I am developing a videofeedback demo that grabs the image of the stage and
feeds it back into a texturemap on a mesh. This is nothing new of course.

but the main performance problem is that in order to work, the 3d sprite
must be dts=false. that makes it much slower. So i need to find a way to get
the image from the stage with 3d sprite using dts = true.
I'll give both of these tricks a try.
Any other suggestions greatly appreciated.
here is the current state of my 3d video feedback
www.biomorphica.com/shockwave/3dVideoFeedback/FeedBackUI.htm
this is merely v1.1 and is very alpha. Half the UI doesn't work yet.
Like the mesh Deformers are not hooked up, and you'd better avoid the
sampling Rect for now. The Save was actually working in flash, but now
it has shorted out. oi. It is a newborn ans still kinda wobbly.
The way to have fun with it is to spin the UVW tiling or better yet, go
in Figure Texture, and slide the the texture transforms - rotation is
good. Use the blend to fade in the blendConstant on layer 2. The twiddle
the other texture transforms. The Feedback Imaging is not so great
either. The inks (when copypixeling between the stage and the new
bitmap) actually work but they mostly suck. and while the back ground
ink is also hooked up, it doesn't appear to have much of an effect.
