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 !
