Cesium 与 Babylon.js 可视化 添加路灯

我决定不从Babylonjs 基础来讲了 直接整合cesium与babylonjs可视化来讲

我整合一个类库 后续不断更新中

• npm i @haibalai/cesium-babylonjs

 

初始化cesium-babylonjs 类库， viewer 是 Cesium 的 viewer对象

• import { BabylonMapManager } from "@haibalai/cesium-babylonjs";
• BabylonMapManager.init(viewer);

 

添加正方体

• import { BabylonMapManager } from "@haibalai/cesium-babylonjs";
• let scene = BabylonMapManager.getScene(map);
• const lampLight = new BABYLON.SpotLight("lampLight", BABYLON.Vector3.Zero(), new BABYLON.Vector3(0, -1, 0), Math.PI, 10, scene);
• lampLight.diffuse = BABYLON.Color3.Yellow();
• //shape to extrude
• const lampShape = [];
• for(let i = 0; i < 20; i++) {
• lampShape.push(new BABYLON.Vector3(Math.cos(i * Math.PI / 10), Math.sin(i * Math.PI / 10), 0));
• }
• lampShape.push(lampShape[0]); //close shape
• //extrusion path
• const lampPath = [];
• lampPath.push(new BABYLON.Vector3(0, 0, 0));
• lampPath.push(new BABYLON.Vector3(0, 10, 0));
• for(let i = 0; i < 20; i++) {
• lampPath.push(new BABYLON.Vector3(1 + Math.cos(Math.PI - i * Math.PI / 40), 10 + Math.sin(Math.PI - i * Math.PI / 40), 0));
• }
• lampPath.push(new BABYLON.Vector3(3, 11, 0));
• const yellowMat = new BABYLON.StandardMaterial("yellowMat");
• yellowMat.emissiveColor = BABYLON.Color3.Yellow();
• //extrude lamp
• const lamp = BABYLON.MeshBuilder.ExtrudeShape("lamp", {cap: BABYLON.Mesh.CAP_END, shape: lampShape, path: lampPath, scale: 0.5});
• //add bulb
• const bulb = BABYLON.MeshBuilder.CreateSphere("bulb", {diameterX: 1.5, diameterZ: 0.8});
