参考情報

This is not a bug per se, but rather a limitation of the algorithm used in the 3D environment, and as such, there is no immediate fix. The 3D algorithm may produce unexpected results when polygons are either self-intersecting or contain holes that do not follow the counter-clockwise winding rule. Refer to the suggested workaround to ensure consistent behavior between 2D and 3D displays. Aligning the behavior across 2D and 3D for such datasets is currently on our backlog but has not yet been scheduled for a future release.

対処法

Polygon geometries are encoded as a series of rings. Filled rings must have vertices ordered clockwise, while holes must have vertices ordered counter-clockwise. Additionally, the sequence of the rings is important: the first ring is interpreted as a filled polygon, followed by any number of holes. After that, another filled ring may follow, along with its associated holes, and so on.

If the holes intended for the first filled ring are placed after a subsequent filled ring, they will not be applied as expected. To ensure correct rendering in Scene Viewer, the ring order must be strictly followed.

Adding the following JSON to addFeatures will produce the expected result:
