Use this file to discover all available pages before exploring further.

Dream Car has no dependencies to install, no build pipeline to configure, and no local server to start. The entire simulator — 3D engine, scene logic, UI, and music player — is contained in a single index.html file. As long as you have a modern browser and an internet connection, you can go from zero to driving in under a minute.
1

Download index.html

Go to https://github.com/JustADev1024/threejs-car and open the index.html file. On that page, click the Download raw file button (the downward-arrow icon near the top-right of the file viewer) to save the file to your computer. No ZIP extraction or repository cloning required — this single file is the entire application.
2

Open in your browser

Double-click the downloaded index.html file, or drag it directly into an open browser window. The Three.js engine and OrbitControls are fetched from cdn.jsdelivr.net on first load, so an active internet connection is required. The music tracks also stream from soundhelix.com when playback is started. Once the page loads you will see the car on the road and the dark control panel at the bottom of the screen.

Explore the controls

A glass-morphism control panel is anchored to the bottom of the viewport. It contains everything you need to customise the experience:
  • Time slider (0–24h) — drag to move the sun or moon across the sky and shift the scene between bright daylight and deep night.
  • Headlights button — toggle the car’s front SpotLight and PointLight on or off.
  • Exhaust button — toggle the animated particle cloud emitted from the exhaust pipe.
  • Track dropdown + Play — choose one of the sixteen built-in SoundHelix tracks from the dropdown, then press Play to start streaming. Press Stop to pause.
  • Custom MP3 URL field + Add — paste any direct .mp3 link into the input field and click Add to append it to the track list.

Technologies Used

Dream Car is built on a deliberately minimal stack — no framework, no bundler, no package manager:
  • Three.js 0.128.0 — handles all 3D rendering: scene graph, geometries, materials, lights, shadows, and the WebGLRenderer.
  • OrbitControls — provides mouse and touch-based camera rotation, panning, and zoom with inertia damping enabled.
  • HTML/CSS — the control panel uses a dark glass-morphism aesthetic (backdrop-filter: blur(12px), semi-transparent rgba(0,0,0,0.7) background, and a subtle rgba(255,255,255,0.2) border) with no external CSS framework.
  • JavaScript ES modules — all scene construction, animation, UI event handling, and audio management live in a single <script type="module"> block.
Both Three.js and OrbitControls are loaded via a native importmap in the file — no local copies needed:
index.html
<script type="importmap">
{
    "imports": {
        "three": "https://cdn.jsdelivr.net/npm/three@0.128.0/build/three.module.js",
        "three/addons/": "https://cdn.jsdelivr.net/npm/three@0.128.0/examples/jsm/"
    }
}
</script>
Because Three.js, OrbitControls, and all music tracks are loaded from public CDNs, there is no need to run a local development server or install any tooling. Simply open the file in a browser. The only hard requirement is an active internet connection — without it, the CDN assets will fail to load and the scene will not render.
Dream Car ships with a bilingual interface. The control panel defaults to English, but you can switch to Russian at any time by clicking the RU button in the Language row at the top of the panel. Click EN to switch back. All button labels, placeholders, and alert messages update instantly when you change the language.
