20131006 13:45:25 <Eclesia> opengl question : can we store indexed image on gpu ?
20131006 13:46:32 <sgothel> as texure and use a color lookup shader
20131006 13:47:11 <sgothel> I used that years ago for [x/sdl]MAME
20131006 13:48:18 <Eclesia> so not really an indenpendant texture
20131006 13:48:36 <sgothel> whats that ?
20131006 13:49:03 <Eclesia> I mean a texture which maps colors on it's own
20131006 13:49:14 <Eclesia> like usual rgb texture
20131006 13:49:34 <sgothel> T1[T2[x][y]], w/ T1 == 1D yup
20131006 13:49:48 <Eclesia> ?
20131006 13:50:19 <sgothel> T1 1d-tex color index values, T2 2d tex (indexed image)
20131006 13:51:00 <Eclesia> ha I see, use 2 textures
20131006 13:51:38 <sgothel> use Alpha and RED types (the latter for >= GL3 AFAIK, see FFMEGMedia..Impl)
20131006 13:56:40 <Eclesia> do you have a free(public) blur shader ? XD
20131006 14:00:54 <sgothel> in SDLMAME .. [or look at http://jausoft.com/Files/GLMame/index.html]
20131006 14:01:25 <sgothel> shader-pack includes a few funny mame shader .. multipass blur as well, AFAIK
20131006 14:02:48 <sgothel> http://rbelmont.mameworld.info/?page_id=163 <- should be all visible / avail here, but haven't checked for a while
20131006 14:03:10 <sgothel> AFAIK SDLMAME is now part of MAME
20131006 14:05:14 <Eclesia> nice ... but not free :(
20131006 14:05:18 <Eclesia> Redistributions may not be sold, nor may they be used in a commercial product or activity.
20131006 14:05:53 <sgothel> the shader code is very minimal, as always - just look at it (the math is free) and write it down :)
20131006 14:06:09 <sgothel> my stuff is either BSD'ish or GPLv2 ..
20131006 16:02:40 <Eclesia> hahaha, awesome gif spec
20131006 16:03:08 <Eclesia> just for informations. single image gif are indexed images
20131006 16:03:37 <Eclesia> animated gif are overlapping indexed images != indexed
20131006 17:09:34 <Eclesia> full gif parser. finally :)
