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 !blur can appear, under cettain condition, with antialiasing /
quality 1 to the texture or small displacement. but you can avoid it if you wish.
Yep, there is blur with antialiasing and with [pix_snap] and
[pix_texture] (with quality 0 or 1) or with [pix_snap2tex]. But it
seems to be OK with [gemframebuffer] and [pix_texture] (with quality
0 or 1).
Have you an other method to avoid blur with [pix_snap] and
[pix_snap2tex] with antialiasing ?

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!!!
