Background Grid WebGL Skill

Use When

Create a perspective WebGL background grid with fading lines, subtle particle haze, slow forward drift, and gentle camera parallax.

Apply this only to the immersive background grid layer, not to the full page layout, copy, or unrelated particle or laser systems.
Use it when the design needs a perspective tech grid receding into space with subtle motion and depth.

Create a large perspective ground-plane grid viewed from an elevated camera angle so the lines recede toward the horizon.
Keep the grid understated and atmospheric: thin lines, soft fade with distance, dark background, and restrained glow rather than a loud retro neon floor.
Add a light field of floating particles or dust to give the scene depth without overpowering the grid.
Use the design's primary color or strongest accent color sparingly for glow, particles, or secondary emphasis. If the design is neutral, a white or cool gray grid is acceptable.

Prefer Three.js or equivalent real WebGL rendering for this effect.
Use a perspective camera positioned above the plane and looking toward the origin to emphasize depth.
Build the grid as a large plane helper or custom grid with line opacity fading by distance so the far field dissolves smoothly.
Animate the grid with slow forward drift or repeated positional cycling so it feels alive without becoming distracting.
Add subtle mouse-responsive camera parallax or offset, but keep the movement calm and damped.
Add a sparse additive particle field with low opacity and slow motion to soften the empty space around the grid.

Grid density: control plane size, division count, and line spacing.
Fade: adjust opacity falloff so the grid recedes naturally into darkness.
Motion: tune forward drift speed, particle float speed, and camera smoothing.
Camera: adjust height, distance, tilt, and parallax strength to control perspective drama.
Color: keep the base grid subtle and use the active design accent only as a restrained highlight.

Bright synthwave neon grids unless the design explicitly calls for that style.
Thick linework or high-contrast grids that compete with foreground content.
Dense particles or fog that obscure the grid structure.
Aggressive mouse tracking or fast grid motion that makes the background feel unstable.
