Add an object to the SceneGraph

[zitoun]

Hi everyone !

What I call a scenegraph is the hierarchy of all the objects in the scene, including the cameras.
I already have a nice flightpath for my camera, I'd like now to add a small plane in the viewfield of the camera, and a simple way to do so would be to add the plane object to my current camera, with (for the moment) a fixed position + orientation.

However I cannot seem to do so simply in the Sketchup application (or maybe I just missed it).

Any help ?
If this subject has already been treated, would you please be kind enough to post the link on the topics talking about this point, I haven't found it so far !

Thx !!

I used Pixero and Fredo's work to be able to create a sequence where my camera flies all around a room. Now I'd like the plane to be in the camera's field, first as a fixed item, and later moving (while staying in the viewfield).

Most efficient way to do so is to attach the plane to the camera, as you can do in most animation tools. But I understood this would not be easily feasable.

Another way is to get for each frame (from a script maybe) the camera position and orientation, add offline my plane wanted relative position and orientation, and then update my plane's coordinates for each frame.
Maybe using ProperAnimation plugin...
But as I've just discovered SU, I still don't really know how to get these position + orientation infos...
Plus I don't know if it is possible to set offline Proper Animation coordinates for an object !
