Seeing what's inside SOP nodes?

[paolousero]

So learning about Houdini.

 

I want to know how I can see the innards of these nodes like Carve, wireframe, and whatever - see how it manipulates the data and spits it out at the output. People have been saying to look at the HDK - so I'm just now looking at the Node Organization stuff on the SDK. Everything seems to be just APIs and header files though. :/

 

Any tips?

You can't look inside atomic SOP operators, they are compiled HDK code and closed-source. There are small number of exceptions, like Mountain SOP, which is VEX type style SOP. In later case you could open Operator Type Properties window and look at the Code tab. HDK examples live in $HFS/toolkit/samples folder. Maybe some of them are actual nodes sources.

Note that all "enterable" SOP nodes have blue text, like a subnet/HDA. so its easy to see which ones you can dive into.
