Procedural Three.js 3D main menu background from an image

Majid Manzarpour shares a prompt for recreating an uploaded image as a fully procedural, animated Three.js 3D main-menu background in a single HTML file. The root post attributes the test to Opus 5.5.

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.
