Is there a utility that can be used to create a Polygon/Polygon Hierarchy based on a Shaped that is described with a series of Move To, Line To, Close To segments?
Does the Polygon Hierarchy expect that the holes are completely contained in the outer positions array?
Any input would appreciated.
Welcome to the community! What exactly do you mean by a polygon hierarchy?
The Cesium api defines a Polygon Hierarchy as a set of positions and holes. The holes is a polygon hierarchy itself. See PolygonHierarchy - Cesium Documentation
The sandcastle has a demo using it. But in testing if a position of a hole is not contained within the outer positions the shape does not fill correctly.
