Hi,

first of all: awesome work.

second: I have searched for a couple of hours but I can't find a way to restrict a 3D terrain model to some lat/lng rectangle or box.

I want to create a 3D map, but like one of these plastic maps: with a rectangular base. I don't want to see the horizon, it should look and feel like a small model...

Like this: [http://www.walkgps.com/images/Three%20Mountains%20walk\_3Dmap.JPG](http://www.walkgps.com/images/Three%20Mountains%20walk_3Dmap.JPG)

My guess is it would feel very natural to look at and orient at will...

The best example online I could find is this: [http://potree.org/demo/potree\_2014.12.30/examples/matterhorn.html](http://potree.org/demo/potree_2014.12.30/examples/matterhorn.html)

If possible this should also restrict the amount of computational work I think...

Thanks in advance, this would be so great...

Greetings Lon

Hello,

I don’t think it is currenlty possible to only render a part of the map. However, we do have a 2.5D mode we call Columbus View that is a 2D map with height. Here is an example with terrain:

var viewer = new Cesium.Viewer(‘cesiumContainer’, {  
terrainProvider: new Cesium.CesiumTerrainProvider({  
url : ‘[https://assets.agi.com/stk-terrain/world](https://assets.agi.com/stk-terrain/world)’,  
requestWaterMask : true,  
requestVertexNormals : true  
}),  
baseLayerPicker: false,  
sceneMode: Cesium.SceneMode.COLUMBUS\_VIEW  
});

``

Best,

Hannah
