This project creates a 3D WebGL-based visualization system for real-time visitor monitoring with in an exhibition complex. The primary technology stack includes Three.js for 3D rendering, ECharts for 2D charting, and WebSocket for live data transmission. The system displays visitor density, demographic analytics, and flow patterns across differ ...

Core Setup Before implementing ainmations, initialize the essential Three.js components: a scene, perspective camera, WebGL renderer, a yellow cube mesh, and an axis helper for spatial reference. import * as THREE from 'three'; const scene = new THREE.Scene(); const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.inne ...

Urban fire safety, particularly in high-rise environments, requires sophisticated monitoring and evacuation planning. A 3D simulation provides an intuitive interface for fire positioning, equipment tracking, and emergency drills. Using WebGL and Three.js allows developers to create these complex environments that run directly in the browser wit ...

Building Visualization Techniques For effective 3D building vsiualization, proper model segmentation is crucial. Key components should be separated: 1. Floor Separation Implementation class BuildingManager { constructor() { this.floorState = 'closed'; this.floorCache = {}; } toggleFloors(buildingId, callback) { const building ...

Shadow rendering in Three.js relies on a specific pipeline involving the renderer, light source, geometry, and material configurations. By default, the engine skips shadow calculations to presreve performance. To activate this feature, four distinct components must be properly configured. First, enable the shadow mapping system on the renderer ...

3D Coordinate System Visualization Visualizing Coordinate Axes THREE.AxesHelper() accepts a parameter that determines the length of the coordinate axis lines. You can adjust this value based on your scene requirements. // AxesHelper: Visual reference for 3D axes const axisIndicator = new THREE.AxesHelper(200); scene.add(axisIndicator); Imple ...

Introduction In the previous article, we explored the overall design concept and discussed the visual presentation and user experience of a modern tech website. Since the initial internal design leaned toward minimalism, the team began exploring ways to enhance the overall design aesthetic. This article delves into the implementation details of ...

Proxy Interference with Three.js Rendering When using Vue 3's reactive() to wrap Three.js objects like scene, camera, renderer, and controls, a runtime error occurs during rendering: three.module.js:24471 Uncaught TypeError: 'get' on proxy: property 'modelViewMatrix' is a read-only and non-configurable data property on the proxy target but th ...

Texture Fundamentals Texture mapping in Three.js utilizes THREE.MeshBasicMaterial and THREE.TextureLoader. The basic materail renders objects without lighting influence, allowing direct color assignment or image application to surfaces. The texture loader facilitates loading of image assets for use as textures. Before proceeding, set up the ess ...
