No this is not the OFFICIAL python binding, it's only my side project. It run outside of houdini and only communicate with houdini engine.

I add some object-oriented wrapping of Houdini Engine's API, for example setting parameter, as well as multi-session management I am working on it right now.

Thanks maajor, I'm looking forward to seeing where you are going with this!
Would you know where to find documentation for the “official” bindings? I assume the bindings themselves come with Houdini Engine, but there seems to be no mention of it anywhere but the “Whats new in H18.5” page, and no documentation either.

Hi,
I think the official one is https://www.sidefx.com/docs/houdini/hapi/ [www.sidefx.com]
Looks like it's just like do
hapi = cdll.LoadLibrary("libHAPIL")
in python, so I suppose scripting with it has not much difference with C.
Best Regards,

New Houdini Engine Python API documentation where? Oct. 27, 2020, 3:50 a.m.

Just found this while googling around:

https://pypi.org/project/pyhapi/ [pypi.org]

Is this it? It looks like it's in a very early stage of development?

Anyone knows anything?

I just totally missed the part that I can use hom from regular python shell and make command-line tools with hou module. That of course means that there is no point in such low level API.

Actually I found that somebody did the bindings already: https://pyhapi.readthedocs.io/en/latest/ [pyhapi.readthedocs.io] though I'm not sure how practical it can be. May be in some environment where you can't use python2.7

Hi, glad someone found my python-binding https://github.com/maajor/pyhapi, [github.com] basically it just
  • Wrap houdini engine's C API
  • Provide an object-oriented interface

About use case, I write it just because I made some HDA and doesn't want to launch houdini/maya/unity to use it, so I can process geometry with the HDA in command-line. For example, I made HDA to do rough skinning and simulation, I call with command-line to batch such processing, just like PDG but within command-line.
