Thank you, Riccardo. That was exactly what I was doing wrong.

Hello, I'm trying to find all of the visible points from the point of view of a given BaseDraw. It seems like CalculateVisiblePoints() should be exactly what I need, but I'm not getting results that make any sense to me.

It seems like the function would do exactly what I'm looking for and a search only turned up a thread about it not being available in Python from years ago. I've seen other threads about getting visible object points, but I wanted to see if CalculateVisiblePoints() would work before moving onto one of those.

My tests have just involved a polygon cube and rotating around it, but the visible points aren't consistent with the view.

My current code:

    BaseObject* child =op->GetDown();
    if(child== nullptr ||child->GetType() != Opolygon)
    {
        return;
    }
   
    PolygonObject* polyobj = static_cast<PolygonObject*>(child);
    BaseDraw* bd = doc->GetActiveBaseDraw();
    if(bd==nullptr)
    {
        return;
    }
    Vector* vectors = polyobj->GetPointW();
    UChar* results;
    if (CalculateVisiblePoints(bd, polyobj, vectors, results, TRUE) == FALSE)
    {
        return;
    }
   
    Int32 pointcount =polyobj->GetPointCount();
    for (Int32 x=0; x<pointcount; x++)
    {
        
        if (results[x] ==1)
        {
            ApplicationOutput(String::IntToString(x) + " Visible");
        }
        else if (results[x] ==0)
        {
            ApplicationOutput(String::IntToString(x) + " Not Visible");
        }
        else
        {
            ApplicationOutput("-Empty-");
        }
        
    }

Thanks for any help,

Thank you both for the replies! Between both of them I have exactly what I need, thanks.

Hello, I'm looking for a way to get the filepaths from the Preferences -> Plugins -> Search Paths menu. I have a circumstance where one plugin needs to know where another plugin is installed so I want to be able to check those remote paths, but I can't figure out how to access the parameter.

GetWorldContainer() doesn't seem to contain this parameter but it does others, so I'm not sure where to go from here.

Dan

Thank you both for the answers!

Sorry about not finding that, Sebastian, it wasn't popping up when I searched the SDK.

Hello!
I have a pretty simple question about how to create a twirl down group in the Attribute Manager such as this

I managed to track down that it uses DESC_PARENT_COLLAPSE, but I'm having trouble setting it up in GetDDescription(). The SDK doesn't really help with it and the forums didn't turn up any results so I'm a bit lost. Thanks for any help.

Hello!

I'm working on a plugin were I want to take an input child object spline and use its points as a basis for an output. I'm able to get when the object is dirty reliably and only update when I have to. But when I have an object like an Oinstance or an Oconnector, I'm not getting a dirty message from them if the object inputting into them has been updated.

Aside from manually checking the object type and checking INSTANCEOBJECT_LINK and CONNECTOBJECT_LINK respectively I can't figure out a way to get if they have actually updated and therefore I have to update.

Is there way to get the dependence list for a given object so I can manually check it? Since the linked connect/instance isn't being marked as dirty I don't know another approach to use. Or is there a better way to know when an input into one of those objects has updated?

Dan

I understand, that makes sense to me.

Thank you for the help.

Hi Manuel, no worry about the wait! Thanks for the help.

When you say that there is a special case for the Text spline "Make Editable", do you mean core unique Cinema functionality? That's not something I can replicate, right?

Hi Manuel,

I think I understand! Definitely a few limitations but it seems doable.

I had a follow up question about how the Text object behaves in Cinema, since making it editable can return multiple splines. When Separate Letters is checked the object returns multiple splines underneath a null, but not when the checkbox is off. Would that be via GVO() or GetContour()? Does the function that gets called depend on the Seperate Letters checkbox?

Text Test.c4d

Additionally when a Text object is made editable when Separate Letters is checked it no longer works underneath an Extrude object, which makes sense because of the null. But it works when its before its been made editable. Is this just because the null doesn't exist internally?
