forge 中如何手动控制小地图的放大与缩小

Answer 1

通过点击桌面来控制小地图的放大与缩小

let minMapTool = viewer.getExtension("Autodesk.AEC.Minimap3DExtension").tool
document.onclick = function(e){
    let targetZoomLevel = minMapTool.parent.targetZoomLevel;
    //每次缩放等级+0.1
    let zoomLevelNew = targetZoomLevel +=0.1;
    var zoomLevelMax = minMapTool.parent.getMaxZoomLevel();
    var zoomLevelMin = minMapTool.parent.getMinZoomLevel();
    zoomLevelNew = THREE.Math.clamp(zoomLevelNew, zoomLevelMin, zoomLevelMax);
    minMapTool.parent.setZoomLevel(zoomLevelNew, false);
   
}
