made up of vectors. The plug-in uses a C# translation named CsPotrace written by Wolfgang Nagl.
