off to new shores...

hi all. now that the gem-0.90 release is out for some weeks, i think it is time to start some traffic on this list again. (but of course: what to talk about now ? we used to discuss the release for years...) some points: ------- stable: i have branched v0_90 for bug-fixes on the latest stable release -------------------- further development: wini has done some research on opensource-development and has found out that os-dev can be organized effectively in (surprise:) several ways to achieve an optimum development/stability-ratio: (the following is a translation from german and it is already some weeks ago, so i might use the wrong termini) a) pope: one person revises all code and decides which parts of the development should go into the next release b) committee: a small team off people does like the pope. c) branching: each new feature is branched off the main CVS-trunk. as soon as it has become stable the branch is merged with the main trunk. i don't think that a) would be a very good idea (as it has proven to lead to major quarrels and misunderstanding) as for b) it seems like a bit of an overhead, as the core-development team is so small, that all of us would be in the committee. so i favour c) (with some b)): each development should be forked into a separate branch in the CVS; the core-developpers of this branch work on the code until they consider it stable and then make a call for testing via the list. after it has proven to run stable on all platforms this tree is merged back in. i would suggest that the releasing should be done on each merge of a development-branch to the main-trunk that adds new functionality. (this can be discussed; it is just fundamentally different from the last release) the main-trunk can be used for bug-fixing... ------------- new features: i'm looking forward to vertex-manipulation, pixel-shaders, multiple gemwins, MMX/SSE2, new pixel-effects, pixel-analysis and tons of other things. cheers, comments ? and happy coding mfg.as.dr IOhannes

(this would especially be useful, as i have noticed major problems with libquicktime: a) arbitrarily freezes on 2.6-systems; b) wrong build-configuration does not detect the plugin-path) mfg.a.sdr IOhannes > know.

Hi!, this its RBF-soft Would be posible to do some code to be able to manage avi-file instead of videostreaming with the pd-gem object pix_video_DS Â¿?. If this will be posible any new codec will be played by video object. I say that because any of the recent release of Gem in WXP can do video in any codec. Also the new features of qt are not working. Of course thanks for the big work in the debelopment of pd-gem. See u later, rodri_DJ & ivan_VJ RBF-soft.

Re: [PD] Bug with [pix_film] on os X
by chris clepper 10 Jul '04

10 Jul '04

This is a bug with Nvidia's drivers which do not handle YUV textures properly. You can sned pix_film a 'colorspace rgb' message, but this will drastically reduce performance. If you want to get an ATI card like an 8500 or better, then that will solve the problem quite well. You can also go back to a version of OSX before 10.2.6 and that might work, but it's been quite some time since I've tried that. Also, I think you are mistaken about pix_movie not doing this - it's the exact same code as pix_film + pix_texture just wrapped in a single object. Maybe the default is set to RGB colorspace - I don't recall off hand. This is also the first I've heard of starting and stopping rendering 'fixing' the problem. This issue has been confirmed by many other developers including the VLC people, and an official bug is on file with Apple (Nividia have no real OSX developer support at all). cgc Quoting Etienne Desautels <titi(a)sat.qc.ca>: > Hi, > > I'm actually developing some patches on PD 0.37 with Gem 0.9 on os X, > but I find a bug with the [pix_film] object.

open GL transformation matrix question
by cyrille henry 02 Jul '04

02 Jul '04

hello, I've got a question regarding translormation matrix with gem. I'm using some combination of translate/rotate/translate etc to draw some shape. At the end of this shape, I want to draw a cube by exemple. the problem is that I want to draw the cube to a defined orientation. Ss The cube position if defined with lot's of diferent translate/rotate, I'm not able to know it's curent orientation. I don't "know" it's position too. so, is it possible to imagine an object that could output the curent transformation matrix into the pd patch? if it's not possible, does anyone know how could I solve my problem. thanks Cyrille

branch: SIMD
by zmoelnig＠iem.at 01 Jul '04

01 Jul '04

i have done another branch (since it is so funny): SIMD; as the name says, it is for getting MMX/SSE2 (and Altivec, if there is something left to do) to work. btw: are there any include-files you need for AltiVec with gcc ? i haven't found anything in the sources, but MMX/SSE2 need files for intrinsics (icc, gcc and vc6), so i was wondering... mfg.a.dr IOhannes
