Aerotwist - Getting Started with Three.js

## Introduction I have used Three.js for some of my experiments, and it does a really great job of abstracting away the headaches of getting going with 3D in the browser. With it you can create cameras, objects, lights, materials and more, and you have a choice of renderer, which means you can decide if you want your scene to be drawn using HTML 5’s canvas, WebGL or SVG. And since it’s open source you could even get involved with the project. For all the awesomeness of Three.js, there can be times where you might struggle. The basics I will assume that you have at least a passing knowledge of 3D, and reasonable proficiency with JavaScript. In our 3D world we will have some of the following, which I will guide you through the process of creating: A scene A renderer A camera An object or two (with materials) You can, of course, do some crazy things, and my hope is that you will go on to do that and start to experiment with 3D in your browser.

Pixel Shaders: An Interactive Introduction to Graphics Programming A Primer on Bézier Curves Preface In order to draw things in 2D, we usually rely on lines, which typically get classified into two categories: straight lines, and curves. The first of these are as easy to draw as they are easy to make a computer draw. Give a computer the first and last point in the line, and BAM! straight line. No questions asked. Curves, however, are a much bigger problem. They're named after Pierre Bézier, who is principally responsible for getting them known to the world as a curve well-suited for design work (working for Renault and publishing his investigations in 1962), although he was not the first, or only one, to "invent" these type of curves. So, what if you need to program them yourself? —Pomax (or in the tweetworld, @TheRealPomax) Note: virtually all Bézier graphics are interactive. This page uses interactive examples, relying heavily on Bezier.js, as well as "real" maths (in LaTeX form) which is typeset using the most excellent MathJax library. This book is open source. So far so good.
