    Syntax

    subbpcds = partition(bpcds,n,index)

    Description

    subbpcds = partition(bpcds,n,index) partitions the blocked point cloud datastore bpcds into the specified number of parts n, and returns the partition corresponding to the specified index index.

    Open Live Script

    Create a blocked point cloud.

    pcfile = fullfile(toolboxdir("lidar"),"lidardata", ...
                       "las","aerialLidarData.laz");
bpc = blockedPointCloud(pcfile,[300 300]);

    Create a blockedPointCloudDatastore from the blocked point cloud.

    bpcds = blockedPointCloudDatastore(bpc);

    Partition the blocked point cloud datastore into two partitions, and create a new blockedPointCloudDatastore object from the data in the first partition.

    bpcdsp1 = partition(bpcds,2,1);

    Read data and metadata from the first partition. Display the metadata.

    while hasdata(bpcdsp1)
      [data,info] = read(bpcdsp1);
      disp(info)
end
