vdb_ax - utility for processing OpenVDB data using AX

DESCRIPTION

usage: vdb_ax [command] [--help|-h] [-v] [<args>]

CLI utility for processing OpenVDB data using AX.
-h, --help, -help

print help and exit

-v, --verbose

verbose (print timing and diagnostics)

[execute] read/process/write VDB file/streams (default command):

-i [file.vdb]

append an input vdb file to be read

-s [code], -f [file]

input code to execute as a string or from a file

-o [file.vdb]

write the result to a given vdb file

--opt [NONE|O0|O1|O2|Os|Oz|O3]

compilation optimization level (Default: 03)

--threads [n]

number of threads to use, 0 uses all available (Default: 0)

--werror

warnings as errors

--max-errors [n]

maximum error messages, 0 allows all error messages (Default: 0)

--copy-file-metadata

copy the file level metadata of the first input to the output

Volumes:

--create-missing [ON|OFF]

whether to implicitly create volumes (Default: ON)

--tree-level [l1|l1:l2]

a node level or node range to process (Default: 0:4)

--node-iter [ON|OFF|ALL]

the active state type of nodes to process (Default: ON)

--tile-stream [ON|OFF|AUTO]

set the active tile streaming behaviour (Default: AUTO)

--volume-grain [g1|g1:g2]

threading grain size for processing nodes (Default: 1:32)

--bindings ["ax_name:volume_name,..."]

attribute bindings for volumes

Points:

whether to implicitly point attributes (Default: ON)

--group [name]

a point group to process

--points-grain [n]

the threading grain size for processing nodes (Default: 1)

--bindings ["ax_name:point_attr_name,..."]

attribute bindings for points

[analyze] parse code and run analysis:

--ast-print

print the generated abstract syntax tree

--re-print

re-interpret print of the code post ast traversal

--reg-print

print the attribute registry (name, types, access, dependencies)

--try-compile <points | volumes>

attempt compilation for points, volumes or both if no option is provided

[functions] query available function information:

--list <filter-name>

list functions, their documentation and their signatures
