Introduction

Rhinoceros (often abbreviated to Rhino) is a commercial 3D computer graphics and computer-aided design (CAD) application software. Rhino is well known for its freeform NURBS (Non-Uniform Rational B-Splines) surface modeling capabilities which offers great flexibility and presicion to handle complex shapes. Rhino also supports a vast array of plugins, allowing it to be tailored to specific industries or design challenges. A good example is Grasshopper, a node-based visual programming language add-on for Rhino that allows for advanced generative and algorithmic design capabilities.

This Rhino tutorial is organized in three sections:

1. Composition of Rhino's interface in detail;
2. Logic and modelling of basic geometry like curve and surface;
3. Commands and modelling techniques frequently used during the model process.
