## Did you read the Contributor Guide? - [x] Yes ## Is this PR related to a ticket? - [x] Yes — closes [#3042](https://github.com/apache/sedona/issues/3042); follow-up to the Box3D EPIC ([#2973](https://github.com/apache/sedona/issues/2973)) and the Flink slices #3037 (foundation) and #3040 (accessors / ST_3DExtent). ## What changes were proposed in this PR? Final Flink Box3D slice. Brings the Flink predicate surface to parity with Spark's Box3D predicates (consolidated into `ST_Intersects` / `ST_Contains` plus the standalone `ST_3DDWithin`). - **`ST_Intersects` / `ST_Contains`**: Box3D `eval` overloads wrapping `Predicates.box3dIntersects` / `box3dContains`. Mirrors the Box2D overloads already on these classes. - **`ST_3DDWithin`**: new scalar function with two overloads — `(Geometry, Geometry, Double)` → `dWithin3D` (missing Z folds to 0), and `(Box3D, Box3D, Double)` → `dWithin3D`. NULL-guarded like the Box overloads. Registered in `Catalog`. ## How was this patch tested? - `PredicateTest.testIntersectsOnBox3D` / `testContainsOnBox3D` — XY-overlapping-but-Z-disjoint rows confirm the Z axis is enforced (not just an XY-footprint check). - `PredicateTest.test3DDWithin` — Geometry POINT Z within / just-outside the threshold, plus Box3D-on-Box3D faces-apart-in-Z within / just-outside. - Full `PredicateTest`: 21 pass. ## Did this PR include necessary documentation updates? - [x] No — Box3D documentation is tracked separately under the Box3D EPIC. ## Completion This completes Flink Box3D parity with the shipped Spark surface: type + serializer, constructors, accessors, `ST_AsText`, `ST_3DExtent`, and predicates. -- This is an automated message from the Apache Git Service.
