Shaft Light

Install

Or by hand, in a Next.js project with shadcn set up. It writes components/pastetaste/shaft-light.tsx.

Install the pastetaste component "Shaft Light" (shaft-light) into this Next.js project and use it.

What it is: Volumetric light rays falling from a source above the top edge, with drifting dust and a cone that sways and leans toward the pointer. One WebGL shader.

Before you place it, ask me (one short message, in my language; "skip" = sensible default): which page and section it goes in, my brand colour (hex), the text, labels or images it should show, and whether I want my logo or my own copy in the demo content. Then:

Steps:
1. If the project has no components.json, run: npx shadcn@latest init -y -d. Then run: npx shadcn@latest add https://pastetaste.com/r/shaft-light.json
   (it writes components/pastetaste/shaft-light.tsx; install any npm packages it reports).
2. Import it: import { ShaftLight } from "@/components/pastetaste/shaft-light" (check the file for the exact named export).
3. Put it where it fits on the page I name, keep the rest of the page untouched, and pass props for my colours instead of editing the installed file.
4. It does not depend on Tailwind; colours come from CSS variables (--pt-*) or props.
5. It uses WebGL: render it in a client component and give it a fixed-height parent; it pauses off-screen and shows a still frame for reduced motion.

Props (all optional unless the type has no default):
- near: string = '#fff0c4' — Colour of the light near the source.
- far: string = '#e0883a' — Colour of the light as it fades out.
- background: string = '#0b0907' — Ground colour the light is added to.
- origin: number = 0.5 — Horizontal position of the source, 0 left to 1 right.
- spread: number = 34 — Half-angle of the cone in degrees.
- rays: number = 9 — How many separate rays fit in the cone.
- reach: number = 0.85 — How far the light reaches down, as a share of the height.
- intensity: number = 1 — Brightness multiplier.
- speed: number = 1 — Drift speed; 0 freezes the rays.
- followPointer: boolean = true — The cone leans toward the pointer while it moves over the page.
- quality: number = 0.7 — Render scale against CSS pixels.
