GeoRegion3D

new Cesium.GeoRegion3D(point3DsArray)

The three-dimensional object class. A 3D surface geometry object is composed of one or more parts. Each part is called a sub-object of the 3D surface geometry object. Each sub-object is represented by an ordered set of three-dimensional coordinate points Point3Ds, and its starting point and ending point coincide.
Name Type Description
point3DsArray Array Point3Ds array.

Members

partCount : Number

Get the number of sub-objects of the 3D surface geometry object.
Default Value: 0.0

Methods

addPart(point3Ds) → Number

Add a sub-object to the 3D area object.
Name Type Description
point3Ds Object The point string of the 3D plane object.
Returns:
If it succeeds, it returns the index number of the added child object; if it fails, it returns -1.

getPart(index) → Object

Get the 3D point object array of the sub-object with the specified index number in the 3D area object.
Name Type Description
index Number The index number of the sub-object in the 3D area object (greater than or equal to zero).
Returns:
If it succeeds, it returns the Point3Ds object; if it fails, it returns a null value.
