I am not sure, what are you trying to achieve? Object plugins are for creating new object types (generators, deformers, effectors etc.).
cheers,

Okay, I got that.
The achievement is to gain access to the camera's region of interest (that what the camera can see) leading to derive some kind of view-dependency.
As mentioned in another thread refinement will occur on an object by splitting edges and connecting new polygons in dependence of the viewing of the camera - the result should be, that the refinement is in the camera's visible area greater than at the back of the object - what the cam cannot see (cause it is hidden by the polygons facing towards the camera). I am not sure about using the EditorCamera for this via BaseDraw...

Ok, then the best way I think would be to get the editor camera from the active BaseDraw or alternatively use a Link field in your object's description where you can drag a custom camera.

Is it possible to map the BaseDraw-View to an animateable custom camera automatically? Otherwise the link field would be the alternative...

Just check for a scene camera with GetSceneCamera() and if NULL use GetEditorCamera(). This way you can use an own camera or just use the editor camera.
Also it's probably a good idea to obtain the BaseDraw with GetRenderBaseDraw().

Hey all
I use this now:
BaseDraw *draw = doc->GetRenderBaseDraw();
BaseObject *cam = draw->GetEditorCamera();
It seems this can only be mapped to a BaseObject.
I wonder how to change the objects position.
BaseContainer *cn = cam->GetDataInstance();
cn->SetVector(???,Vector(0,1000,-5000));
Which ID should be set here if this works to change its position ?
If there's no chance creating a targeted camere or sth like this, i should use the link field, cause the editorcam cannot be animated. I just wanted to doff some activities from the user.
Cheers

Hmm, I don't know why i overlooked that ?!
Okay right now, I create a scene camera manually before executing my plugin :
> \> BaseDocument \*doc = op->GetDocument(); \> BaseDraw \*draw = doc->GetRenderBaseDraw(); \> BaseObject \*cam = draw->GetSceneCamera(doc); \> if(!cam) cam = draw->GetEditorCamera(); \> \> LONG x= cam->GetPos().x; \> LONG y= cam->GetPos().y; \> LONG z= cam->GetPos().z; \> GePrint("X: "+LongToString(x)+", Y: "+LongToString(y)+", Z: "+LongToString(z)); \>
So far this works - thanks to you.
I wonder if it is possible to create a targeted scene camera before the other steps in my plugin...
Cheers

Watch your value types. The values are Real. For quicker access, you can go like this (for instance) :
> Vector cpos = cam->GetPos();
> GePrint("X: "+RealToString(cpos.x)+", Y: "+RealToString(cpos.y)+", Z: "+RealToString(cpos.z));
You can use LongToString() and the Real will be converted to Long printing integer values nonetheless.
As for the targeted scene camera, I think that you will need to construct this yourself. Just requires two additions to the camera object: a null object and a Target Expression tag added to the camera object. You will need to set the "Target Object" link field on the tag to link the camera to the null object.
You do this by getting the tag's BaseContainer and setting the appropriate ID:
> BaseObject* nobj = BaseObject::Alloc(Onull);
> if (!nobj) return FALSE; // error condition
> doc->InsertObject(nobj, NULL, NULL, FALSE);

Hey Robert,
thanks for this advice. You are absolutely right. I forgot, that Vector uses Real datatype.
Hmm... afaik doc->InsertObject() is not allowed inside a GetVirtualObjects()-function ?! I am still operating on my generator plugin...
I am afraid I have very less knowledge about execution priority of functions within plugins
In atom.cpp Recurse() is called within GetVirtualObjects() without producing multiple objects on redraw, what I can't understand. The boolean variable "dirty" is set to false in GetVirtualObjects() and given to Recurse() but it never changes... I have no idea how to bring more than one object into the document when using a generator plugin. Perhaps I should port everything to a command plugin... *sigh*
Edit:
Well using a command plugin everything works so far. *great happyness*
But just for knowledge, how can more objects than the generated one be "inserted" in GetVirtualObjects()
Thanks to you all 
Cheers
Sascha

Hey again, sorry for pushing this one to the top again, but I recently recognized an issue with my camera set into the scene i do not understand.
As a few know, I am developing a plugin calculating a planets surface via CLOD depending on the view point.
In this post I asked for adding a camera to a scene via code.
This is done. The camera is allocated and insterted into the document.
Using these two lines
BaseDraw *draw = doc->GetRenderBaseDraw();
draw->SetSceneCamera(cam);
I am able to look through my camera. So far so good.
When my calculation ends, it seems they've been made from looking through the default editor's view and not the camera's view. Did I miss to set something for my camera or the base draw ?
Cheers
