Props

Component props

The props you'll use most. The ShaderOrb reference lists all of them.

PropTypeDefaultDescription
state"idle" | "thinking" | "speaking""idle"The mood. Eases the parameters toward that preset.
sizenumber280Width and height in points.
paramsRecord<string, number>Parameter overrides by key, clamped to each range. See the shader params below.
colorsRecord<string, string>Hex colors by key. See the colors below.
volumes{ input?: number; output?: number }Levels from 0 to 1 that the shader reads as input and output loudness.
interactivebooleanfalseTap pulses the orb; holding makes it swell.
quality"auto" | "low" | "medium" | "high" | number"auto"Render scale. Lower is cheaper and softer.
maxFpsnumber60Frame cap.
pausedbooleanfalseStops drawing and keeps the last frame.
onReady() => voidCalled once the first frame is on screen.
onError(error: Error) => voidCalled if the orb can't start. Without it the error is logged once.

Shader params

Pass these through params. Values are clamped to the range shown. integrated parameters are phase clocks: the shader accumulates them over time, so the value acts as a rate.

Moods

This orb ships presets for idle, speaking, thinking. Choosing a state eases the parameters toward that preset; anything you pass in params still wins.
