دانلود کتاب طراحی پارامتریک و مولد با راینو پایتون و گرس‌هاپر: کاوشی در فرم‌یابی و تولید رویه‌ای

It’s been many years since I created a Grasshopper (GH) script for the first time, and I still remember the excitement—building a node graph with intuitive drag-and-drops, and with just a few sliders here and there, an explosion of forms appears in the Rhino viewport. This is what I want to show you in this book—how to start with an idea, an interesting silhouette or arrangement of shapes, and translate it into a parametric model in GH that allows the most diverse and aesthetic variations. The book is organized into two parts. The first part (Chapters 1–7), gets you up to speed with Grasshopper and Python 3 basics, and shows you how to generate models like attractors, tessellations, spirals, voxels, cracks, and wireframes. The second part covers Chapters 8–13 and provides five advanced application workshops, including weaving meshes, creating sliceforms, generating Breps from images, making fractals and tree-like canopies from L-systems, and creating skylines from building footprint (Geographic Information System, GIS) data. The final chapter takes you through packaging GH scripts into apps suitable for online publication. I’ve intentionally structured the book to utilize built-in GH components as much as possible, with a few custom Python 3 Script nodes—although there is a plethora of GH apps on food4rhino.com that will do seemingly anything, there is value in learning how to do things yourself, for when your idea is so unique that no app will do precisely what you want. In addition, apps often become out of date with new Rhino releases, with no guarantee when or if they will be updated. That said, we’ll still take advantage of a few popular GH plugins such as LunchBox and Weaverbird throughout the book.
