This tutorial demonstrates how to build a 3D city model in Three.js by adding ambient and directional lighting with shadows, generating random building geometries, customizing shaders for top‑view UV mapping, and implementing animated radar diffusion and scanning effects through shader uniform updates.
This article provides a step‑by‑step guide on using three.js—including installing the library, creating a scene with an orthographic camera, loading GLTF models, implementing touch‑based rotation, zoom, and pan interactions, adding lighting and rendering optimizations, and handling iOS Safari scaling issues.
The Alibaba Taobao Live and Canon guide offers a low‑cost, standardized solution for high‑quality e‑commerce live streaming, detailing a 20,000 CNY single‑camera seated‑broadcast setup—including equipment selection, room décor, a six‑step rapid installation, optimal camera/audio configurations, and software tips for TBS.
The article explains how AMap JSAPI 2.0 achieves realistic 3‑D building lighting by applying the Blinn‑Phong model with ambient, diffuse and specular components, employing directional, point and spot lights together with a classic three‑point lighting setup—including a high‑altitude point light over the Oriental Pearl Tower—to produce depth‑rich, non‑flat visualizations.
