Building Realistic Terrain with Height Maps in Three.js

Overview Height maps in Three.js are grayscale images that define the elevation of terrain in a scene. By applying a height map to a plane geometry, you can generate realistic landscapes, including mountains, valleys, and other geographical features. Key Features: Realistic Terrain Generation: Use height maps to create detailed, natural-looking environments. Ease of Use: Height… Continue reading Building Realistic Terrain with Height Maps in Three.js

Introduction to Shader Materials: Customizing Visual Effects in Three.js

Overview Shader materials in Three.js allow developers to create custom visual effects by writing GLSL (OpenGL Shading Language) shaders. These shaders provide fine-grained control over how objects are rendered, enabling effects like water reflections, custom lighting, and non-photorealistic rendering. Key Features: Custom Visual Effects: Shaders enable unique visual styles and effects that are difficult to… Continue reading Introduction to Shader Materials: Customizing Visual Effects in Three.js

Introduction to Three-Mesh-BVH: Accelerating Raycasting in Three.js

Overview three-mesh-bvh is a powerful extension for Three.js that enhances the performance of raycasting and spatial queries by implementing a Bounding Volume Hierarchy (BVH) structure. BVH is a tree structure that efficiently partitions 3D space, allowing for faster intersection tests, which is particularly useful in complex scenes. Key Features: Raycasting Acceleration: Raycasting is essential in… Continue reading Introduction to Three-Mesh-BVH: Accelerating Raycasting in Three.js

Threejs Scene creation

Creating the scene To actually be able to display anything with three.js, we need three things: scene, camera and renderer, so that we can render the scene with camera. main.js — import * as THREE from ‘three’; const scene = new THREE.Scene(); const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 ); const… Continue reading Threejs Scene creation

Threejs-Lines

Drawing lines Let’s say you want to draw a line or a circle, not a wireframe Mesh. First we need to set up the renderer, scene and camera (see the Creating a scene page). Here is the code that we will use: const renderer = new THREE.WebGLRenderer(); renderer.setSize( window.innerWidth, window.innerHeight ); document.body.appendChild( renderer.domElement ); const camera = new THREE.PerspectiveCamera(… Continue reading Threejs-Lines
