Hello Cyrille, Cool ! I didn't know this method with [alpha] and [polygon_smooth]. I get good results here with this method, better than render 4 times a primitive and translate it by 1/2 pixel with alpha. Maybe it depends on what you need to render ? Thanks to this info, my computer will be cooler :) ++ Jack _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
