Three.js 3D Geometries: Working with Cylinders and Cones

Want to move beyond basic cubes and spheres in your web graphics? Learning how to manipulate cylindrical and conical shapes is essential for rendering realistic 3D objects like pillars, trees, pipes, and custom interactive elements. This text-based course guides you through the core properties and applications of CylinderGeometry and ConeGeometry in Three.js. You will learn to construct, style, and optimize these foundational 3D shapes, turning static code into dynamic, interactive web scenes. What you'll learn: Understand the mathematical anatomy of cylinders and cones in 3D space; Configure radius, height, and segment parameters to balance visual quality and performance; Apply modern ES modules and clean JavaScript structure to your Three.js projects; Create open-ended structures and partial shapes using theta start and length properties; Implement materials and basic lighting to bring your geometries to life; Practice responsive canvas sizing and proper resource disposal for optimal performance. You will start with the fundamental terminology of WebGL coordinates and geometry vertices before diving into practical code examples. Through clear, written explanations and structured code snippets, you will build and customize various cylindrical and conical models from scratch. This course is designed for beginner front-end developers and web designers with basic HTML and JavaScript knowledge. No prior 3D modeling experience is required.
