If you’re tired of the same old static hero sections and want your personal site or blog to feel like it came straight out of a sci-fi movie, this is the definitive guide you’ve been looking for.
We’re going to build a fully interactive 3D Earth that:
- Spins smoothly with inertia
- Shows real terrain and 3D buildings in major cities
- Has glowing markers (light pillars, particles, animated billboards) for every blog post or project
- Lets visitors click a marker and be taken directly to the article
- Displays a custom info panel with post title, excerpt, tags, and date
- Works perfectly on desktop and mobile (with touch gestures)
- Loads fast and stays under ~2.5 MB even with all bells and whistles
This article is pure, copy-paste-ready production code used on real-world sites in 2025.
1. Why CesiumJS Is Still the King in 2025
| Feature | CesiumJS | Three.js + Globe.js / planetary.js | mapbox-gl + custom 3D | deck.gl |
|---|---|---|---|---|
| True WGS84 coordinates | Native | Manual math | 2.5D only | Yes |
| Global high-res terrain | Built-in Cesium World Terrain | Almost impossible | Limited | No |
| Photorealistic 3D Tiles cities | One-liner (Google/OSM buildings) | You build them | No | Partial |
| Time-dynamic data (CZML) | First-class | Not feasible | No | Yes |
| Mobile performance | 60 fps on iPhone 15 | Usually <30 fps | Good | Good |
| Bundle size (tree-shaken) | ~1.7–2.2 MB | ~800 KB–1.5 MB | ~1.3 MB | ~2 MB |
| Learning curve | Medium (but excellent docs) | Steep | Medium | Steep |
Bottom line: If you want a real planet, not a textured sphere, Cesium remains unmatched.
2. Project Setup – Zero Config (Vite + React / Vanilla / Next.js)
I’ll give you all three flavors. Pick your poison.
Vanilla (just one HTML file – perfect for static blogs)

import { Cartesian3, Color, Ion, ScreenSpaceEventHandler, ScreenSpaceEventType } from 'cesium';
import { useEffect, useRef } from 'react';

4. Performance Tips That Actually Matter in 2025
- Tree-shake Cesium → bundle size drops from 6 MB → ~1.7 MBJavaScript
import { Viewer, Entity, Ion } from 'cesium'; - Use Bing Maps Aerial with Labels Off or Sentinel-2 assetId: 3845 (most beautiful free layer)
- Enable globe.enableLighting = true + dynamicAtmosphereLighting = true – costs almost nothing, looks 10× better
- For huge blogs (>200 posts), cluster with CustomDataSource + EntityCluster
- Pre-warm the camera with viewer.camera.flyTo() on mount – prevents jank
