Three.js pixel art diorama scenes and QA workflows

Build pixel art diorama scenes in Three.js featuring locked orthographic cameras, color palette snapping, ordered dithering, and ink outlines using the Diorama playbook and code suite. Ensure visual fidelity and verifiable screenshots and animations through deterministic pure-function scene design and per-entity frame QA.

Key points

Adopt a research-first build workflow: fill out the DESIGN.md design sheet and SOURCES.md research log before modeling.
Maintain the visual contract: use a locked three-quarter perspective camera, flat silhouettes on a white background, a 64-color palette, ordered dithering, and ink outlines.
Ensure total scene determinism: the scene must be a pure function of time t so that any frame can be frozen, screenshotted, and compared.
Execute per-entity frame QA: use QA scripts and tools in the verify/ directory to validate the build output and ensure screenshots serve as definitive proof.
Copy modules as needed: copy required modules from templates/ into your project instead of editing installed copies directly.

.cursorrules

- Follow the research-first build workflow, completing research and design sheets prior to modeling.
- Keep scenes deterministic as pure functions of time t to facilitate frame freezing and QA screenshot comparison.
- Use fixed specifications: a locked three-quarter camera, 64-color palette, ordered dithering, and ink outlines.
- Assemble components using modules from templates/ rather than writing non-compliant code from scratch.

Copy-ready prompt

Please build a pixel art diorama scene for me following the Diorama playbook specifications. Use Three.js and implement a locked three-quarter camera, 64-color palette snapping, ordered dithering, and ink outlines. The scene must be a pure function of time t to ensure determinism. First research and fill out DESIGN.md, then build the scene through a deterministic animation pipeline, and finally run the QA scripts for validation. The theme is: [Enter scene theme here, e.g.: pool / night market / bank job / arena battle].

Build high-quality 3D websites quickly with Claude

Generate working Three.js scenes in a single pass using refined prompts that strictly filter out useless output with Claude Code. The core technique is fast filtering rather than blindly generating numerous random versions, cutting a week of development down to a single afternoon.

Pitfalls and best practices for building 3D simulation frontends with AI

The author used AI (Opus) along with Three.js to build a 3D simulation frontend for the Singapore MRT. By reusing existing structured data, using artifacts for early visual decisions, and iterating on HUD design, you can significantly boost AI-driven frontend development efficiency.

Collaborative 3D browser game development with AI

While recovering from illness, the author built the browser-based off-road racing game Slipface using Claude Code. By writing documentation, defining skills, providing reproduction links, and describing game feel, they achieved high-quality AI frontend and game development collaboration.
