Hi, Maxime, I'm trying to be able to browse through every point, the tangents of those points, and the segments they belong to. It seems like a LineObject wouldn't help me get the tangents or the spline point locations so I think I would need the actual SplineObject.

I want to output a SplineObject, taking in the input splines points, tangents, and segments to be able modify it and return something different.

I hope that clears it up,
Dan

Thanks! That worked for me!

Hi Ferdinand,

Thanks for the reply!

When you said to add volume.framework, did you mean like this? I'm working from the SDK examples for this test.

// Supported platforms - can be [Win64;OSX]
Platform=Win64;OSX

// Type of project - can be [Lib;DLL;App]
Type=DLL

// API dependencies
APIS=\
asset.framework;\
cinema.framework;\
cinema_hybrid.framework;\
crypt.framework;\
core.framework;\
command.framework;\
image.framework;\
math.framework;\
mesh_misc.framework;\
volume.framework;\
python.framework;

// C4D component
C4D=true

stylecheck.level=0 // must be set after c4d=true
stylecheck.enum-registration=false
stylecheck.enum-class=false

// Custom ID
ModuleId=net.maxonexample.cinema4dsdk

It doesn't seem to me working for me here, with maxon/volume.h not being found. I've tried a few others things but none of them seem to be working. Do I need to add the framework somewhere else as well?

Thanks again,

Dan

Hello! I was trying to get the Volume Object example working that's in the SDK here:
https://developers.maxon.net/docs/Cinema4DCPPSDK/html/page_manual_volumeobject.html

I'm having trouble having it successfully compile though.

The two headers I'm including:
#include "lib_volumeobject.h"
#include "lib_volumebuilder.h"

    BaseObject* object = static_cast<BaseObject*>(node->GetDown());
    
    // create VolumeObject
    // This example checks if the given object is a volume builder.
    // If so, it accesses the cache to get the VolumeObject.
   
    if (object == nullptr)
        return true;
    // check if VolumeBuilder
    if (object->IsInstanceOf(Ovolumebuilder) == false)
        return true;
   
    VolumeBuilder* const volumeBuilder = static_cast<VolumeBuilder*>(object);
   
    // get cache
    BaseObject* const cache = volumeBuilder->GetCache(nullptr);
    if (cache == nullptr)
        return true;
   
    // check for volume object
    if (cache->IsInstanceOf(Ovolume))
    {
      const VolumeObject* const volumeObject = static_cast<VolumeObject*>(cache);
   
      const maxon::VolumeInterface* volInterface =   volumeObject->GetVolume();
    
     const maxon::String  gridname2 = volInterface->GetGridName();
        //Error:: Member access into incomplete type 'const maxon::VolumeInterface'
     
        
        const maxon::Volume       volume = volumeObject->GetVolume();
     // Error::   No type named 'Volume' in namespace 'maxon'
        
        
      const maxon::String gridName = volume.GetGridName();
      DiagnosticOutput("Grid Name: @", gridName);
    }

I'm having problems with these two bits:

const maxon::VolumeInterface* volInterface =   volumeObject->GetVolume();

const maxon::String  gridname2 = volInterface->GetGridName();
//Error:: Member access into incomplete type 'const maxon::VolumeInterface'
         
            
const maxon::Volume       volume = volumeObject->GetVolume();
// Error::   No type named 'Volume' in namespace 'maxon'

Is there some sort of header that I need to include or is the example out of date?

Thanks for any help!

Dan

I checked it out and the issue is resolved!

Dan

Thanks Manuel,

I don't seem to have access to that level of the beta, but when I do I'll be sure to test it!

Hello, I'm experiencing a difference between 2023 and 2023. If I add a Constraint tag to a Cube in both versions they behave differently when made Editable.

In 2023 when there is a Constraint tag and the Cube is made Editable the Constraint Tag remains on the now Polygon Object.

In 2023.1 when there is a Constraint tag and the Cube is made Editable the Constraint Tag disappears on the now Polygon Object.

I'm seeing the same behavior on one of my plugins, where is now disappears, and I don't know if this is a bug or something I need to solve for. Any idea what the cause of this would be?

Dan

Hi Manuel,

I didn't think about CopyTo being called on undo. That might be all I need then, thanks. I did a couple tweaks and as of now everything is perfect.

Dan

Hello! I had a more general question about the proper way to do something within Cinema.

I want to have a 'Bake' button on my plugin that will do some of the heavy lifting as a single step, so that these calculations don't need to be done on a per update basis. I could create the needed data structures once and use those instead of constantly rebuilding them.

My question is what is the best way to implement this. My initial thought was to use a BaseArray of a custom Class to store the needed data. Something along the lines of one entry per child object to keep track of relationships and choices. Is this a valid way to go about it?

I was running into some problems with Read and Write, converting the Class to be read and written could be done though. One thing I was stumped on is that if I Free my BaseArray when the object is deleted then how would I bring it back if Undo was used?

Thanks for any help,
Dan

@m_adam Hi!

Thanks for looking into it!

Hi @ferdinand,

No worry on any delay. I did some addition checking with the description resource and I even completely removed the resource folder but I'm having the same thing happen, so that doesn't seem to be playing a part as far as I can tell.
