Seijaku: Interactive Three.js 3D Walkthrough of a Kyoto Residence

RepositoryMengTo/seijakuDemo

Seijaku is an interactive web demo by Meng To that delivers a continuous, scroll-based walkthrough of a virtual Kyoto residence. It combines procedural Three.js architecture, Web Audio soundscapes, and interactive material studies without requiring a build step.

Key points

  1. Continuous scroll-driven camera choreography through gardens, tea rooms, and courtyards with a free-orbit inspection mode.
  2. Interactive features including interactive floor-plan navigation, seasonal environment toggles, and Web Audio synthesis.
  3. Built with Three.js 0.176.0 and meshoptimizer 1.2.0 using instancing, procedural textures, reflections, and post-processing.
  4. Performance strategies include batched construction, staged texture uploads, shader pipeline pre-warming, and lazy-loaded assets.
  5. Zero-build static setup requiring no package manager or backend; HTML, CSS, shaders, and application code reside in index.html.

Why it matters

The project serves as an advanced benchmark for 3D storytelling and architectural landing pages on the web. It demonstrates how to integrate heavy WebGL scenes smoothly into editorial layouts using clever pipeline warming and lazy-loading strategies without relying on complex build toolchains.

Analysis

Seijaku addresses the challenge of merging high-fidelity 3D visualization seamlessly with editorial web design. Creator Meng To achieves this using Three.js 0.176.0 alongside meshoptimizer 1.2.0, blending runtime procedural geometry with compressed models, responsive WebP photos, and Web Audio. The target audience includes frontend engineers, creative coders, and 3D web designers looking for real-world patterns in WebGL choreography and performance tuning. In terms of maturity, it is a design concept and technical demo: the inquiry form is purely mock-driven without a backend, the code is consolidated into a single index.html file, and the repository currently lacks a formal open-source license.
