Trying to view source code for a Houdini file
问题
我想更好地理解一篇卓越的论文：https://cseweb.ucsd.edu/~alchern/projects/MinimalCurrent/
作者提供的源代码是一个专有的二进制代码，只能在Houdini中打开。一个.hipnc文件。二进制数据可以在其他应用程序中查看，但无法查看源代码。
使用Houdini的免费许可版本打开文件会显示一些图形输出。
然而，在文档中搜索并尝试使用用户界面，我找不到文本编辑器来实际查看研究人员所做工作的源代码。
根据原始论文的描述，我知道源代码包含在Houdini文件中。作者明确如此说明。但我找不到描述如何查看该源代码的文档。
英文:
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.

根据@adabsurdum在meta上的评论，.hipnc文件可以在纯文本编辑器（如vi或emacs）中打开。它包含一些二进制数据块，我不确定它是否实际上对您理解作者正在做什么有用，但它不难查看。
它类似于在未压缩的PDF或PostScript文件中看到的内容 - 基本上是以（大部分）纯文本表达的图形原语。
例如，前几行是（从emacs中复制粘贴的）：

以及第26112行和以下内容：

As commented on meta by @adabsurdum, the .hipnc file can be opened in a plain-text editor such as vi or emacs. It does have some binary blobs in it, and I don't know if it will actually be useful as 'source code' to help you understand what the authors are doing, but it's not hard to examine.
It's similar to what you would see in an uncompressed PDF or PostScript file - basically, graphics primitives expressed in (mostly) plain text.
For example, the first few lines are (copy-pasted from emacs):
HouNC^Z1033600baa06089de3b09a7e5953.start^@fplayback -i on -r off -f 1 -e on -h on -t on -a on -k on -s 1tcur 0fps 24tset 0 10frange 1 240unitlength 1unitmass 1prompt '`strcat(oppwf(), " -> ")`'HouNC^Z1033600ba606089de3b043eebadb.variables^@set -g ACTIVETAKE = 'Main'set -g DRIVER = 'mantra_ipr'set -g DRIVERPATH = '/out/mantra_ipr'set -g E = '2.7182818284590452354'set -g EYE = 'stereo'set -g HIP = '/Users/achern/Documents/MinimalCurrent/supplementary'set -g HIPFILE = '/Users/achern/Documents/MinimalCurrent/supplementary/mincurr.hipnc'set -g HIPNAME = 'mincurr'set -g JOB = '/Users/achern'set -g PI = '3.1415926535897932384'set -g POSE = '/Users/achern/Library/Preferences/houdini/16.0/poselib'set -g _HIP_SAVEPLATFORM = 'macosx10.14-x86_64-clang10.0-targetosx10.12'set -g _HIP_SAVETIME = 'Wed Apr 28 15:14:19 2021'set -g _HIP_SAVEVERSION = '18.0.532'set -g _HIP_SHELFTOOLCOUNT = '14'set -g status = '0'

Houdini 被描述为“计算机图形的集成开发环境”，而不是传统的代码/脚本编辑器。在这个问题的上下文中，.hipnc 文件包含了一个由网络节点组成的工作流，看起来类似于 Network View 中的以下内容：
[][链接]
假设您对mincurr_FFT_solver节点感兴趣，您可以使用内置的Python Shell获取任何给定节点的源代码：
import hounode = hou.node('/obj/Minimal_Current/mincurr_FFT_solver')print(node.asCode())
写入文件时的结果：
# 初始化父节点变量。if locals().get("hou_parent") is None:hou_parent = hou.node("/obj/Minimal_Current")# 用于 /obj/Minimal_Current/mincurr_FFT_solver 的代码hou_node = hou_parent.createNode("subnet", "mincurr_FFT_solver", run_init_scripts=False, load_contents=True, exact_type_name=True)hou_node.move(hou.Vector2(1.25615, -5.79144))hou_node.bypass(False)hou_node.setDisplayFlag(False)hou_node.hide(False)hou_node.setHighlightFlag(False)hou_node.setHardLocked(False)hou_node.setSoftLocked(False)hou_node.setSelectableTemplateFlag(False)hou_node.setSelected(True)hou_node.setRenderFlag(False)hou_node.setTemplateFlag(False)hou_node.setUnloadFlag(False)hou_parm_template_group = hou.ParmTemplateGroup()# 参数模板的代码hou_parm_template = hou.StringParmTemplate("label1", "Input #1 Label", 1, default_value=(["Sub-Network Input #1"]), naming_scheme=hou.parmNamingScheme.Base1, string_type=hou.stringParmType.Regular, menu_items=([]), menu_labels=([]), icon_names=([]), item_generator_script="", item_generator_script_language=hou.scriptLanguage.Python, menu_type=hou.menuType.Normal)hou_parm_template_group.append(hou_parm_template)# 参数模板的代码# 以下省略其他参数模板的代码...# 将参数模板组添加到节点hou_node.setParmTemplateGroup(hou_parm_template_group)# 以下省略每个参数的设置代码...
您可以根据需要使用这些代码片段创建和设置节点参数。
英文:
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:
<!-- language-all: lang-py -->
import hounode = 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_solverhou_node = hou_parent.createNode("subnet", "mincurr_FFT_solver", run_init_scripts=False, load_contents=True, exact_type_name=True)hou_node.move(hou.Vector2(1.25615, -5.79144))hou_node.bypass(False)hou_node.setDisplayFlag(False)hou_node.hide(False)hou_node.setHighlightFlag(False)hou_node.setHardLocked(False)hou_node.setSoftLocked(False)hou_node.setSelectableTemplateFlag(False)hou_node.setSelected(True)hou_node.setRenderFlag(False)hou_node.setTemplateFlag(False)hou_node.setUnloadFlag(False)hou_parm_template_group
