[PD] recursive video feedback in GEM or PDP?
The other night I watched a very nice lecture from Paul Prudence (dataisnature.com). He uses to make audio-responsive video feedback, where a single shape (a square) is recursively displayed, causing very complex structures to arise. The relevant parts of the lecture are here: http://www.vimeo.com/2930699 http://www.vimeo.com/3003040 although I would encourage people to go through the whole thing (11 parts on Vimeo) if they have time + interest. I'd at a loss to think of how something similar, i.e. the recursive feedback, could be done in GEM or PDP. Any suggestions? best!

Re: [PD] recursive video feedback in GEM or PDP?
this was the old way to do (but still working fine). i think it can be faster to render in a framebuffer, and use this framebuffer as a texture to draw in a 2nd framebuffer. and drawing back to the 1st. etc. there are also some example in the glsl section. jack also send a simple exemple somwhere recently. ++ c Derek Holzer a écrit : Thanks much!

Re: [PD] recursive video feedback in GEM or PDP?
Second question: would I gain anything by bridging between GEM and PDP for something like this? Or would the [gem2pdp] and [pdp2gem] use more resources than I would gain from using PDP in this situation? D.

Thank you so much for that filter. I was really struggling with figuring out how to utilize [gemframebuffer] and this gives me a place to start. Could this be incorporated into the [gemframebuffer] help patch? That help patch is seriously lacking. Also, if someone could fill me/everyone in about what the [pix_texture] second inlet is for, that would be fantastic.
