Thank you,

here in english again:
I try to change my Baum3D-program (look http://www.kbuechner.gmxhome.de) to a C++-Plugin.
It is heavy for me to understand it, but it makes fun.
Later I can compile it also for Mac-User.

If you like, you can test it (be carefully with number of recursions)

Please decompress followed files to your C4D-Plugins-directory:

http://www.kbuechner.gmxhome.de/Baum_Plugin.zip

My questions (the first an second answered by Jack soon) :
- how I can generate a second object to texture it separatly(leafs)?
- how can I create a drag-and-drop-field,the user can take any leaf-polygon-object (my also be an apple), and how can I use it in my program?

new question:
- how can I fit the start-view to the size of the tree, to see the whole tree?

thanks,
Klaus

CallCommand(12151L) will "Frame Active Objects". That means that you'll have to set the objects as selected.

This is untested so verify its veracity.

This will depend on if the field is in the Attributes Manager or a Dialog (they have different interfaces). For the Attributes Manager, you create a LINK description in the res file (or dynamically using GetDDescription() in the NodeData for the plugin). For a Dialog, you'll need to use a custom gui element:

> // LinkBox \> BaseContainer tbc; \> tbc.SetBool(LINKBOX_HIDE_ICON, FALSE); \> // this variable is stored in the dialog class for later \> copyLinkBox = (LinkBoxGui\* )AddCustomGui(IP_COPY_SOURCE,CUSTOMGUI_LINKBOX,String(),BFH_SCALEFIT|BFV_SCALEFIT,0L,0L,tbc); \> if (!copyLinkBox) return FALSE;

You'll need to check Message() for drag-n-dop here:

> // GeDialog.Message \> //\*---------------------------------------------------------------------------\* \> LONG IPPDialog::Message(const BaseContainer& msg, BaseContainer& result) \> //\*---------------------------------------------------------------------------\* \> { \> //GePrint(BaseContainerToString(msg)); \> LONG mid = msg.GetId(); \> if (mid == BFM_DRAGRECEIVE) return Msg_DragReceive(msg, result); \> else if (mid == BFM_GETCURSORINFO) return Msg_GetCursorInfo(msg, result); \> return GeDialog::Message(msg, result); \> } \> // IPPDialog.Msg_DragReceive - BFM_DRAGRECEIVE \> //\*---------------------------------------------------------------------------\* \> LONG IPPDialog::Msg_DragReceive(const BaseContainer& msg, BaseContainer& result) \> //\*---------------------------------------------------------------------------\* \> { \> // Copy-Paste LinkBox \> if (!CheckDropArea(IP_COPY_SOURCE, msg, TRUE, TRUE)) return GeDialog::Message(msg, result); \> if (msg.GetLong(BFM_DRAG_LOST)) return GeDialog::Message(msg, result); \> \> LONG cursor = MOUSE_POINT_HAND; \> LONG type = 0L; \> void\* object = NULL; \> BaseObject\* op = NULL; \> \> GetDragObject(msg, &type;, &object;); \> \> if ((type == DRAGTYPE_ATOMARRAY) && (((AtomArray\* )object)->GetCount() == 1L) && ((AtomArray\* )object)->GetIndex(0)) \> { \> op = (BaseObject\* )((AtomArray\* )object)->GetIndex(0L); \> if (op->IsInstanceOf(Obase) && (op->GetTag(ID_IPPFIGURETAG) || op->GetTag(ID_IPPOBJECTTAG))) cursor = MOUSE_INSERTCOPY; \> else \> { \> cursor = MOUSE_FORBIDDEN; \> op = NULL; \> } \> } \> \> if (msg.GetLong(BFM_DRAG_FINISHED)) \> { \> copyLinkBox->SetLink(op); \> copySource = op; \> copyDoc = op->GetDocument(); \> } \> \> return SetDragDestination(cursor); \> }

thank you very much, I will try it.

But the other problem:
How can I create 2 objects.
I have to return in GetVirtualObjects one Object.
And the other ?

You can group the virtual object under a virtual Null object for instance. Check the Atom object example in the SDK.

I go crazy. What is wrong?
I try to insert the tree and leafs under the Plugin, but it dont't work. Otherwise, if I convert it with 'c' to a polygon-object, it is right.

// this is the source-code:
BaseObject *CBaumPlugin::GetVirtualObjects(PluginObject *op, HierarchyHelp *hh)
{
BaseObject *ret = BaseObject::Alloc(Onull);

BaseObject *botree = tree.op;//pointer to the tree
BaseObject *boleafs = leaf.op;//pointer to the leafs
botree->SetName("tree");
boleafs->SetName("leafs");
botree->InsertUnderLast(ret);
boleafs->InsertUnderLast(ret);
// also tryed with: ret->InsertUnderLast(botree);

return ret;

}

what is wrong ?

I don't know maybe something wrong with your tree.op/leaf.op pointers? I tried a simple example with a cube and a sphere inserted under a null and this works fine.

thank you,

exactly so i had made it.

But I see in the C4D-object-manager only my Plugin without sub-items.

But when I convert (with key 'c') ist, I see it.

???

All the objects you create are virtual! They are NOT visible in the OM. If you want to create the polygon objects in the OM, you better use a GeDialog gui (See gui sdk examples) where the user can hit a button to create the objects in the OM, but then you loose interactivity of a c4d object.

As Katachi notes, virtual objects are 'virtual' - they only exist for the purpose of the deformations/generations/rendering processes and nothing more. Beyond that, they *really* don't exist in the document and there are restrictions on what can be done with/to them (see the C++ SDK Documentation).

I have an idea: I don't need two objects.
To texture separately, it is enough to create two polygon-selections!
But I don't now again, how I can make it

Hello,

Plugin is almost ready.
Thanks for help.

Screenshot here:
http://www.kbuechner.gmxhome.de/BaumPlugiScreen.jpg

It is for C4D 9.1 but works likely in higher versions (now only Windows)

Download here:
http://www.kbuechner.gmxhome.de/Baum_Plugin.zip

To make leafs, you must insert a polygon-object under the Plugin (make it unvisible for renderer).
These texture-coordinaten were adopted.

The you must give the plugin one tree- and one leaf-texture.
Important: name the Selektion per texture "tree" and "leafs", these are hidden polygon-selektions.

in future:
- leaf-angle
- gravitation
- wind (you can simulate it now by animating "Biegung"(bend)
- tree withot middle-twig
- fitting the start-view to whole tree
- dimension-frame
- Mac-Version
- ????
