Create Polyhedron from points (in grid)

CesiumJS
1

I have grid of points, which I have created from the following function:

function(rectangle, gridWidth, gridHeight) {

gridWidth = parseInt(gridWidth) || 41;

gridHeight = parseInt(gridHeight) || 41;

var terrainSamplePositions = ;

for (var y = 0; y < gridHeight; ++y) {

for (var x = 0; x < gridWidth; ++x) {

var longitude = Cesium.Math.lerp(rectangle.west, rectangle.east, x / (gridWidth - 1));

var latitude = Cesium.Math.lerp(rectangle.south, rectangle.north, y / (gridHeight - 1));

var position = new Cesium.Cartographic(longitude, latitude);

terrainSamplePositions.push(position);

}

}

return terrainSamplePositions;

}

``

After it I have added height information to those points

now the array have the **Cartographic **position with the updated height info

After it, I want to create a Polyhedron from this points

Can someone help me on it?

I’m using Cesium 1.50.

Here the image with the points(I have added extra height for visual separation purpose):

I think you’ll have to create a custom geometry. This article might be a good reference as well https://cesiumjs.org/tutorials/Geometry-and-Appearances/

You can also check out the various geometry types in the Cesium source code to see how they use the Geometry class.

This is looking pretty good, you should post a screenshot once you get it working!
