Hello,

in fact my problem is not solved .
it seems like the feedback effect happens everywhere but on the
surface drawn by the shader .
According to the patch, the feedback is applied on a [square 4]
(where there is also the [torus 2]).
Then, [gemframebuffer] 'snap' the whole 'inside' [square 4]. And
your torus is inside this snapshot (as texels and not vertices).
i use a torus , in perspective wich has a shader applied .
i tried the following workaround(archive is joined ) , but still no luck .
the file to open has a OPEN in name .
It seems there is no circle4.geom, [receive13] and [nshader0]
objects/abstractions in your .zip.
i would like the dots to have the feedback ,
or dots + geometry alltogether.
I can't see dot in your patch (or gem window), maybe they come from
geometry shader (which is missing) ?
i tried pix_snap2tex ( using gems.feedback from pdmtl abstractions) too
but no luck because we can't choose the mixing function .
and i would like only white to make trails .
and i don't know how to keep the supporting geometry from appearing .
the torus should be full black with a white trail only .
A simple possibility is to use 2 torus, a black 'on' a white. And
use the white for the trail ?
An other way :
white torus as texture
|__> in the feedback __> output feedback as texture
|__> convert white in black texel __> output black torus as
texture
Then mix (multiply) black torus with white feedback to get a black
torus with white trails.

btw i'm on windows not my choice.
i have to share the screen with other programs wich are windows only
any help welcome once more .
Thanks
Pierre-Yves
