Fluid Distortion for React Three Fiber

Implementing post-processing fluid distortion effects in response to cursor interactions for React-Three-Fiber. Based on the shaders developed by Pavel Dobryakov

Try it :

codesandbox

Installation :

npm install @whatisjery/react-fluid-distortion @react-three/drei @react-three/postprocessing postprocessing leva

Example of use :

import { Fluid } from '@/whatisjery/react-fluid-distortion';
import { EffectComposer } from '@react-three/postprocessing';
import { Canvas } from '@react-three/fiber';

<Canvas
    style={{
        position: 'fixed',
        top: 0,
        left: 0,
        height: '100vh',
        width: '100vw',
        background: '#000000',
    }}>
    <EffectComposer>
        <Fluid />
        {... other effets}
    </EffectComposer>
</Canvas>;

Options :

Name	Type	Default Value	Description
fluidColor	hexadecimal	#005eff	Sets the fluid color. Effective only when rainbow is set to false.
backgroundColor	string	#070410	Sets the background color. Effective only when showBackground is true.
showBackground	boolean	false	Toggles the background color's visibility. If false it becomes transprent.
blend	number	5	Blends fluid into the scene when showBackground is true. Valid range: 0.00 to 10.0.
intensity	number	10	Sets the fluid intensity. Valid range: 0 to 10.
force	number	2	Multiplies the mouse velocity to increase fluid splatter. Valid range: 0.0 to 20.
distortion	number	2	Sets the distortion amount. Valid range: 0.00 to 2.00.
radius	number	0.3	Sets the fluid radius. Valid range: 0.01 to 1.00.
curl	number	10	Sets the amount of the curl effect. Valid range: 0.0 to 50.
swirl	number	20	Sets the amount of the swirling effect. Valid range: 0 to 20.
velocityDissipation	number	0.99	Reduces the fluid velocity over time. Valid range: 0.00 to 1.00.
densitionDissipation	number	0.95	Reduces the fluid density over time. Valid range: 0.00 to 1.00.
pressure	number	0.80	Controls the reduction of pressure. Valid range: 0.00 to 1.00.
rainbow	boolean	true	Activates color mode based on mouse direction. No range applicable as this is a boolean value.
