How to build a cinematic 3D landing page from a brief with Dioramas

Turn a one-page brief into a scroll-driven 3D product site using the Dioramas engine.

Who it is forA front-end developer or designer who needs a visually striking 3D landing page for a single product and has a short creative brief.

The problemBuilding a cinematic scroll-driven 3D page from scratch means wiring lighting, camera moves, post effects and scroll timing by hand.

The outcomeA working local 3D landing page that follows the same structure as the 20 example sites, with one signature interaction.

What you need first

  • Git and Node.js with npm, to clone the repo and run the dev server
  • A desktop GPU, which the README recommends for 60 fps
  • About 330 MB of disk space for the repo, since models ship in the clone (no LFS)
  • A fal account and FAL_KEY, only if you want to generate new models or images

Steps

  1. Run git clone https://github.com/blendi-remade/dioramas && cd dioramas
  2. Run npm install
  3. Run npm run dev and open http://127.0.0.1:5190 to browse the gallery and the example sites.
  4. Write a one-page brief for your product, following the examples in docs/briefs/.
  5. Give the brief and docs/ENGINE.md to your coding agent and ask it to build the page in examples/ using the engine in src/core/.

Prompt for your agent

Work in the blendi-remade/dioramas repo. Read docs/ENGINE.md and the brief at <path-to-brief>, then build a new example site under examples/ for <product name> with one signature interaction. Expected output: an examples/<slug>/ folder with index.html, main.js and style.css that loads at /examples/<slug>/ on the dev server. Verify by running npm run dev and confirming the new page renders without console errors.

Caveat. The README says the examples were built by an AI coding agent against the engine, but it does not name a specific agent, and the models ship in the repo, so you still need to check the result on a desktop GPU.
