Houdini Object Model
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. HOM replaces the functionality of Houdini’s previous scripting solutions, the expression language and HScript.
In Python, the package is the top of a hierarchy of modules, functions, and classes that define the HOM. The
hou module is automatically imported when you are writing expressions in the parameter editor and in the
hython command-line shell.
