ORB-21

Light diffusing through a cloud

Installation


$ pnpm dlx shadcn@latest add @shadercn/orb-21

import { Orb21 } from "@/components/orbs/orb-21";

<Orb21 size={280} state="idle" />

Prop	Type	Default	Description
`state`	`"idle" \| "thinking" \| "speaking"`	`"idle"`	Drive preset the orb eases toward
`size`	`number`	`280`	Rendered size in CSS pixels
`params`	`Partial<Record<string, number>>`	-	Shader param overrides, see Shader Props
`colors`	`Partial<Record<string, string>>`	-	Shader colour overrides as hex strings
`statePresets`	`Partial<Record<OrbState, Record<string, number>>>`	-	Replace the built-in per-state param presets
`stateColors`	`Partial<Record<OrbState, Record<string, string>>>`	-	Replace the built-in per-state colours
`stateVolumes`	`Partial<Record<OrbState, { input?: number; output?: number }>>`	-	Pin the drive volumes a state settles on
`volumes`	`{ input?: number; output?: number }`	-	Drive the orb directly, bypassing synthesis
`paused`	`boolean`	`false`	Freeze the frame loop
`pauseOffscreen`	`boolean`	`true`	Stop rendering while scrolled out of view
`maxDpr`	`number`	`2`	Upper bound on the device pixel ratio
`className`	`string`	-	Class on the wrapper element
`style`	`CSSProperties`	-	Inline style on the wrapper element
`ariaLabel`	`string`	-	Accessible name for the canvas

Pass any of these through params; each is a single f32 uniform read by the shader.
