This can be done with a shader and a framebuffer. The gemwin is not the way to do it because it knows nothing of the geometry being rendered elsewhere in a patch.

Hi, Something I would add to G.E.M. is the "Depth Of Field" effect. Someone asked this last year on pd-list without succes/response : http://lists.puredata.info/pipermail/pd-list/2008-10/065649.html

Adding something like a 'focus' parameter to [gemwin] would be very nice. Maybe it could be done using GLSL or [GEMglAccum] (*) but, until now, all my searches and tests have failed...

Any ideas on how to do that ? I can code a bit a opengl/c, but I have poor skills... So any help, link or idea is welcome !

Best regards, Pierre
