WebGL Lesson 9 (Perspective Matrices)

In Lesson 8 of this WebGL tutorial series, we learn how to create and use a perspective matrix in WebGL to render realistic 3D scenes. A perspective matrix is one of the most important concepts in 3D graphics. It allows objects that are farther away from the camera to appear smaller, creating the illusion of depth just like in the real world. In this lesson, we’ll break down how perspective projection works mathematically and apply it to our 3D cube. 🔹 What you'll learn in this video: • What a perspective matrix is • How perspective projection works in 3D graphics • Understanding field of view, near plane, and far plane • Building a perspective matrix step by step • Applying perspective transformations in WebGL By the end of this lesson, you’ll understand how cameras and depth work in computer graphics, giving your WebGL scenes a realistic 3D appearance. 📚 Part of the WebGL Tutorial Series This series is designed to take you from beginner to advanced in WebGL and graphics programming using JavaScript.
