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. This
promise will reject if the terrain provider's `availability` property is undefined.
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.sampleTerrainMostDetailed(terrainProvider, 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.sampleTerrainMostDetailed(terrainProvider, positions, true);
} catch (error) {
// A tile request error occurred.
}
Stereographic(position, tangentPlane)
engine/Source/Core/Stereographic.js 19
Represents a point in stereographic coordinates, which can be obtained by projecting a cartesian coordinate from one pole onto a tangent plane at the other pole.
The stereographic projection faithfully represents the relative directions of all great circles passing through its center point.
To faithfully represents angles everywhere, this is a conformal projection, which means points are projected onto an arbrary sphere.
