3D simulation · History in motion

History in motion, on a 3D globe

Journeys and empires moving across a globe: the road that connected the world, trade routes and conquests. Not a drawing and not an AI guess: a simulation that runs the real numbers, narrated, with every moment landing on its word.

What the simulation shows

The real numbers it runs on

The simulation is built on these facts, so the narration and the picture always agree:

The script this video was made from

“The road that connected the world”: the narration of the video above. Each highlighted moment in the simulation happens on the word that names it.

In twelve seventy-one, a seventeen-year-old left Venice on a journey that would take twenty-four years.

The road east

Marco Polo travelled the Silk Road, across deserts and mountains, through Baghdad and Samarkand.

The great khan

He reached the court of Kublai Khan in China and stayed for seventeen years.

The book

His stories of the East amazed Europe, and inspired explorers for centuries.

Make your own

  1. Type a question, like “The road that connected the world”, or your own angle on it.
  2. ContentRoof picks this simulation, researches the facts and writes a short script, with every moment cued to a word.
  3. A natural voice reads it in your language and the simulation plays in time with it. Change any line and it follows.
  4. Download a vertical video for Shorts, TikTok and Reels, or use it in class.

Questions

Is this a real simulation or an AI-generated video?

A real simulation. History in motion runs on the numbers listed above, so what you see is what actually happens, frame by frame. AI video generators guess what a scene should look like; they often get the science wrong.

Can I change what the narrator says?

Yes. Type your own question or idea and the AI writes a new script for this simulation, or edit any line yourself. Every moment of the simulation lands on the word that names it.

Which languages can it narrate in?

Eleven: English, Urdu, Hindi, Arabic, Spanish, French, Portuguese, German, Italian, Russian and Polish, with captions written properly (Urdu in Nastaliq, Arabic right to left).

Can I use it in class or post it on YouTube?

Yes. The video is yours to use in lessons, on YouTube Shorts, TikTok and Instagram Reels. The free plan makes 2 3D simulations a month; paid plans make more, in 1080p without the small mark.
