AI Summary

This is a visual effects library for Three.js that creates the illusion of interior rooms inside a flat surface. Instead of building complex 3D room geometry, you place a simple plane that automatically renders as if it contains multiple rooms with walls, floors, and ceilings. Each surface can have its own color or texture, and you can control how deep the rooms appear and how much shadow fills them. It's useful for game developers or web creators who want stylized building exteriors without heavy 3D modeling work.

How It Works

1
🎨 You're designing a 3D scene

You're building a game or interactive visualization and want buildings to look like they have real rooms inside them.

2
🏠 You discover interior mapping

You find this tool that creates the illusion of depth inside a flat wall, making it look like it contains dozens of separate rooms.

3
✨ Everything looks customizable

You can set the color and texture for each wall separately: front, back, left, right, ceiling, and floor all get their own look.

4
📦 You add it to your project

You bring this component into your scene and watch a flat surface transform into a multi-room interior instantly.

5
🎛️ You adjust to your liking

During your work, you change the depth of the rooms, switch colors, add wood textures to floors, and adjust how dark the shadows appear.

🌟 Your scene comes to life

Your buildings now look like they have real depth inside them, impressing everyone who sees your project.

What is three-interior-plane?

This is an interior mapping shader implementation for Three.js. It creates fake 3D room interiors on a flat plane by raymarching through a virtual box, letting you see "inside" buildings without modeling actual geometry. You get full control over every surface--back wall, side walls, floor, ceiling, and even a front wall layer for windows or doorways. Colors and textures change at runtime through uniforms, so you can animate or interact with the interiors without rebuilding the scene.

Why is it gaining traction?

Interior mapping is a well-known trick from games like Spider-Man, and this brings it to the web. The hook is simplicity: one plane, one call, instant fake 3D depth. Unlike static texture mapping, every wall, floor, and ceiling gets individual control--solid colors or textures, enabled or disabled per surface. Shadow intensity scales with depth, giving rooms a natural feel without extra lights. It is the kind of effect that usually requires engine-specific plugins, but this is plain JavaScript with a readable shader.

Who should use this?

Web developers adding building facades or window views to Three.js scenes. Game developers prototyping city layouts where rooms are seen from outside. Anyone building an interior design app or portfolio site who wants stylized 3D without modeling dozens of unique rooms. Not suitable for photorealistic archviz--this is best for stylized, game-like interiors.

Verdict

The implementation is clean and the concept is solid, but with only 10 stars and a credibility score of 0.8%, this is early-stage and unproven. No tests, no examples beyond the README. Use it for learning, side projects, or experiments. For anything production-critical, wait until the project builds documentation and community trust.
