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. Today we’re releasing a new program, StippleGen, which can generate stipple diagrams from images, using Secord’s algorithm. StippleGen is free and open source software, written in the Processing development environment. Other programs StippleGen Controls

GRADIENT SUBDIVISION This definition uses graph values to subdivide surfaces in gradient type patterns 1. Define a surface2. Extract guide curves from the surface2. 5. GH Version Tip You can do this process also with UV domains and isotrim, which makes ashorter definition but takes longer to compute. Tutorials Introduction to Grasshopper Videos by David Rutten. Wondering how to get started with Grasshopper? Look no further. Spend an some time with the creator of Grasshopper, David Rutten, to learn the fundamental of Grasshopper. No experience necessary.

русский Rhino Grasshopper Вольный перевод "The Grasshopper Primer, Second Edition". Главное окно Для запуска плагина набираем "Grasshopper" в командной строке Rhino, жмем Enter и видим главное окно Grasshopper (далее ГХ): Интерфейс окна содержит элементы, большинство из которых знакомы пользователям Rhino. A. Данное меню подобно обычному для Windows-приложений меню, за исключением дополнительного элемента управления, расположенного справа (B). B. Как описано выше, данное выпадающее меню можно использовать для переключения между открытыми файлами ГХ. C. Эта область содержит все категории доступных в ГХ компонентов. При этом появляется выпадающая панель со всеми компонентами данной категории. Элементы также можно выбирать по имени, для этого достаточно дважды щелкнуть мышью в любом месте листа. D. Строка заголовка окна редактора имеет отличия в поведении от других диалоговых окон Windows. E. Панель инструментов листа предоставляет быстрый доступ к часто используемым инструментам листа. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.

Grasshopper - Best practices - Modelical Introduction In order to have a clear organization in our Grasshopper files, that will allow an external person to understand what is done, it is convenient to set a number of good practices for its use. We have used a function that models a parametric table as an example to follow in this guide. The parameters that can be modified in it are its general dimensions (length, width and height), the top board and legs thickness, and the distance between the axes of the legs. Firstly, we have created a template, we have another one for Rhino 5, in which has been added Modelical´s logo and a space to add a description of the file. Data entry parameters The description of the file is formed by: Title – Author.Description.Parameters description.File description.Date.Version.Rhino file location if needed. In order to keep a well organized workspace and avoid it to become a mess of cables, we should keep the following work habits. Finally, we will set the wire display of the last component to Hidden.
