How to draw cross section of Terrain Data

[dharavat...@gmail.com]

I want to draw cross section of terrain object. I am not able to get any support from anywhere... Any help from anyone is appreciated..

Thanks

Hm, I'm not sure what you mean by a cross section of terrain, since the terrain is a single layer and not a dense solid that you can cut into. 

This sandcastle example shows how a clipping plane cuts through terrain and lets you see what that would look like. Is that close to what you want?

Hello!

Clipping planes seem like what you would want. Let me know if I missed what you want, but is it like what you would get if you pasted the following code into Sandcastle?

var viewer = new Cesium.Viewer('cesiumContainer', {
    skyAtmosphere: false,
    terrainProvider: Cesium.createWorldTerrain()
});

var globe = viewer.scene.globe;

globe.clippingPlanes = new Cesium.ClippingPlaneCollection({
    planes : [
        new Cesium.ClippingPlane(new Cesium.Cartesian3( 1.0, 0.0, 0.0), 0.0),
        new Cesium.ClippingPlane(new Cesium.Cartesian3( 0.4, 0.3, 0.4), 0.0)
    ],
    edgeWidth: 1.0,
    edgeColor: Cesium.Color.WHITE,
    enabled : true
});

Here's a bit about clipping planes!
