1. 导入RGBELoader模块：

   import { RGBELoader } from "three/examples/jsm/loaders/RGBELoader.js";

使用 

  addRGBEMappingk(environment, background,url) {

      rgbeLoader = new RGBELoader();
      rgbeLoader.loadAsync(url).then((texture) => {
        //贴图模式 经纬线映射贴图
        texture.mapping = THREE.EquirectangularReflectionMapping;
        //背景贴图
        if (background) {
          this.scene.background = texture;
        }
        //环境贴图
        if (environment) {
          this.scene.environment = texture;
        }
      });
}

调用

let url ="./images/FFThree/hdr/hj.hdr"

addRGBEMappingk(true, true, url );

使用CubeTexture实现球体和街道环境贴图

addRGBEMappingk(environment, background, urlsix){
{
      //     // 加载环境贴图
      // 加载周围环境6个方向贴图
      // CubeTexture表示立方体纹理对象，父类是纹理对象Texture
      const textureCube = new THREE.CubeTextureLoader()
        .setPath(urlsix)
        .load(["px.png", "nx.png", "py.png", "ny.png", "pz.png", "nz.png"]);
      if (background) {
        //背景贴图
        this.scene.background = textureCube;
      }
      if (environment) {
        //环境贴图
        this.scene.environment = textureCube;
      }
    }
}

调用

let urlsix: "./images/FFThree/hdr/back/"

addRGBEMappingk(true, true, urlsix);

添加金属球看效果

 addSphere() {
    //金属球
    const sphereGeometry = new THREE.SphereGeometry(5, 30, 30);
    const material = new THREE.MeshStandardMaterial({
      metalness: 0.9, // 金属材质 1 黑
      roughness: 0.1, //光滑
    });
    const sphere = new THREE.Mesh(sphereGeometry, material);
    sphere.position.set(20, 5, 0);
    this.scene.add(sphere);
    return sphere;
  },
