inputing arrays into pdal pipelines?

[spolloni]

I'm thinking it would be useful to allow passing arrays back into PDAL pipelines, for example:

pipeline_json = """
                [
                    {
                        "type": "filters.delaunay"
                    },
                    {
                        "type": "writers.gltf",
                        "filename": "/path/to/mesh.gltf",
                    }
                ]
                """

pipeline = pdal.Pipeline(pipeline_json)
pipeline.validate() 
pipeline.execute(input=some_array)

where some_array is expected to conform to

>>> some_array.dtype
[('X', '<f8'), ('Y', '<f8'), ('Z', '<f8'), ('Intensity', '<u2'), ('ReturnNumber', 'u1'), ('NumberOfReturns', 'u1'), ('ScanDirectionFlag', 'u1'), ('EdgeOfFlightLine', 'u1'), ('Classification', 'u1'), ('ScanAngleRank', '<f4'), ('UserData', 'u1'), ('PointSourceId', '<u2'), ('GpsTime', '<f8'), ('OriginId', '<u4')]

Is this of interest at all? what about ease of implementation?

This is already supported. Pass the arrays into the Pipeline constructor.
