This book introduces you to the exciting world of generative art (artwork that are solely or partially created with the use of an autonomous system) through the medium of SVG and JavaScript. More specifically, it will teach the use of Graphery SVG (gySVG), a JavaScript library that closely mirrors the SVG spec and makes scripting SVG very intuitive and enjoyable. Armed with gySVG, the reader will be taught tried and trusted techniques in producing generative imagery. Each chapter will build upon the previous one, and those completely new to programming will be given a primer to help them find their feet.Beginning with a simple generative sketch that illustrates, and then explains, fundamental programming concepts such as variables, data types, operators, loops, conditionals and functions - the reader will go on to explore the power of Scalable Vector Graphics, how to play with randomness and regularity, how to use noise to create organic variance, and how to make sketches interactive and dynamic. More advanced topics will then be tackled, such as paths, filter effects, trigonometry, shape packing, flow fields and fractals.It will be a fun journey, easy to follow, peppered with plenty of attractive sketches throughout. The goal will be to visually inspire readers with compelling examples of what¿s possible - rather than bare-bones, make-do illustrations - thereby breathing life into the underlying theoretical concepts.WHAT YOU'LL LEARN: Generative art is and its creative processHow to use the gySVG library locally with Node.js or online via CodepenConsolidation of JavaScript fundamentals, using modern ES6+ syntax Creating a variety of SVG shapes generatively Creating iterative variations of sketches by randomizing parametersUsing noise to create organic varianceCreating complex SVG paths generativelyHow to make sketchesinteractiveWHO IS IT FOR: Web developers and designers and creative coders with an interest in digital and generative art as well as artists who are interested in learning to code with JavaScript.
