Three.js Post-Processing: BokehPass and SSAOPass Guide

Many web developers can build basic 3D scenes, but giving them a cinematic, realistic feel requires advanced rendering techniques. Post-processing allows you to apply professional visual effects directly to your canvas. In this text-based course, you will learn how to elevate your Three.js projects by implementing two powerful post-processing effects: BokehPass for realistic depth of field and SSAOPass for screen-space ambient occlusion. What you'll learn: Understand the fundamentals of the Three.js EffectComposer and post-processing pipelines; Configure BokehPass to simulate realistic camera lens focus and blur effects; Apply SSAOPass to create soft, realistic shadows in corners and crevices; Implement modern ES module imports to keep your 3D codebase clean and modular; Optimize rendering performance by properly managing and disposing of post-processing passes. You will start with foundational concepts of shaders and render passes before moving into step-by-step code implementations for both depth of field and ambient occlusion. This course is designed for beginners with a basic grasp of Three.js who want to master post-processing, requiring no advanced math or shader programming experience. Start reading today to bring cinematic realism to your web-based 3D scenes.
