Three.js

What This Skill Does

The Three.js OpenClaw skill provides a comprehensive framework for building high-performance 3D web experiences. It serves as a specialized assistant that enforces industry-standard patterns, preventing common memory leaks and rendering issues associated with the WebGL API. By automating the boilerplate for resource management, camera configurations, and render loops, it ensures that your 3D scenes remain performant across various devices and browsers.

Installation

To integrate this skill into your development workflow, use the OpenClaw CLI: clawhub install openclaw/skills/skills/ivangdavila/threejs

Use Cases

This skill is ideal for developers building interactive product showcases, web-based games, data visualizations, and immersive architectural walk-throughs. It is particularly useful when migrating legacy Three.js codebases to more modern, performant standards, or when managing complex scenes that require optimized memory disposal and draw-call reduction.

Example Prompts

1. "OpenClaw, check my Three.js scene for memory leaks; I'm seeing performance degradation after navigating between different 3D views."
2. "Help me optimize my render loop using setAnimationLoop and explain how to correctly dispose of textures when I swap out a GLTF model."
3. "I have 500 identical trees in my scene causing lag. How do I switch these to InstancedMesh and what is the best way to handle their frustum culling?"

Tips & Limitations

To ensure peak performance, always prioritize BufferGeometryUtils for merging static meshes to minimize draw calls. Be mindful that renderer.setPixelRatio should never exceed 2; higher values drastically impact GPU memory without noticeable visual quality gains. Always remember that Three.js does not automatically garbage collect GPU-resident objects. Every Texture, Material, and Geometry must be explicitly disposed of using .dispose() before removal. Note that this skill primarily acts as a guide and optimization advisor; while it provides code patterns, it cannot magically fix architecture that is inherently incompatible with WebGL standards, such as improper asset loading across cross-origin boundaries.
