Three.js添加纹理可获得1像素的完整对象颜色

var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);

var geometry = new THREE.BoxGeometry(1, 1, 1);

var material = new THREE.MeshBasicMaterial({ color: 0xff0000 });

var cube = new THREE.Mesh(geometry, material);

scene.add(cube);

var renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

function animate() {
    requestAnimationFrame(animate);
    // 动画代码
    renderer.render(scene, camera);
}
animate();

var texture = new THREE.TextureLoader().load('texture.jpg');

var material = new THREE.MeshBasicMaterial({ map: texture });
