我正在尝试使用three.js在线编辑器做一个法线贴图实验。编辑器很棒，如下所示：

没有法线贴图：

导出时的问题，对我来说最重要的是材质，但看起来导出器没有导出材质设置，如着色器或制服：

            }]
    }
}

我知道编辑器正在进行中，所以这可能还没有实现，但是你知道在构建场景时是否有办法从编辑器中查看生成的代码？我可以看到代码对我来说应该足够了。

谢谢 ：）

对不起，伙计们，我想出了如何让法线贴图工作，我仍然不知道如何从编辑器中查看代码，但无论如何我都会关闭这个问题......感谢那些花时间阅读它的人。

             //wall
              var textures = {
                lion: THREE.ImageUtils.loadTexture('../media/lion.png'),
                lionbumpnormal: THREE.ImageUtils.loadTexture('../media/lion-bumpnormal.png')
              };

                // common material parameters

                var ambient = 0, diffuse = 0x331100, specular = 0xffffff, shininess = 10, scale = 23;
                var material = new THREE.MeshPhongMaterial( {
                    map: textures.lion,
                    normalMap: textures.lionbumpnormal,
                    color: 16580351,
                    ambient: 16777215,
                    emissive: 0,
                    specular: 13027014,
                    shininess: 60,
                    opacity: 1,
                    transparent: false,
                    wireframe: false
                } );

              var planeGeometry = new THREE.PlaneGeometry(10, 10);

              var wall = new THREE.Mesh(
                  planeGeometry,
                  material
                );

不确定这是否是您的意思，但我试图加载我在编辑器中设置的简单场景。能够使用 THREE.ObjectLoader 做到这一点

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <title></title>
    <script src="../three.js/build/three.js"></script>
    <script>
      (function() {
        var Game = function() {
        }

        Game.prototype.init = function() {
          var loader = new THREE.ObjectLoader();
          loader.load('data.json', (function(data) {
            this.scene = data;
            this.load();
          }).bind(this));
        }

        Game.prototype.draw = function() {
          this.renderer.render(this.scene, this.camera);
        }

        Game.prototype.load = function() {
          var container = document.createElement('div');
          document.body.appendChild(container);

          this.camera = new THREE.PerspectiveCamera(30, window.innerWidth / window.innerHeight, 1, 10000);
          this.camera.position.z = 500;
          this.camera.position.x = 500;
          this.camera.position.y = 100;
          this.camera.lookAt(new THREE.Vector3(0,0,0));
          this.scene.add(this.camera);

          this.renderer = new THREE.WebGLRenderer();
          this.renderer.setSize( window.innerWidth, window.innerHeight);
          container.appendChild(this.renderer.domElement);
          this.update();
        };

        Game.prototype.update = function() {
          requestAnimationFrame(this.update.bind(this));
          this.draw();
        }

        window.onload = function() {
          var g = new Game();
          g.init();
        }

      }).call(this);
