Description

I would like to propose a new feature for turf java, namely polygonal intersection, which is as explained in the turf doc as a method that:

Takes two polygon or multi-polygon geometries and finds their polygonal intersection. If they don't intersect, returns null.

It might help on various occasions while dealing with area-specific features on Android apps, for example, intersecting camera bounds with certain polygons can make a huge deal in making area-aware functionalities.

While looking for such a solution I've encountered geok library:
https://github.com/piruin/geok - written in Kotlin, that apparently achieves this goal, so maybe it may be some kind of inspiration.

Research direction

Start by reviewing the Turf intersection behavior described in the issue and the linked geok library for polygon and multi-polygon handling. Done means providing polygonal intersection for two supported geometries, returning null when they do not intersect, with behavior checked against representative Android use cases.
