Python: Continuous cooking / realtime mode

[Jason]

Hi all,

I'm playing about with some python which I'd like to cook within the event loop of Houdini. I'd like to cause certain SOPs to cook all the time, as I'm trying to do some kind of realtime stuff.

Has anyone done this before? Should I try to dirty a SOP so that it'll cook? Should I force-cook a SOP? Does anyone have any ideas or experience doing that from within the event loop?

Thanks.

Jason

Wooo. Interesting.

I see...

hou.ui.addEventLoopCallback()

hou.ui.triggerUpdate()

hou.Node.cook(...)

So....

Doing this

def rtCook():
    hou.node("/obj/geo1/add1").cook(True)

hou.ui.addEventLoopCallback(rtCook)

Is making my Add SOP cook like a busy little bee.

I require sleep but hopefully this inspires various evilness.

Neat!

Two questions...

What do you use to navigate the HOM to search for functions like the three you mention? You say "I see...", but what did you do to see those?

Do you see anything that will limit the recooking to only happen when something changes (like an object is moved, or a viewport is tumbled.

Thanks!
