Three.js 中的纹理

Question

我正在尝试将纹理应用于 three.js 中的 birds example。

  // instantiate a loader
  var loader = new THREE.TextureLoader();

  // load a resource
  loader.load('imgs/birdtexture.jpg', function (texture) {
     var material = new THREE.MeshBasicMaterial( {
     map: texture,
     side: THREE.DoubleSide
  });

  var bird = new THREE.Mesh( new Bird(), material);
);

出于某种原因，这不起作用，而且我没有收到任何错误。看来我遗漏了什么。我做错了什么？

编辑： 我按照描述 here 使用 UV 使其工作。这是代码：

  var texture = new THREE.TextureLoader().load("imgs/birdtexture.jpg");
  texture.wrapS = THREE.RepeatWrapping;
  texture.wrapT = THREE.RepeatWrapping;
  texture.repeat.set( 0.05, 0.05);

  var geometry = new Bird();

  function assignUVs(geometry) {

  geometry.faceVertexUvs[0] = [];

  geometry.faces.forEach(function(face) {

    var components = ['x', 'y', 'z'].sort(function(a, b) {
        return Math.abs(face.normal[a]) > Math.abs(face.normal[b]);
    });

    var v1 = geometry.vertices[face.a];
    var v2 = geometry.vertices[face.b];
    var v3 = geometry.vertices[face.c];

    geometry.faceVertexUvs[0].push([
        new THREE.Vector2(v1[components[0]], v1[components[1]]),
        new THREE.Vector2(v2[components[0]], v2[components[1]]),
        new THREE.Vector2(v3[components[0]], v3[components[1]])
    ]);

    });

    geometry.uvsNeedUpdate = true;
    }

    assignUVs(geometry);

    var bird = new THREE.Mesh( geometry, new THREE.MeshBasicMaterial(     {map:texture, side: THREE.DoubleSide }));

Answer 1

试试这个（未测试）：

  // instantiate a loader
  var loader = new THREE.TextureLoader();
  // Create material
  var material = new THREE.MeshBasicMaterial({side: THREE.DoubleSide});

  // load a resource
  loader.load('imgs/birdtexture.jpg',   function (texture) {
     marterial.map = texture;
  });

  var bird = new THREE.Mesh( new Bird(), material);
);
