What is NixieFX?

What NixieFX does
The platform enables authors to design particle effects in an editor and integrate them into PixiJS or Three.js games. It provides an editor manual covering emitter modules, curves, gradients, the timeline, materials, preview backends, and export bundles. For Three.js, it includes ThreeVfxRenderer, effect-instance APIs, runtime controls, providers, and stats. It also includes the nixie-fx command line to create effects, validate projects, and export game bundles within agent and CI workflows.
Who NixieFX is for
It is built for teams authoring HTML5 web games in Three.js or PixiJS, mobile gamedev projects, and coding agents.
