abcstats

Given one or more Alembic archives, this script will traverse each archive's objects and properties, and accumulate the following statistics:

• Number of files and total file size in bytes
• Number of IObjects
• Total occurrences of each schema
• Total array length of all array properties (keyed on schema name + property path)

Example Output

The script will produce some output like this:

Total AbcGeom_Camera_v1: 8
Total AbcGeom_PolyMesh_v1: 10
Total AbcGeom_PolyMesh_v1/.faceCounts: 2232
Total AbcGeom_PolyMesh_v1/.faceIndices: 8712
Total AbcGeom_PolyMesh_v1/N: 912
Total AbcGeom_PolyMesh_v1/P: 2144
Total AbcGeom_PolyMesh_v1/uv/.indices: 8064
Total AbcGeom_PolyMesh_v1/uv/.vals: 2288
Total AbcGeom_Xform_v3: 18
Total File Count: 9
Total File Size (Bytes): 4892874
Total IObject Count (excl. top): 36
Total IObject Count (incl. top): 45

Usage

The abcstats script can be given one or more paths to alembic archives, e.g:

abcstats box.abc sphere.abc

If no file paths are given, the script will attempt to read a list of files via stdin. This is particularly handy for piping the results of find to the script, e.g:

find . -name "*.abc" | abcstats

The command can optionally take the following flags:

• -h / --help: print help message and exit
• -d / --distinct: filter out duplicate file paths (off by default)

Requirements

To use this script, the Alembic python bindings must be available in your python environment.
