WebGL Laser

Full-screen shader beam with white-hot core and brand-tinted fog.

What it is

A raw WebGL fragment shader drawing a thin vertical laser on a full-screen quad. Core stays near white; halo and FBM smoke follow your accent.

Create a fixed full-screen WebGL laser background effect with a thin white-hot vertical core, restrained brand-colored halo, and soft smoky fog around the beam. Use only for laser background effects, not full page layout
From the upstream SKILL.md

Why it matters for design

  • Halo and smoke read from your brand accent instead of a hardcoded blue.
  • Separate core and glow widths keep the beam a blade, not a bar.
  • Smoke concentrates near the beam and dissipates outward, protecting copy contrast.

What it covers

  • Scope
  • Visual target
  • Layering
  • Brand color
  • Raw WebGL setup
  • Tuning knobs

How to install

WebGL Laser

  1. Clone the repo.

    git clone https://github.com/MengTo/Skills
  2. Point Codex at the skill file.

    agent-skills/web-design/webgl-laser/SKILL.md
  3. Then describe the UI you want. Codex follows the skill.

How to run it with Codex

  1. Set a --brand-accent custom property, which the shader converts to RGB.

  2. Place the fixed canvas behind content with pointer-events none.

  3. Tune coreWidth, glowWidth, smokeDensity, and xOffset to position the beam.

Every plugin here is free, open source, and links to its real upstream source.
