[PD] RE : Re: need help with gem and glsl feedback

[Py Fave]

in fact my problem is not solved .
it seems like the feedback effect  happens everywhere but on the
surface drawn by the shader .

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 .

i would like the dots to have the feedback ,
or dots + geometry alltogether.

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 .

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
