three加载hdri

As an AI language model, I cannot perform 3D rendering tasks. However, I can provide you with steps on how to load HDRI in Three.js.

1. First, you need to create an instance of the HDRI loader:

var loader = new THREE.HDRILoader();

2. Then, load the HDRI file using the loader:

loader.load(
    'path/to/hdri/file.hdr',
    function (texture) {
        // The texture has been loaded successfully
    },
    function (xhr) {
        // Called while loading is progressing
        console.log((xhr.loaded / xhr.total * 100) + '% loaded');
    },
    function (error) {
        // Called if an error occurs while loading
        console.error('An error happened');
    }
);

3. Once the texture is loaded, you can create a cube map and assign it to your scene's environment:

var cubeMap = new THREE.CubeTexture( /* ... */ );
cubeMap.mapping = THREE.CubeReflectionMapping;
cubeMap.format = THREE.RGBFormat;
cubeMap.generateMipmaps = true;
cubeMap.needsUpdate = true;

var environment = new THREE.PMREnvironmentMap( cubeMap, 0.5 );
scene.environment = environment;

These are the basic steps to load and use an HDRI in Three.js. You can customize the parameters to suit your needs.
