StippleGen: Weighted Voronoi stippling and TSP paths in Processing

StippleGen: Weighted Voronoi stippling and TSP paths in Processing
One of the perennial problems that we come across in a variety of contexts, including CNC artwork and producing artwork for the Egg-Bot, is the difficulty of creating good-quality toolpaths– i.e., vector artwork representing halftones –when starting from image files. One of the finest solutions that we’ve ever come across is Adrian Secord’s algorithm, which uses an iterative relaxation process to optimize a weighted Voronoi diagram, producing a set of points (stipples) that can closely approach the appearance of a traditional stipple drawing. Another important technique is “TSP art,” where the image is represented by a single continuous path. You can generate a path like this by connecting all of the dots in a stipple diagram. Designing a route that visits each dot exactly once is an example of the famous Travelling Salesman Problem (or TSP). Today we’re releasing a new program, StippleGen, which can generate stipple diagrams from images, using Secord’s algorithm. Other programs

Tutorials > Using Actions to Automate Tasks in Photoshop While Adobe Photoshop has a host of automation tools, one of the most versatile and powerful of them is called an action. In fact, some of the other automation commands, such as batches and droplets, derive their functionality from actions. An action is like a macro or script; however, while scripts have a reputation for being confusing and difficult, actions are very easy to create. If you know how to use Photoshop, you know most of what you need to create your own actions. For example, let's say that you have 100 digital photos that you'd like to post on the Internet. Fallen Angels Rescued Parametrically Boston Valley Terra Cotta restored four decorative angels from the 23rd floor of a Beaux Arts building in New York. (courtesy Boston Valley Terra Cotta) Classically trained sculptors breath new life into four 20-foot angels with the help of Rhino. When Old Structures Engineering engaged Boston Valley Terra Cotta in the restoration of the 1896 vintage Beaux-Arts building at 150 Nassau Street in New York—one of the city’s original steel frame structures—the four decorative angelic figures, or seraphs, that adorned the corners of the uppermost story were in serious decay.

Make a preset Start with an image (any image will work (RAW is best) here is one that I shot recently of Lina and I’m just going to apply an effect. Strokes Maker 2 About the project Strokes Maker is a unique software product intended for creation of vector engravings and artistic vectorization of raster images. The software uses original algorithms for calculation of vector strokes based on initial raster images. It renders halftones and image relief. Thousands of strokes interrupt and intersect under different angles, turn from continuous to dotted line, disappear and emerge again, changing their path and forming a unique of a kind high quality vector image. One incorrectly calculated stroke, like one false note in a symphony, can spoil the harmony of lines making up a single image.

Initially designed with Guilloché patterns in mind, ZebraTrace effectively combines a function plotter and a bitmap tracer, where thickness of vector lines depends on the lightness of pixels in a background image. Here's a trace of Mark Twain's photo with wavy horizontal lines: Note how vector lines become become thinner towards the well-lit face. You can control basic aspects of tracing: amount of lines, min/max thickness of lines etc. ZebraTrace currently doesn't make use of PowerStroke LPE in upcoming Inkscape 0.49, so it has to create paths with lots of nodes to directly operate on later.
