[linbingquan]

Description

checker.coord has default value, but it can't work.

three.js/src/nodes/procedural/Checker.js

Lines 12 to 22 in e3ee968

	export const checker = /*@__PURE__*/ Fn( ( [ coord = uv() ] ) => {
	const uv = coord.mul( 2.0 );
	const cx = uv.x.floor();
	const cy = uv.y.floor();
	const result = cx.add( cy ).mod( 2.0 );
	return result.sign();
	} );

None

Code

import { checker, uv } from 'three/tsl';
import { BoxGeometry, Mesh, MeshBasicNodeMaterial, PerspectiveCamera, Scene, WebGPURenderer } from 'three/webgpu';

const scene = new Scene();
const aspect = window.innerWidth / window.innerHeight;
const camera = new PerspectiveCamera(50, aspect);
camera.position.z = 5;
const renderer = new WebGPURenderer({ antialias: true, alpha: true });
renderer.setPixelRatio(window.devicePixelRatio);
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

const geometry = new BoxGeometry();
const material = new MeshBasicNodeMaterial();

material.colorNode = checker(); // it can not work
// material.colorNode = checker(uv()); // it can work

const mesh = new Mesh(geometry, material);
scene.add(mesh);

renderer.render(scene, camera)
