yes you can do this way, there is another example that Rob made, very
similar to what you want.
its planet earth with smileys, look on away3d.com posts from 2008.
but if its a little plane only...
you just have to copy background rect, paste your plane on source,
next iteration, paste background back, copy new part where you paste,
paste etc etc
or use MovieMaterial. if you set the rectclip before the update, it
will be easy on code and as fast as bmd only.

I found this example from Rob Bateman ...
view = new View3D({session:new BitmapRenderSession(1), clip:new
RectangleClipping(-400, -300, 400, 300)});
var mybitmapData:BitmapData = view.getBitmapData();
where a bitmap "session" is used instead of a "scene" ... as opposed
to what I do currently:
view = new View3D({scene:scene,
camera:camera,renderer:Renderer.BASIC});
apparently this allows you to grab a bitmap image of the rendered view
then apply effects to it (here's the post):

However, I don't understand the difference between a view as a
"session" and a view as a "scene" ... ?
Is this even the right dirrection for what I want to do?

I have a sphere with a bitmapfile material applied to it. I want to
"project"/"draw"/"overlay" a smaller bitmap file onto the sphere
bitmap. i.e. create the earth with bitmap file and sphere
primitive ... now show a small airplane bitmap "flying" along the
surface of the earth with position updated each frame render.
I've looked at the Away3dTextureProjection demo and it's uber cool
but
I take a huge perf hit (I'm working with alot of objects).
Using shaders to do "overlays" and I get a huge perf hit (working
with
alot of different objects).
It seems like I should be able to "grab" the bitmap image on the
sphere, place the smaller airplane on some point on the sphere bitmap
and put them together back on sphere each enter frame ... ???? If
this
is possible how do I get access to the bitmap and plop the airplane
onto it?
Cheers in advance.
