基于three.js开发的GIS框架

基于three.js开发的GIS框架。

在线demo: http://124.223.202.45/VGIS-Examples/vin3gis

Display a map

const mapViewer = new Vin3GIS.MapViewer({
    target: "map-div",
    imageryTileProivder: new Vin3GIS.AMapImageryTileProvider()
});

Display 3dtiles

const initCameraPosition = new THREE.Vector3(121.506, 31.238, 16500 * 0.7);
const initCameraOrientation = new THREE.Vector3(0, -90,0);
const homeViewPort = new Vin3GIS.ViewPort(
    Vin3GIS.Cartographic.fromDegrees(
        initCameraPosition.x,
        initCameraPosition.y,
        initCameraPosition.z
    ),
    Vin3GIS.Orientation.fromDegreeEulerAngles(initCameraOrientation)
);

    target: "map-div",
    imageryTileProivder: new Vin3GIS.AMapImageryTileProvider({
        style: "aerial",
    }),
    homeViewPort: homeViewPort,
    camera: {
        near: 0.001
    }
});

技术路线

大佬，可否整理一下实现思路进行技术分享一下，阅读源码好些不理解，可以分享一下联系方式吗？
