Photorealistic rendering has long been a benchmark for high-quality graphics in 3D applications. Ray tracing and path tracing are at the forefront of this revolution, allowing developers to simulate realistic lighting, reflections, and refractions. With advances in WebGPU and GPU acceleration, Three.js now has the potential to achieve real-time ray tracing and path tracing in… Continue reading Real-Time Ray Tracing and Path Tracing in Three.js: A Guide to Photorealistic Rendering

Post-Processing Effects in Three.js
Post-processing in Three.js lets you add visual effects to enhance your scene. Using EffectComposer, you can stack multiple effects for a cinematic feel. Here’s a quick guide to popular effects: 1. Setup: Import EffectComposer, RenderPass, and effect passes: import { EffectComposer } from ‘three/examples/jsm/postprocessing/EffectComposer.js’; import { RenderPass } from ‘three/examples/jsm/postprocessing/RenderPass.js’; Initialize with: const composer =… Continue reading Post-Processing Effects in Three.js
Building Immersive Experiences with WebXR and Three.js
Creating VR and AR experiences on the web is easier than ever with WebXR and Three.js. WebXR allows access to VR and AR devices through the browser, while Three.js simplifies 3D graphics with easy-to-use functions for building interactive, immersive environments. 1. Set Up: Install Three.js, enable WebXR, and create a basic 3D scene. const scene… Continue reading Building Immersive Experiences with WebXR and Three.js
Guide to Using Custom Shaders in Three.js with GLSL
Custom shaders let you add unique effects to your scenes using GLSL (OpenGL Shading Language) in Three.js. Let’s create a basic shader that animates a wave effect. Step 1: Set Up Three.js Create a scene with a camera, renderer, and a mesh: import * as THREE from ‘three’; const renderer = new THREE.WebGLRenderer(); renderer.setSize(window.innerWidth, window.innerHeight);… Continue reading Guide to Using Custom Shaders in Three.js with GLSL
Optimizing Three.js for Performance: Techniques and Best Practices
Three.js makes it possible to create stunning 3D graphics on the web, but managing performance is essential to keep animations and interactions smooth. This guide covers some effective strategies for optimizing your Three.js projects. 1. Minimize Draw Calls Reducing draw calls (rendering instructions sent to the GPU) can significantly improve performance: Merge Geometries: Use BufferGeometry… Continue reading Optimizing Three.js for Performance: Techniques and Best Practices
A Quick Guide to Geometries in Three.js
Three.js offers a variety of geometries that allow developers to create complex 3D shapes easily. Here’s a brief overview of some specific geometries you can use in your projects: 1. ConvexGeometry ConvexGeometry is used to create a convex hull from a set of points. This is particularly useful for modeling objects that need to be… Continue reading A Quick Guide to Geometries in Three.js
An Introduction to EffectComposer in Three.js
EffectComposer is a powerful tool in Three.js that enables developers to apply post-processing effects to enhance the visual quality of 3D scenes. By rendering the scene to an intermediate texture, you can apply a series of shader effects called “passes” before displaying the final result. What is EffectComposer? EffectComposer allows for a more complex rendering… Continue reading An Introduction to EffectComposer in Three.js
A Guide to Exporters in Three.js
Exporters in Three.js allow you to save and share 3D models or scenes in various formats, making it easier to use them in other applications or reload them in new projects. Exporting is useful for sharing models, saving progress, or creating downloadable assets. Common Export Formats: GLTF/GLB: Modern format supporting complex scenes, animations, and textures.… Continue reading A Guide to Exporters in Three.js
Scene Switching in Three.js
In Three.js, switching between scenes involves managing multiple THREE.Scene objects and rendering one at a time based on user interaction or application logic. Below is a step-by-step guide on how to implement scene switching. 1. Creating Multiple Scenes You need to define multiple scene objects, each representing a different 3D environment. const scene1 = new… Continue reading Scene Switching in Three.js
