[PD] recursive video feedback in GEM or PDP?

2009-03-31 Thread Derek Holzer
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:

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

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. Derek Holzer wrote: which objects could be used to make this framebuffer? d. cyrille

Thanks. I know that it is inherent in the system, but is there a way to control the fuzziness of each iteration, so that the image loses its alpha value but retains the sharpness of it's outlines? D. cyrille henry wrote: Derek Holzer a écrit : which objects could be used to make this

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
