The simplest and possibly most common is the Google Cardboard style of VR which is basically a phone put into a $5 – $50 face mask. This kind of VR has no controller so people have to come up with creative solutions for allowing user input. The most common solution is “look to select” where… Continue reading VR – Look to Select

Enhancing Objects with a Custom Glow Shader in Three.js Shaders in Three.js allow for highly customizable visual effects, and one of the most striking effects is the “glow” or “neon” effect. The provided code defines a custom shader material that applies a glowing effect to an object in a Three.js scene. This article explores how… Continue reading Enhancing Objects with a Custom Glow Shader in Three.js

Performance optimization is critical when creating large-scale VR environments in Three.js. A well-optimized scene ensures smooth frame rates, reduced latency, and an overall better user experience. Key Performance Optimization Techniques 1. Level of Detail (LOD) Management Using LOD techniques, models with lower detail are displayed when objects are far away, reducing rendering overhead. This is… Continue reading Optimizing Three.js Performance for Large-Scale VR Worlds

Artificial Intelligence (AI) can add realism and engagement to virtual environments by enabling NPCs (non-player characters) to interact dynamically with users. In Three.js, AI-driven NPCs can be programmed for pathfinding, decision-making, and adaptive behaviors. Core AI Techniques for NPCs in Three.js 1. Pathfinding and Navigation Using libraries like Yuka.js, NPCs can navigate complex environments, follow… Continue reading AI-Powered NPCs in Three.js: Bringing Virtual Characters to Life

Creating engaging VR environments in Three.js requires more than just rendering 3D models. Implementing interactive elements like physics-based objects, UI elements, and environmental feedback can significantly enhance user immersion. Core Elements of Interactive VR Environments 1. Hand and Controller Interactions VR controllers allow users to interact with objects naturally. Using WebXR and Three.js, developers can… Continue reading Interactive VR Environments in Three.js: Enhancing User Experience

Physics simulation plays a crucial role in making 3D environments feel interactive and realistic. In Three.js, integrating physics engines like Cannon.js or Ammo.js allows developers to simulate gravity, collisions, and dynamic object interactions. This article explores techniques for implementing physics in Three.js, from rigid bodies to soft-body physics. Why Use Physics in Three.js? Realism: Adds… Continue reading Real-Time Physics in Three.js: Simulating Dynamic Interactions

Virtual Reality (VR) experiences in Three.js can be significantly enhanced by adding interactive UI elements. ThreeMeshUI is a powerful library that enables the creation of responsive, lightweight, and flexible 3D user interfaces in WebXR environments. In this article, we will explore how ThreeMeshUI is initialized and used to create interactive panels in a VR scene.… Continue reading Creating Interactive VR Panels with ThreeMeshUI in Three.js

This class can only be used in combination with WebGLRenderer.copyFramebufferToTexture(). const pixelRatio = window.devicePixelRatio; const textureSize = 128 * pixelRatio; // instantiate a framebuffer texture const frameTexture = new FramebufferTexture( textureSize, textureSize ); // calculate start position for copying part of the frame data const vector = new Vector2(); vector.x = ( window.innerWidth * pixelRatio /… Continue reading FramebufferTexture

Create a texture to apply to a surface or as a reflection or refraction map. Note: After the initial use of a texture, its dimensions, format, and type cannot be changed. Instead, call .dispose() on the texture and instantiate a new one. Code Example // load a texture, set wrap mode to repeat const texture =… Continue reading Texture
