threejs-geometry
Lets your agent create 3D shapes. It can make ready-made shapes or build custom ones from scratch, optimizing performance.
What it does
This tool helps create 3D shapes using the Three.js library. It can generate ready-made basic shapes or more complex shapes you describe.
When to use it
- ✓When you want to create a simple 3D object, like a cube or sphere.
- ✓When you need a custom 3D shape that doesn't exist ready-made.
- ✓When you want to make many copies of the same object efficiently.
Example of what to ask your AI
“Create a sphere with radius 5 and 100 segments.”

How it works
You describe the shape you want, and the tool uses the functions of the Three.js library to build the points and lines that form that shape in 3D space.
Installation
Easiest way: copy the skill link and paste it into Claude, ChatGPT or Cursor asking it to follow the instructions.

Three.js Geometry
Detailed Guide
Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.
When to Use
- You need to create or optimize geometry in Three.js.
- The task involves built-in shapes, custom
BufferGeometry, vertices, or instanced rendering. - You are working on mesh structure rather than scene setup or materials alone.
Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
FAQ
What is Three.js?
Three.js is a popular library that makes it easy to create 3D graphics in web browsers.
What is 'BufferGeometry'?
It's an advanced way to define geometries (shapes) in Three.js, allowing for more control and optimization.
What is 'instanced rendering'?
It's a technique for drawing many copies of the same object very quickly and efficiently, saving resources.
