SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Landing pages and hero sections often need an atmospheric, immersive background that adds depth without competing with foreground content. This Skill provides a repeatable recipe for building a perspective WebGL tech grid that recedes into space with subtle motion, so designers and developers avoid ad-hoc shader experiments and inconsistent results.

Core Features & Use Cases

  • Perspective Grid Rendering: Build a large ground-plane grid viewed from an elevated camera, with line opacity fading by distance so the far field dissolves smoothly.
  • Ambient Motion System: Add slow forward drift, a sparse additive particle field, and damped mouse-responsive camera parallax for calm, living depth.
  • Tuning Controls: Adjust grid density, fade falloff, drift speed, camera height and tilt, and restrained accent-color glow to match any design system.
  • Use Case: A designer building a dark SaaS hero section uses this Skill to generate a Three.js background grid that sits behind the headline, stays understated, and remains responsive and reduced-motion friendly.

Quick Start

Use the background-grid-webgl skill to add a subtle perspective WebGL grid background with drifting particles and gentle parallax behind my landing page hero.

FAQPage Schema
How do I create a perspective WebGL grid background for a landing page?

Use Three.js with a perspective camera positioned above a large ground-plane grid, looking toward the origin. Fade line opacity by distance so the grid dissolves toward the horizon, then add slow forward drift and a sparse particle field for depth.

What library should I use for a WebGL grid background effect?

Three.js is the recommended choice for this effect because it provides perspective cameras, grid helpers, and particle systems out of the box. Any equivalent real WebGL rendering approach also works if it supports camera control and line opacity fading.

Can I add mouse parallax to a WebGL background without making it distracting?

Yes, apply damped camera parallax by lerping the camera offset toward the mouse position with a small smoothing factor. Keep the movement amplitude low so the background feels alive but stable behind foreground content.

When should I avoid a neon grid background style?

Avoid bright synthwave neon grids unless the design explicitly calls for that retro style. Thick lines, high contrast, dense particles, or fast motion compete with foreground content and make the background feel unstable.

How do I keep a WebGL background performant and accessible?

Cap device pixel ratio, keep particle counts low, and use slow drift speeds. Respect reduced-motion preferences by disabling drift and parallax, and ensure the canvas sits behind content with pointer-events disabled.
