Claude Fable 5 prompt for an infinite Three.js paper machine

Build an infinite Three.js paper machine in a single prompt. Convert a static Pinterest concept into a functional 3D web app. The app should render a paper strip that rolls infinitely while continuously printing dynamic images onto its surface in real time.

Prompt optimization tips

1

Specify editability

State which objects must remain separate, named and editable; otherwise a visually convincing shell may still be unusable.

2

Close the test loop

Ask the model to run the scene, inspect visible failures and repeat until concrete frame-rate, interaction and layout checks pass.

3

Stage long builds

For large worlds, split the work into districts, assemblies or milestones and approve each section before expanding scope.

Imagine It. Shape It.
