filters.splitter

The splitter filter breaks a point cloud into square tiles of a size that you choose. The origin of the tiles is chosen arbitrarily unless specified as an option.

The splitter takes a single PointView as its input and creates a PointView for each tile as its output.

Splitting is usually applied to data read from files (which produce one large stream of points) before the points are written to a database (which prefer data segmented into smaller blocks).
