The Houdini Object Model (HOM) is an application programming interface (API) that lets you get information from and control Houdini using the Python scripting language.
The HOM cookbook provides short examples using the hou module. The files used
by the cookbook are located in
$HFS/houdini/help/hom/cookbook, and can
also be found in cookbook_files.tar.gz.
For other information about HOM, see the overview documentation.
