no. > And if not, is it possible (I mean : is it no too huge work) to > update plugins API to work with texture besides pix_block ? hmm, i have thought about that in the past, and i think we should NOT add this capabilities to video/film, BUT... - - i would like to have all (current) plugins (that is: video, film, image and model) to be totally openGL-agnostic. currently all plugins but "model" already adhere to this (apart from using some GL_ constants for colorspaces). "model" does not and this is the reason why model-loading is currently totally broken for the default multi-context builds! - - i *also* think that there is a need to directly input *AND* output textures via plugins. my main motivation for this is actually "syphon"[1] (rather than GPU-based decoding). another motivation is, that in days long gone, [pix_movie] would have optimized paths (at least on OSX), that were faster than the current [pix_film]+[pix_texture] implementation. SO: i think, we need an API for "texin" and "texout" (that's two different plugins!). i guess "video" is a good starting point (without the 'dialog' parts), for both. we have to take care about how to properly support multiple-contexts. (e.g. the texture ID could be different for each window). i'm not entirely sure about the best way to ensure this. internally we could have a texinFILM plugin, that would make all film-plugins available as texture source (just like there is a filmIMAGE plugin, that allows to load images as 1-frame films). [pix_movie] could then be switched to the texin API. and we could have two new objects [tex_input] and [tex_output] as "native" clients of these plugins. fgmadr IOhannes [1] http://syphon.v002.info/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBCAAGBQJUFpzFAAoJELZQGcR/ejb4aisP/iiW9ssrx4eMsB3uNaLrlB7n KGhCK+25sMcnqDDBDbxcMvHoPADvTFEIA7Tta6en9YSpEr7xeaWRedp/2qb0uaYG 05AzWuDoAH4171cF8iwyq8LiiT5/6RjGpvpzhlR7jDYmjgRd7EDz8m6zRUM6u/CO sOpafnvK8EssQkeWO8cMPHXMzwCGdrhMjdoxL953doWgQOeXLDg3UbgYzs0JsRjG ilWrPtRRE05F5rX4/DTmV+ffrL0bVEyaFFeJ5cenDszhN+xY0KhlQeg3RuEVB9tB om7IjngeEKeTRlwHX6GeSaA+H/Mf5pDf14kgfnL49qkgMUDmdRvp/ahFyz/csFPF MERd/QgfwYYvc0J2I7Q5GEPebgPOl4BtyHQreq1y8xMDbGkFs+KqY15jk5Xt4j0N mQNiqr51UtQR5lhPpvjwcPEGADgulcTDH4f1J6o0/00Hz933rpwikxwL1BZH8Scc J4043FEorZvCAkJnBS0RaFBVCeGZsNcKtp1MV8nyBCyKaZrYh7GY7onp5bYOmAgh WEUR3VfY7CjhxLzIHCER7oLYAFc5zPlA5Gfz4IJInZh1MXcJeuWLmjzyr2FvOrOg escx69CTprsB3Qv699KD/73qbMXoyjS3Wh7x22pJxvN0QTwbkgQVvnZNoLDHi9pD eKBfqvlgBCuP4gVTfTeu =QvhL -----END PGP SIGNATURE----- _______________________________________________ GEM-dev mailing list [email protected] http://lists.puredata.info/listinfo/gem-dev
