WebGL Gravity Particle Swarm - WebGL 3D GPU WebGL background for React & Tailwind
Integrate the WebGL Gravity Particle Swarm directly into your website. This asset is rendered using raw WebGL shader context. It is optimized for zero layout-shifts and runs with high-performance hardware-accelerated processing.
⚡ Performance Specifications
- Render Mode: WEBGL (WebGL 3D GPU)
- Fluidity: Locked at 60fps dynamic loop
- Bundle Footprint: Zero external NPM dependencies
- SEO Indexing status: 100% Crawlable static semantic HTML
🛠️ Integration Capabilities
Our templates expose inline design tokens like --color-1 and --color-2 for infinite color palettes. This template is designed to fit inside hero elements, full-screen landing pages, and interactive presentation cards.
