Methods
static Cesium.BoxGeometry.createGeometry(boxGeometry) → Geometry|undefined
Computes the geometric representation of a box, including its vertices, indices, and a bounding sphere.
Name | Type | Description |
---|---|---|
boxGeometry |
BoxGeometry | A description of the box. |
Returns:
The computed vertices and indices.
static Cesium.BoxGeometry.fromAxisAlignedBoundingBox(boundingBox) → BoxGeometry
Creates a cube from the dimensions of an AxisAlignedBoundingBox.
Name | Type | Description |
---|---|---|
boundingBox |
AxisAlignedBoundingBox | A description of the AxisAlignedBoundingBox. |
Returns:
Example:
const aabb = Cesium.AxisAlignedBoundingBox.fromPoints(Cesium.Cartesian3.fromDegreesArray([
-72.0, 40.0,
-70.0, 35.0,
-75.0, 30.0,
-70.0, 30.0,
-68.0, 40.0
]));
const box = Cesium.BoxGeometry.fromAxisAlignedBoundingBox(aabb);
