Boole Object causes version 2024 to freeze

[ThomasB]

Hi,

for demonstration purposes, I have an extremely stripped down version (1200 LOC) of my plugin (6000 LOC) here.
Unfortunately it was not possible to insert the whole Pyp file here because the post can only be a maximum of 32767 characters long. That's why I only have sent the classes and functions that are not so important are without code.

• Condition: the window bars must be activated. Error with Boole happens in the method

def bar_cutter(op, obj, bars, fixed=False)

---

Description:

Of course, it is not technically perfect and in this version it is more of a prototype. I was able to narrow down the error to the Bars_Cutter() function. That's why I only included the bar_cutter method.

• In this function I read specific points from the created frame and create a spline, which I throw into an Extrude and then convert to a polygon object. this extrude is used to cut the window bars.
• I then create a Boole object and throw the previously created bars together with the extrude into the Boole object.

Normally I also create a polygon object from the Boole object with SendModelingCommand() but to prove that the error comes from the Boole, I insert the Boole object directly under the window frames.

---

Problem:

The problem now is this. If you reduce the arch height of this arched window, the polygons will now intersect. The following usually happens (R23-2023). The bars then simply disappear. And the glass is no longer displayed correctly either. That's actually OK. The user immediately knows that something is intersected. (Watch Video)

And in version 23-2023.2 this works, as can be seen in the video.
But in version 2024 when the polygons intersect, Cinema 4d freezes.

I have a short video to watch here.

Also the version of the plugin in a zip file for R23-2023 and 2024 for easy reference.
Boole-Problem.zip

It actually only happens when the intersection of the intersected polygons creates a slightly deformed extruder.

---

Question:

Why does this freeze in 2024... Version and in R23-2023 not?

---

Temporary Solution:

I was now able to get around the problem by calculating the points of the extrude, how many there should be if Arch Subd has a certain value. When the polygon interesects, the extrude suddenly has more points. And I'll check that. If there are more, I simply don't create the Boole anymore. Then it works......

For demonstration purposes, I only sent the content of the plugin, not the res, header and str files. These are then included in the plugin itself. I hope that's ok.

Hey @ThomasB,

Thank you for reaching out to us. As a minor side note - when you want to embed an mp4 video, you must give it its own line/paragraph, otherwise the embedding won't trigger. I have fixed that for you in your posting.

I gave your plugin a spin and tried to recreate your bug conditions, but at least in 2024.2 Win was unable to trigger the bug (see video at the end of my posting). When my answer does not help, you should consider describing your bug more precisely. You should have a look at Support Procedures: Reporting Bugs.

But despite the fact that your plugin runs fine on my machine, there is one thing that sticks out in your code, namely that you misuse SendModelingCommand. When you run SMC from a threaded context such as GetVirtualObjects, you are bound by the threading restrictions and therefore cannot alter a loaded document, e.g., the document your plugin instance lives in.

You however pass multiple times op.GetDocument() as doc to SMC. I.e., you try to run SMC in the document your node is contained in. This is a threading violation which easily can lead to a freeze in 2024 with its C++ API overhaul. What you also do, and what is even worse, is that you pass a document as doc where your SMC operand is actually not a member of. You do this for example here in bar_cutter:

extrude = c4d.BaseObject(c4d.Oextrude)
extrude[c4d.EXTRUDEOBJECT_FLIPNORMALS] = normal
extrude[c4d.EXTRUDEOBJECT_EXTRUSIONOFFSET] = direction
extrude.SetName("Glass")
glass_spline.InsertUnder(extrude)

extrude: c4d.PolygonObject = c4d.utils.SendModelingCommand(
    command=c4d.MCOMMAND_CURRENTSTATETOOBJECT,
    list=[extrude.GetClone()],
    doc=op.GetDocument())[0]

extrude is not a member of the document of op, it is in fact not a member of any document. In smc_extrude_s26.py I once dissected the subject of how to run SMC in different scenarios. In the bar_cutter case things are quite easy since extrude is an orphaned node anyway. You can just insert it into a dummy document you create. When you then want to include extrude in the output of your GetVirtualObjects, you must not forget to remove it from your dummy document again (extrude.Remove()) as nodes can only be part of one document.

When you are still running into problems, please provide a more precise freeze report (exact c4d and OS version, as well as a step-by-step in reproduction list as shown in Support Procedures: Reporting Bugs).

Cheers,

Running your plugin on my Windows machine in 2024.2.

My console, despite the print out, I have loaded the 2024.0 version and am running 2024.2.

Hello Ferdinand,
Thank you very much first of all.
yes, you're right, I worked extremely sloppily with the SMC method, of course I'll take the threading into account and also work with a Temp Document.

Regarding the problem itself, I can only say that reinstalling CINEMA 4D solved our problem.

Cheers
