LightMap

A LightMap specifies a cube texture light map.

Usage

import {Viewer, Mesh, buildSphereGeometry,
     ReadableGeometry, MetallicMaterial, LightMap} from "xeokit-sdk.es.js";

// Create a Viewer and arrange the camera

const viewer = new Viewer({
     canvasId: "myCanvas"
});

viewer.scene.camera.eye = [0, 0, 5];
viewer.scene.camera.look = [0, 0, 0];
viewer.scene.camera.up = [0, 1, 0];

new LightMap(viewer.scene, {
    src: [
        "textures/light/Uffizi_Gallery/Uffizi_Gallery_Irradiance_PX.png",
        "textures/light/Uffizi_Gallery/Uffizi_Gallery_Irradiance_NX.png",
        "textures/light/Uffizi_Gallery/Uffizi_Gallery_Irradiance_PY.png",
        "textures/light/Uffizi_Gallery/Uffizi_Gallery_Irradiance_NY.png",
        "textures/light/Uffizi_Gallery/Uffizi_Gallery_Irradiance_PZ.png",
        "textures/light/Uffizi_Gallery/Uffizi_Gallery_Irradiance_NZ.png"
    ]
});

// Create a sphere and ground plane

new Mesh(viewer.scene, {
     geometry: new ReadableGeometry(viewer.scene, buildSphereGeometry({
         radius: 2.0
     }),
     new MetallicMaterial(viewer.scene, {
         baseColor: [1, 1, 1],
         metallic: 1.0,
         roughness: 1.0
     })
});
