Three.js (or simply, "three") is a JavaScript library used for creating 3D graphics in a web browser. HDR (High Dynamic Range) is a technique used in computer graphics to simulate a wide range of brightness and color values that are more representative of what we see in the real world. By using HDR, scenes can appear more lifelike and realistic.
In Three.js, there are a few ways to incorporate HDR into your 3D scenes. One way is to use an HDR texture as an environment map, which can be done using the `THREE.TextureLoader` and `THREE.CubeTextureLoader` classes. Another way is to use a library like `THREE.HDRCubeTextureLoader`, which is specifically designed for loading HDR environment maps.
Once you have your HDR environment map loaded, you can use it to light your scene using `THREE.PMREMCubeUVPacker` and `THREE.PMREMGenerator`, which are classes that help generate and pack the necessary textures for HDR lighting.
Overall, using HDR in Three.js can greatly enhance the realism and visual quality of your 3D scenes.
