Today we introduce you the Spiral Raster script which converts raster images into vector spirals that look like variable width paths. This script works with the Paper.js. Yaroslav Tabachkovsky, the developer of Mesh Tormentor, improved the original script. Now we have an opportunity to choose one of three tracing methods and control parameters of the base grid. And the most important is that you can export the tracing result as vector files in the SVG format. In this article you’ll find the Spiral Raster script and the instruction for its use.
