Neural Background

A dynamic, shader-powered animated background with fluid neural-like visuals using OGL and GLSL.

API

Prop Name	Type	Default	Description
`hue`	`number`	`200`	Base hue for background colors (in degrees, 0–360).
`saturation`	`number`	`0.8`	Saturation of the background color (0–1).
`chroma`	`number`	`0.6`	Chroma/lightness factor of the HSL color (0-1).
`class`	`string`	`—`	Optional additional CSS classes for the canvas element.

💡 This component defaults to a full-screen fixed background with pointer-events-none. You can override styles via the class prop if needed.

GPU-accelerated animation: Powered by OGL, offering high-performance WebGL rendering.
Neural-inspired visuals: A recursive shader-based pattern that mimics brain-like structures and motion.
Live pointer interaction: Visuals react to cursor and touch movement in real time.
Scroll-driven dynamics: Color shift and brightness are subtly influenced by page scroll progress.
Customizable color palette: Modify hue, saturation, and chroma in real time with prop bindings.
Responsive: Auto-resizes to match viewport size and device pixel ratio.

Uses a custom fragment shader with recursive sine accumulation to generate a complex organic background.
Performance is optimized for modern browsers and GPUs; graceful degradation is not implemented for older environments.
Intended for decorative purposes (e.g., hero sections, full-screen backgrounds).
