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 ?pix_snap2tex and antialiasing did not gives blur here. at least with the attached patch. but i thik it used to. i would not be surprised if that would depend on the driver/ hardware...
could you try this patch?
Yep, i get blur here. MacOSX.4.11, Pd version 0.41.4-extended-rc2, GEM ver: 0.91.3 'tigital' I will test tomorrow on Ubuntu 9.04. ++
