What it does
Design rich, eye-catching 3D particle systems and effects for any JavaScript application on Windows, Mac or Linux — with Nebula.
A WebGL & WebGPU 3D particle system engine for three.js.
Choose from a wide variety of particle initializers & behaviors to create truly expressive, dynamic particle systems from textures or 3D objects. Load your entire system from a JSON object which you can easily share with others or modify for a fast and user friendly development experience. Render tens of thousands of particles at a buttery 60fps with the dedicated WebGL & WebGPU renderer — built for scale without dropping frames. Nebula has been a desktop editor for Windows, Mac and Linux, letting you design three-nebula particle systems visually — no code required. Now it's coming to the web: the same intuitive interface, running right in your browser, with your creations exported asfrom three-nebula.org
