This Quartz Composer patch renders 100000 particles , using an image as a basis for extrusion . It uses OpenCL to control particle positions over the time ( thereby it needs Quartz Composer 4.0 to be able to run) .

Supersampling, Feedback & Full Screen rendering

& with a little further experimenting and thought, the following occurred to me.

Put the incapable of doing full screen Billboard into another RII and feed that the Feedback result and feed the resulting RII output to another suitably blended and configured Billboard, just in case you didn't already know.

set to 2d , with texture mapping flagged & with enabled feedback rendering, the final RII provides the best full screen output [won't dispute that it does lop the top and bottom off the screen, but the performance is far brisker , no doubt in part , due to the constraining of the rendering space made by the 2D setting.

I kind of wondered ....

what was that image ?

Then I adjusted the dampening and got a little more perspective [X-Ray vision on :-)]
