pf/pdp/3dp in Gem
by Tom Schouten 11 Aug '06

11 Aug '06

hi gemmers, just talking with jamie here in bergen and it's pretty clear to me how to write the bridge between libpdp and Gem. practicly, for me it is the build system. i'd like to add 5 objects. 3 of them are already in the pf/pd bridge. * [gem.get <thing>] : forks off one gemstate object as pdp packet * [gem.set <thing>] : inserts one pdp object in gem state * [pdp <thing>] : generic pdp processors (functional maps) * [3dp <thing] : 3d drawing objects (draw to current gl context) * [pf <script>] : any pf script the last 3 i have C code for and they don't depend on gem, but if pf/pdp/3dp is running inside Gem they need to be included. the first 2 need to be written from scratch as gem objects, possibly just derived from GemBase. i suggest someone helps me with setting this up, by adding templates for the gem.get and gem.set objects in the source tree and add them to the build process. the names are of course open to discussion. anything sane and short. the rest i need is just an init callback. this callback will: * initialize the forth and pdp memory manager * create the pf/pdp/3dp pd objects maybe it is best to keep this optional, since it introduces a library dependency. so, who is motivated to help me out here by adding the templates? i don't have time to learn the build and init process. cheers tom

FYI: rsync mirror

FYI, I just added pd-gem.cvs.sourceforge.net to the automatic nightly rsyncing, so there is a backup of the Gem CVS here now. .hc

Gem for Pd-extended
by hans＠eds.org 27 Jul '06

27 Jul '06

I would like to included Gem in the Pd-extended auto-builds. Anyone up for trying it out? The compile farm is already automatically syncing to the pd-gem CVS every night. Another option is to import a snapshot into the pure-data CVS and build it from there. .hc ------------------------------------------------------------------------ ¡El pueblo unido jamás será vencido!

ortho
by Erich Berger 20 Jul '06

20 Jul '06

hello, i have a question towards ortho: i use the ortho.pd from the gem reference and i change the window dimension to non square (lets say 800 600). without ortho the square looks perfectly square. with ortho the square is distorted in the proportions of the windowsize. why is that so ? merci-best erich --------------------- http://randomseed.org

(if so, you might have to change it in a couple of other files too) if you still get the same errors, then there IS an issue with MMX. you might try to add "-U__MMX__" to the gcc-flags. or add a a "#undef __MMX__" somewhere at the beginning of Base/GemSIMD.h (line 30 seems to be fine) mfg.ads IOhannes

two symbols in constructor?
by james tittle 07 Jul '06

07 Jul '06

hiya, ...I'm trying to add a format and type to the constructor for fbo's, so that we can do something like: [gemframebuffer RGB FLOAT] ...and we'll get an RGB-format, float-type of framebuffer...seems easy enough, but when I try to do: CPPEXTERN_NEW_WITH_TWO_ARG(gemframebuffer, t_symbol *, A_DEFSYMBOL, t_symbol *, A_DEFSYMBOL) gemframebuffer :: gemframebuffer(t_symbol *format, t_symbol *type) ...I all of a sudden get errors saying "A_DEFSYMBOL not a type" and "expected constructor, destructor, or type conversion before 'gemframebuffer'"... what gives? jamie

Smoothing polygon surfaces
by Frank Barknecht 01 Jul '06

01 Jul '06

Hi, I'm playing around a bit with rendering surface equations. I'm using a slightly modified primQuad as in the Gem-examples. Now I'm looking for a way to make these surfaces appear more smoothly, that is, make them look less blocky. Does anyone with more OpenGL-knowledge have an idea, how to do this? (In attached archive, spherical-harm.pd is the main patch.) Ciao -- Frank Barknecht _ ______footils.org_ __goto10.org__
