关于javascript:3d-获得最大距离和限制最大最小距离

限度最大间隔,默认为2，设为3能够拉的更远，设为1能够限度的更近
viewer.navigation.setZoomOutLimitFactor(3)
限度最小间隔,默认为200，只针对2d
viewer.navigation.setZoomInLimitFactor(300)

取得最大间隔

function getMaxDis() {    var maxFactor = viewer.navigation.getZoomOutLimitFactor(); if(viewer.toolController.getActiveTool().getName() == "orbit"){    var computeOverviewDistance = viewer.navigation.computeOverviewDistance(viewer.toolController.getActiveTool().getFitBounds()); var maxDis = maxFactor * computeOverviewDistance; return maxDis    }    return ;}
