提供Building类继承Prism类的方法，实现建筑物的绘制。可以通过 API 设置楼面坐标或者BuildingInfo对象、高度、侧面/顶面颜色、侧面/顶面纹理以及动画配置。

let latlng = new LatLng(23.008468, 113.72953)
let search: BuildingSearch = BuildingSearch.newInstance();
search.requestBuilding({ latlng })
    .then((res: BuildingResult) => {
    if (!!res.buildingList) {
        res.buildingList.forEach(item => {
            if (item.geom) {
               this.appendBuilding(item)
            }

        })
    }
})
    
appendBuilding(item: BuildingInfo) {
    let build = new Building({
        buildingInfo: item,
        sideFaceColor: Color.Blue,
        topFaceColor: Color.Green,
        floorColor: Color.Yellow,
        floorHeight: (item.height ?? 0) - 10,
        isRoundedCorner: true,
        roundedCornerRadius: 2,
        buildingFloorAnimateType: FloorAnimateType.AnimateSlow
    })
    this.mapController.addOverlay(build);

}
