Trying to view source code for a Houdini file
I want to better understand a remarkable paper: https://cseweb.ucsd.edu/~alchern/projects/MinimalCurrent/
The authors provide the source code as a proprietary binary code that can only be opened in Houdini. A .hipnc file. The binary data can be viewed in other applications, but not the source code.
Opening the file with the free licensed version of Houdini shows some graphical output.
However searching around in the documentation and playing with the UI I cannot find a text editor to actually see the source code of what the researchers were doing.
Given the original paper description, I know that the source code is contained in the Houdini file. The authors explicitly say so. But I cannot find documentation describing how to see that source code.
Solution
Houdini is described as an "IDE for computer graphics", and not a typical code/script editor. In the context of this question, the .hipnc file contains a workflow comprising network nodes, which looks something like below in Network View:
Assuming you are interested in the mincurr_FFT_solver node, you can use the built-in Python Shell to get the source code of any given node:
import hou
node = hou.node('/obj/Minimal_Current/mincurr_FFT_solver')
print(node.asCode())
Results when written to file:
# Initialize parent node variable.
if locals().get("hou_parent") is None:
hou_parent = hou.node("/obj/Minimal_Current")
# Code for /obj/Minimal_Current/mincurr_FFT_solver
hou_node = hou_parent.createNode("subnet", "mincurr_FFT_solver", run_init_scripts=False, load_contents=True, exact_type_name=True)
