WebGPU Three.js with TSL

TSL (Three.js Shading Language) is a node-based shader abstraction that lets you write GPU shaders in JavaScript instead of GLSL/WGSL strings.

Quick Start

import * as THREE from 'three/webgpu';
import { color, time, oscSine } from 'three/tsl';

const renderer = new THREE.WebGPURenderer();
await renderer.init();

const material = new THREE.MeshStandardNodeMaterial();
material.colorNode = color(0xff0000).mul(oscSine(time));

Key Concepts

Import Pattern

// Always use the WebGPU entry point
import * as THREE from 'three/webgpu';
import { /* TSL functions */ } from 'three/tsl';

Node Materials

Replace standard material properties with TSL nodes:

material.colorNode = texture(map);        // instead of material.map
material.roughnessNode = float(0.5);      // instead of material.roughness
material.positionNode = displaced;         // vertex displacement
