[英]Three.js ply colorless (all black)
我正在尝试使用Three.js加载我的层文件。 它奏效了,但我几乎看不到任何颜色。 到处都有一些瞥见,但大部分都是黑色的(下面的第一张图片)。 图像在MeshLab中正确打开(带有颜色)(下面的第二个图像)。 我尝试了vertexColors: THREE.VertexColors
(如vertexColors: THREE.VertexColors
所建议-层文件-为什么无色? )和vertexColors: THREE.FaceColors
但似乎无济于事。 我是three.js新手,所以请告诉我我在做什么错。
和我的代码:

// Set up the scene, camera, and renderer as global variables.
var scene, camera, renderer;
init();
animate();
// Sets up the scene.
function init() {
// Create the scene and set the scene size.
scene = new THREE.Scene();
var WIDTH = window.innerWidth,
HEIGHT = window.innerHeight;
// Create a renderer and add it to the DOM.
renderer = new THREE.WebGLRenderer({antialias:true});
renderer.setSize(WIDTH, HEIGHT);
document.body.appendChild(renderer.domElement);
// Create a camera, zoom it out from the model a bit, and add it to the scene.
camera = new THREE.PerspectiveCamera(35, WIDTH / HEIGHT, 0.1, 100);
camera.position.set(0,0.15,3);
camera.lookAt(new THREE.Vector3(0,0,0));
scene.add(camera);
// Create an event listener that resizes the renderer with the browser window.
window.addEventListener('resize', function() {
var WIDTH = window.innerWidth,
HEIGHT = window.innerHeight;
renderer.setSize(WIDTH, HEIGHT);
camera.aspect = WIDTH / HEIGHT;
camera.updateProjectionMatrix();
});
// Set the background color of the scene.
renderer.setClearColor(0xd3d3d3, 1);
// Create a light, set its position, and add it to the scene.
var light = new THREE.PointLight(0xffffff);
light.position.set(0,200,100);
scene.add(light);
// Load in the mesh and add it to the scene.
var loader = new THREE.PLYLoader();
loader.load( './models/foot.ply', function ( geometry ) {
geometry.computeVertexNormals();
geometry.center();
var material = new THREE.MeshStandardMaterial ({ shininess: 1000,vertexColors: THREE.FaceColors } );
var mesh = new THREE.Mesh( geometry, material );
mesh.position.x = 0;
mesh.position.y = 0;
mesh.position.z = 0;
mesh.castShadow = false;
mesh.receiveShadow = false;
scene.add( mesh );
} );
// Add OrbitControls so that we can pan around with the mouse.
controls = new THREE.OrbitControls(camera, renderer.domElement);
controls.userPanSpeed = 0.05;
}
// Renders the scene and updates the render as needed.
function animate() {
// Read more about requestAnimationFrame at http://www.paulirish.com/2011/requestanimationframe-for-smart-animating/
requestAnimationFrame(animate);
// Render the scene.
renderer.render(scene, camera);
controls.update();
}

编辑:因为我没有单独的纹理,所以这不是重复的问题。
代替使用MeshStandardMaterial
使用MeshBasicMaterial
