Generative Art in Go

A creative guide

About the Book

Generative art is a unique form of artistic expression, building bridges between computer programming, randomness, and visual aesthetics. It has kept my imagination for over a decade. While I have never been particularly skilled at drawing, I have always been amazed by what one could achieve with a couple of lines of code.

This book will introduce readers to graphics programming in the Go programming language context through a series of concise examples. It will also guide them in implementing their version of one of my favorite generative art sketches. As a bonus, readers will learn how to turn their command-line sketches into interactive Web applications, using WebAssembly and Web technology's latest standards.

A seasoned software developer with about a decade of professional experience behind my back. My first real touch with programming dates about a decade further back. Throughout my career, I have had the chance to learn a lot, and I believe that the time has come for me to contribute my knowledge back to the developer community.
