After modifying the source code, when executing underground mode, set the background color of the map, synchronize the translucent operation of the map image, and refresh the image layer to display the effect in time.// Set map basecolor to transparent

viewer.scene.globe.baseColor = new Cesium.Color(1, 1, 1, 0);/ /Cycle to set transparency of image

var _mapAlpha = 0.5;

if (viewer.imageryLayers) {

for (var i = 0; i < viewer.imageryLayers.length; i++) {

viewer.imageryLayers.get(i).alpha = _mapAlpha;

}

}

//Refresh all image slices

viewer.scene.globe._ surface.invalidateAllTiles();

Transparent surface effect, showing half above ground and underground

In the above image, the transparency of underground mode is realized, but there is still a shadow floating underground. This is Cesium's own atmospheric effect. If you need to turn it off, this effect will not exist. viewer.scene.skyAtmosphere.show = false;

There is no problem with black shadows in the above image. The whole scene has turned black. Therefore, when using the map, the dark base image will appear very dark and the specific effect cannot be seen clearly.
