Yep, that's why Cyrille says that you can use [pix_snap] or [pix_snap2tex].
like in exemple 07.texture/07.feedback
Or you can also use [gemframebuffer].
like in exemple 10.glsl/06.framebuffer and shader, but removing the
shader.With that, you can capture a certain part of your last frame and
add it to your new. But the result could be not very nice.why?
I was sure that a blur appear after a certain period. But i am wrong.
So there is no problem to use this objects to simulate single buffer
in double buffer mode !

yes, but my problem is : I need to emulate single buffer on
double buffer, i need to use double buffer because i work with iterations using
repeat or until objects, and in single buffer with metro this iterators are
so so so slow, almost "2" fps.wow, it's strange that it is slower in single buffer. do you have a test patch that demonstrate this?
i want don´t clear the image buffer when is drawed the new
buffer, like an accumulation...but using double buffer!!....is possible???...in
single buffer is easy, but with iterators....no way.i don't understand why iterators can't work in single buffer.

thanks for your patience.

hello,
is possible in gem to change between single buffer and double
buffer without destroy gemwindow??no
or dont`t clear buffer(background image) in double buffer???
not really, but you can sna2tex and draw the last image on every
frame.you can also easily emulate 2 buffer while in single buffer,
using metro to bang gemhead and clean windows / clear Z buffer.Cyrille
thanks a lot!!!
