EdgeSplitModifier is intended to modify the geometry “dissolving” the edges to give a smoother look. Import EdgeSplitModifier is an add-on, and therefore must be imported explicitly. See Installation / Addons. import { EdgeSplitModifier } from ‘three/addons/modifiers/EdgeSplitModifier.js’; Code Example const geometry = new THREE.IcosahedronGeometry( 10, 3 ); const modifier = new EdgeSplitModifier(); const cutOffAngle = 0.5; const… Continue reading EdgeSplitModifier

Why Unreal Engine is Often Considered Superior to Three.js
Unreal Engine (UE) and Three.js are powerful tools for creating 3D experiences, but they cater to different needs. While Unreal Engine is a comprehensive game engine, Three.js is a lightweight JavaScript library for 3D rendering on the web. Below, we compare the two across various dimensions to help you understand why Unreal Engine is often… Continue reading Why Unreal Engine is Often Considered Superior to Three.js
Understanding Logarithmic Depth Buffer in Three.js
In 3D graphics, one of the most common challenges encountered during rendering is depth precision. As scenes grow in size, especially in large open-world games or simulations, objects that are far away from the camera can suffer from depth precision issues, leading to z-fighting, where surfaces appear to flicker or overlap incorrectly. This is due… Continue reading Understanding Logarithmic Depth Buffer in Three.js
Understanding Light Probes in Three.js
Lighting plays a critical role in creating realistic 3D scenes. In Three.js, light probes are a powerful tool for capturing and utilizing ambient light from the surrounding environment to enhance the realism of your scene. This article delves into what light probes are, how they work, and how you can use them effectively in Three.js.… Continue reading Understanding Light Probes in Three.js
Customizing Instanced Mesh Attributes in Three.js
Instanced meshes in Three.js allow you to efficiently render multiple copies of a geometry with shared material properties, reducing draw calls and improving performance. However, real-world applications often require each instance to have unique attributes, such as different colors or material properties. This article will guide you through customizing instanced meshes with per-instance attributes. 1.… Continue reading Customizing Instanced Mesh Attributes in Three.js
