rejectOnTileFail |
boolean |
false |
optional |
If true, for a failed terrain tile request the promise will be rejected. If false, returned heights will be undefined. |
Returns: |
A promise that resolves to the provided list of positions when terrain the query has completed. |
Example: |
// Query the terrain height of two Cartographic positions |
const terrainProvider = await Cesium.createWorldTerrainAsync(); |
const positions = [ |
Cesium.Cartographic.fromDegrees(86.925145, 27.988257), |
Cesium.Cartographic.fromDegrees(87.0, 28.0) |
]; |
const updatedPositions = await Cesium.sampleTerrain(terrainProvider, 11, positions); |
// positions[0].height and positions[1].height have been updated. |
// updatedPositions is just a reference to positions. |
// To handle tile errors, pass true for the rejectOnTileFail parameter. |
try { |
const updatedPositions = await Cesium.sampleTerrain(terrainProvider, 11, positions, true); |
} catch (error) { |
// A tile request error occurred. |
} |
