可能重复:
如何使材质显示在球体上
// set the scene size
var WIDTH = 1650,
HEIGHT = 700;
// set some camera attributes
var VIEW_ANGLE = 100,
ASPECT = WIDTH / HEIGHT,
NEAR = 0.1,
FAR = 10000;
// get the DOM element to attach to
// - assume we've got jQuery to hand
var $container = $('#container');
// create a WebGL renderer, camera
// and a scene
var renderer = new THREE.WebGLRenderer();
var camera = new THREE.PerspectiveCamera( VIEW_ANGLE,
ASPECT,
NEAR,
FAR );
//camera.lookAt(new THREE.Vector3( 0, 0, 0 ));
var scene = new THREE.Scene();
// the camera starts at 0,0,0 so pull it back
camera.position.x = 200;
camera.position.y = 200;
camera.position.z = 300;
// start the renderer
renderer.setSize(WIDTH, HEIGHT);
// attach the render-supplied DOM element
$container.append(renderer.domElement);
// create the sphere's material
var sphereMaterial = new THREE.MeshLambertMaterial(
{
color: 0xCC0000
});
我认为这是问题所在... Frome here...
var sphereGeo, sphereTex, sphereMat, sphereMesh;
var radius = 60, segments = 20, rings = 20;
sphereGeo = new THREE.SphereGeometry(radius, segments, rings);
sphereTex = THREE.ImageUtils.loadTexture('cube.png', null, function () {
sphereMat = new THREE.MeshBasicMaterial({map: sphereTex});
sphereMesh = new THREE.Mesh(sphereGeo, sphereMat);
scene.add(sphereMesh);
});
到这里……对吧?
// and the camera
scene.add(camera);
// create a point light
var pointLight = new THREE.PointLight( 0xFFFFFF );
// set its position
pointLight.position.x = 50;
pointLight.position.y = 100;
pointLight.position.z = 180;
// add to the scene
scene.add(pointLight);
// add a base plane
var planeGeo = new THREE.PlaneGeometry(500, 500,8, 8);
var planeMat = new THREE.MeshLambertMaterial({color: 0x666699});
var plane = new THREE.Mesh(planeGeo, planeMat);
plane.position.x = 160;
plane.position.y = 0;
plane.position.z = 20;
//rotate it to correct position
plane.rotation.x = -Math.PI/2;
scene.add(plane);
// add 3D img
var img = new THREE.MeshBasicMaterial({
map:THREE.ImageUtils.loadTexture('cube.png')
});
img.map.needsUpdate = true;
// draw!
renderer.render(scene, camera);
我想在我的球体上添加我的 img 纹理......现在它只是一个黑色的平面,球确实出现了,但它没有纹理,所以你看不到它......我如何在球体上获得纹理?
